|

Everyone is permitted to copy and distribute verbatim copies
|

of this license document, but changing it is not allowed.
|
||||
All rights reserved.
|
||||
|
||||
Preamble
|
||||
Redistribution and use in source and binary forms, with or without modification, are
|
||||
permitted provided that the following conditions are met:
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Lesser General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
1. Redistributions of source code must retain the above copyright notice, this list of
|
||||
conditions and the following disclaimer.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
2. Redistributions in binary form must reproduce the above copyright notice, this list of
|
||||
conditions and the following disclaimer in the documentation and/or other materials
|
||||
provided with the distribution.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
3. Neither the name of the copyright holder nor the names of its contributors may be used
|
||||
to endorse or promote products derived from this software without specific prior written
|
||||
permission.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.

|
||||
|
||||
You should have received a copy of the GNU General Public License along
|
||||
with this program; if not, write to the Free Software Foundation, Inc.,
|
||||

|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||

|
||||
This is free software, and you are welcome to redistribute it
|

under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||

This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Lesser General
|
||||
Public License instead of this License.

i2pd
|
||||
====
|
||||
|
||||
I2P router written in C++
|
||||
[Русская версия](https://github.com/PurpleI2P/i2pd_docs_ru/blob/master/README.md)
|
||||
|
||||
Requirements for Linux/FreeBSD/OSX
|
||||
----------------------------------
|
||||
i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.
|
||||
|
||||
GCC 4.6 or newer, Boost 1.46 or newer, crypto++. Clang can be used instead of
|
||||
GCC.
|
||||
I2P (Invisible Internet Protocol) is a universal anonymous network layer.
|
||||
All communications over I2P are anonymous and end-to-end encrypted, participants
|
||||
don't reveal their real IP addresses.
|
||||
|
||||
Requirements for Windows
|
||||
------------------------
|
||||
I2P client is a software used for building and using anonymous I2P
|
||||
networks. Such networks are commonly used for anonymous peer-to-peer
|
||||
applications (filesharing, cryptocurrencies) and anonymous client-server
|
||||
applications (websites, instant messengers, chat-servers).
|
||||
|
||||
VS2013 (known to work with 12.0.21005.1 or newer), Boost 1.46 or newer,
|
||||
crypto++ 5.62. See Win32/README-Build.txt for instructions on how to build i2pd
|
||||
and its dependencies.
|
||||
I2P allows people from all around the world to communicate and share information
|
||||
without restrictions.

-------
|
||||
|
||||
First, build it.
|
||||
|
||||
* $ cd i2pd
|
||||
* $ make
|
||||
|
||||
Next, find out your public ip. (find it for example at http://www.whatismyip.com/)
|
||||
|
||||
Then, run it with:
|
||||
|
||||
$ ./i2p --host=YOUR_PUBLIC_IP
|
||||
|
||||
The client should now reseed by itself.
|
||||
|
||||
To visit an I2P page, you need to find the b32 address of your destination.
|
||||
After that, go to the webconsole and add it behind the url. (Remove http:// from the address)
|
||||
|
||||
This should resulting in for example:
|
||||
http://localhost:7070/4oes3rlgrpbkmzv4lqcfili23h3cvpwslqcfjlk6vvguxyggspwa.b32.i2p
|
||||
|
||||
|
||||
Cmdline options
|
||||
---------------
|
||||
|
||||
* --host= - The external IP
|
||||
* --port= - The port to listen on
|
||||
* --httpport= - The http port to listen on
|
||||
* --log= - Enable or disable logging to file. 1 for yes, 0 for no.
|
||||
* --daemon= - Enable or disable daemon mode. 1 for yes, 0 for no.
|
||||
* --service= - 1 if uses system folders (/var/run/i2pd.pid, /var/log/i2pd.log, /var/lib/i2pd).
|
||||
* --unreachable= - 1 if router is declared as unreachable and works through introducers.
|
||||
* --v6= - 1 if supports communication through ipv6, off by default
|
||||
* --httpproxyport= - The port to listen on (HTTP Proxy)
|
||||
* --socksproxyport= - The port to listen on (SOCKS Proxy)
|
||||
* --ircport= - The local port of IRC tunnel to listen on. 6668 by default
|
||||
* --ircdest= - I2P destination address of IRC server. For example irc.postman.i2p
|
||||
* --irckeys= - optional keys file for local destination
|
||||
* --eepkeys= - File name containing destination keys, for example privKeys.dat.
|
||||
The file will be created if it does not already exist (issue #110).
|
||||
* --eephost= - Address incoming trafic forward to. 127.0.0.1 by default
|
||||
* --eepport= - Port incoming trafic forward to. 80 by default
|
||||
* --samport= - Port of SAM bridge. Usually 7656. SAM is off if not specified
|
||||

|
||||
* --conf= - Config file (default: ~/.i2pd/i2p.conf or /var/lib/i2pd/i2p.conf)
|
||||
This parameter will be silently ignored if the specified config file does not exist.
|
||||
Options specified on the command line take precedence over those in the config file.
|
||||
|
||||
Config file
|
||||
-----------
|
||||
|
||||
INI-like, syntax is the following : <key> = <value>.
|
||||
All command-line parameters are allowed as keys, for example:
|
||||
|
||||
log = 1
|
||||
v6 = 0
|
||||

|
||||
=========================
|
||||
|
||||
Requirements for building:
|
||||
|
||||
* Visual Studio 2013 (tested with VS2013 Update 1, Update 3, and Update 4 RC)
|
||||
* Boost (tested with 1.56 and 1.57)
|
||||
* Crypto++ (tested with 5.6.2)
|
||||
|
||||
|
||||

|
||||
|
||||
cd C:\path\to\boost\sources
|
||||
bootstrap
|
||||
b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\Win32 install --with-filesystem --with-program_options --with-regex --with-date_time

Building Boost (64-bit)
|
||||
-----------------------
|
||||
|
||||
Open a Visual Studio x64 command prompt and run the following:
|
||||
|
||||
cd C:\path\to\boost\sources
|
||||
bootstrap
|
||||
b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\x64 architecture=x86 address-model=64 install --with-filesystem --with-program_options --with-regex --with-date_time
|
||||
|
||||
After Boost is compiled, set the environment variable `BOOST` to the directory
|
||||
Boost was installed to. If you followed the instructions outlined here, you
|
||||
should set it to `C:\Boost`. Additionally, set the BOOSTVER variable to the
|
||||
version of Boost that you're using, but instead of a '.' use a '_'. For
|
||||
example, I have `BOOSTVER` set to `1_57`.
|
||||
|
||||
Building Crypto++
|
||||
-----------------
|
||||
|
||||
* Open the crypttest Solution in VS2013
|
||||
* Visual Studio will ask to update the Solution/Project. Allow it.
|
||||
* Build the `cryptopp` project, both the Debug and Release targets and for both
|
||||
Win32 and x64.
|
||||
* Create a folder called `cryptopp` in the crypto++ source directory, then copy
|
||||
the header files to this new directory.
|
||||
* Set the `CRYPTOPP` environment variable pointing to the Crypto++ source directory.
|
||||
|
||||
|
||||
Building i2pd
|
||||
-------------
|
||||
|
||||
## Prep work ##
|
||||
|
||||
I strongly advise setting up your own `INCLUDES` and `LIBS` instead of relying
|
||||
on the settings in the i2pd project file. By using your own settings, if the
|
||||
i2pd devs change the paths in the project file, your builds will still work.
|
||||
|
||||
To do this, create or edit the file
|
||||
`%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user`.
|
||||
|
||||
For comparison, my file is reproduced below:
|
||||
|
||||
<?xml version="1.0" encoding="utf-8"?>
|
||||
<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
|
||||
<ImportGroup Label="PropertySheets">
|
||||
</ImportGroup>
|
||||
<PropertyGroup Label="UserMacros" />
|
||||
<PropertyGroup>
|
||||
<LibraryPath>$(CRYPTOPP)\$(Platform)\Output\$(Configuration);$(BOOST)\lib\$(Platform);$(LibraryPath)</LibraryPath>
|
||||
<IncludePath>$(CRYPTOPP);$(BOOST)\include\boost-$(BOOSTVER);$(IncludePath)</IncludePath>
|
||||
</PropertyGroup>
|
||||
<ItemDefinitionGroup />
|
||||
<ItemGroup />
|
||||
</Project>
|
||||
|
||||
|
||||
If you want to build x64 binaries as well, you'll want to edit or create the
|
||||
file `%localappdata%\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user`. If you
|
||||
followed the steps outlined earlier you can copy (or link) the win32 file to
|
||||
the x64 one.
|
||||
|
||||
## Anti-Climatic End ##
|
||||
|
||||
After following the above instructions, you'll be able to build Debug Win32,
|
||||
Debug x64, Release Win32, and Release x64 i2pd binaries.
