Сборка на Windows ================= There are two approaches available to build i2pd on Windows. The best one depends on your needs and personal preferences. One is to use msys2 and [unix alike infrastructure](build_notes_unix.md). Another one is to use Visual Studio. While there might be no difference for end users of i2pd daemon, developers, however, shall be wary of differences in C++ name mangling between the two compilers when making a choice to be able to link their software against libi2pd. If you are a stranger to C++ with no development tools installed on your system and your only goal is to have i2pd up and running from the most recent source, consider using msys2. Although it relies on command line operations, it should be straight forward. In this guide, we will use CMake for both approaches and we will assume that you typically have your projects in C:\dev\ as your development location for the sake of convenience. Adjust paths accordingly if it is not the case. Note that msys uses unix-alike paths like /c/dev/ for C:\dev\. msys2 ----- ### x86 (32-bit architecture) Get install file msys2-i686-*.exe from https://msys2.github.io. open MSYS2 Shell (from Start menu). Install all prerequisites and download i2pd source: ```bash pacman -S mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-gcc git make mkdir -p /c/dev/i2pd cd /c/dev/i2pd git clone https://github.com/PurpleI2P/i2pd.git cd i2pd export PATH=/mingw32/bin:/usr/bin # we need compiler on PATH which is usually heavily cluttered on Windows make ``` ### x64 (64-bit architecture) Get install file msys2-x86_64-*.exe from https://msys2.github.io. open MSYS2 Shell (from Start menu). Install all prerequisites and download i2pd source: ```bash pacman -S mingw-w64-x86_64-boost mingw-w64-x86_64-openssl mingw-w64-x86_64-gcc git make mkdir -p /c/dev/i2pd cd /c/dev/i2pd git clone https://github.com/PurpleI2P/i2pd.git cd i2pd export PATH=/mingw64/bin:/usr/bin # we need compiler on PATH which is usually heavily cluttered on Windows make ``` ### Caveats It is important to restrict PATH as described above. If you have Strawberry Perl and/or Mercurial installed, it will pick up gcc & openssl from the wrong places. If you do use precompiled headers to speed up compilation (recommended), things can go wrong if compiler options have changed for whatever reason. Just delete `stdafx.h.gch` found in your build folder, note the file extension. If you are an Arch Linux user, refrain from updating system with `pacman -Syu`. Always update runtime separately as described on the home page, otherwise you might end up with DLLs incompatibility problems. ### AES-NI If your processor has [AES instruction set](https://en.wikipedia.org/wiki/AES_instruction_set), you use `make USE_AESNI=1`. No check is done however, it will compile, but it might crash with `Illegal instruction` if not supported. You should be able to run ./i2pd . If you need to start from the new shell, consider starting *MinGW-w64 Win32 Shell* instead of *MSYS2 Shell* as it adds`/minw32/bin` to the PATH. ### UPnP You can install it through the MSYS2 and build with USE_UPNP key. ```bash pacman -S mingw-w64-i686-miniupnpc make USE_UPNP=yes ``` or ```bash pacman -S mingw-w64-x86_64-miniupnpc make USE_UPNP=yes ``` Using Visual Studio ------------------- Requirements for building: * [CMake](https://cmake.org/) (tested with 3.1.3) * [Visual Studio Community Edition](https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx) (tested with VS2013 Update 4) * [Boost](http://www.boost.org/) (tested with 1.59) * Optionally [MiniUPnP](http://miniupnp.free.fr) (tested with 1.9), we need only few client headers * OpenSSL (tested with 1.0.1p and 1.0.2e), if building from sources (recommended), you'll need as well * [Netwide assembler](http://www.nasm.us/) * Strawberry Perl or ActiveState Perl, do NOT try msys2 perl, it won't work ### Building Boost Open a Command Prompt (there is no need to start Visual Studio command prompt to build Boost) and run the following: cd C:\dev\boost bootstrap b2 toolset=msvc-12.0 --build-type=complete --with-filesystem --with-program_options --with-date_time If you are on 64-bit Windows and you want to build 64-bit version as well b2 toolset=msvc-12.0 --build-type=complete --stagedir=stage64 address-model=64 --with-filesystem --with-program_options --with-date_time After Boost is compiled, set the environment variable `BOOST_ROOT` to the directory Boost was unpacked to, e.g., C:\dev\boost. If you are planning on building only particular variant, e.g. Debug only and static linking, and/or you are out of space/time, you might consider `--build-type=minimal`. Take a look at [appveyor.yml](../appveyor.yml) for details on how test builds are done. ### Building OpenSSL Download OpenSSL, e.g. with git git clone https://github.com/openssl/openssl.git cd openssl git checkout OpenSSL_1_0_1p Now open Visual Studio command prompt and change directory to that with OpenSSL set "PATH=%PATH%;C:\Program Files (x86)\nasm" perl Configure VC-WIN32 --prefix=c:\OpenSSL-Win32 ms\do_nasm nmake -f ms\ntdll.mak nmake -f ms\ntdll.mak install You should have it installed into C:\OpenSSL-Win32 by now. Note that you might consider providing `-DOPENSSL_ROOT_DIR` to CMake and/or create a symlink (with mklink /J) to C:\OpenSSL if you plan on maintaining multiple versions, e.g. 64 bit and/or static/shared. Consult `C:\Program Files (x86)\CMake\share\cmake-3.3\Modules\FindOpenSSL.cmake` for details. ### Get miniupnpc If you are behind a UPnP enabled router and don't feel like manually configuring port forwarding, you should consider using [MiniUPnP](http://miniupnp.free.fr) client. I2pd can be built capable of using miniupnpc shared library (DLL) to open up necessary port. You'd want to have include headers around to build i2pd with support for this. Unpack client source code in a sibling folder, e.g. C:\dev\miniupnpc . You may want to remove version number from folder name included in downloaded archive. ### Creating Visual Studio project Start CMake GUI, navigate to i2pd directory, choose building directory, e.g. ./out, and configure options. Alternatively, if you feel adventurous, try that from the command line ``` cd mkdir out cd out cmake ..\build -G "Visual Studio 12 2013" -DWITH_UPNP=ON -DWITH_PCH=ON -DCMAKE_INSTALL_PREFIX:PATH=C:\dev\Debug_Win32_stage ``` WITH_UPNP will stay off, if necessary files are not found. ### Building i2pd You can open generated solution/project with Visual Studio and build from there, alternatively you can use `cmake --build . --config Release --target install` or [MSBuild tool](https://msdn.microsoft.com/en-us/library/dd293626.aspx) `msbuild i2pd.sln /p:Configuration=Release`.
