Building on Linux

# or your OS or distro's package manager
$ sudo apt install build-essential libtool autoconf cmake git
$ git clone --recursive https://github.com/loki-project/lokinet-builder
$ cd lokinet-builder
$ make 

Building on Windows (mingw-w64 native, or wow64/linux/unix cross-compiler)

#i686 or x86_64
#if cross-compiling from anywhere other than wow64, export CC and CXX to
#$ARCH-w64-mingw32-g[cc++] respectively
$ pacman -Sy base-devel mingw-w64-$ARCH-toolchain git libtool autoconf cmake
$ git clone --recursive https://github.com/loki-project/lokinet-builder
$ cd lokinet-builder
$ make ensure sodium
$ cd build
$ cmake ../deps/llarp -DSODIUM_LIBRARIES=./prefix/lib/libsodium.a -DSODIUM_INCLUDE_DIR=./prefix/include -G "Unix Makefiles" -DHAVE_CXX17_FILESYSTEM=ON
$ make
$ cp llarpd ../lokinet.exe

Building on Windows using Microsoft C/C++ (Visual Studio 2017)

  • clone https://github.com/loki-project/lokinet-builder from git-bash or whatever git browser you use
  • open %CLONE_PATH%/lokinet-builder/deps/sodium/builds/msvc/vs2017/libsodium.sln and build one of the targets
  • create a build folder in %CLONE_PATH%/lokinet-builder
  • run cmake-gui from %CLONE_PATH%/lokinet-builder/deps/llarp as the source directory
    • define SODIUM_LIB to %CLONE_PATH%/lokinet-builder/deps/sodium/bin/win32/%CONFIG%/%TOOLSET%/%TARGET%/libsodium.lib
    • define SODIUM_INCLUDE_DIR to %CLONE_PATH%/lokinet-builder/deps/sodium/src/libsodium/include
    • define HAVE_CXX17_FILESYSTEM to TRUE
    • select Visual Studio 2017 15 %ARCH% as the generator
    • enter a custom toolset if desired (usually v141_xp)
  • generate the developer studio project files and open in the IDE
  • select a configuration
  • press F7 to build everything

Running

$ ./lokinet

or press Debug/Local Windows Debugger in the visual studio standard toolbar

Development

Please note development builds are likely to be unstable.

Build requirements:
  • CMake
  • ninja (for unit testing with Google Tests)
  • libsodium >= 1.0.14 (included here)
  • c++ 11 capable C++ compiler
  • if you have C++17 <filesystem> or <experimental/filesystem> declared and defined in your platform's C++ toolchain, re-run CMake (in lokinet-builder/build) with -DHAVE_CXX17_FILESYSTEM=ON.
  • since each platform seems to have its own idea of where std::[experimental::]filesystem is defined, you will need to manually specify its library in LDFLAGS or CMAKE_x_LINKER_FLAGS as well.
Windows:
  • Mingw-w64 is recommended for 32 or 64-bit builds.
  • It is possible to compile with Microsoft C++ (v19 or later from VS2015+).
  • cpp17::filesystem in vendor/cppbackport-master is not available for Windows.

Boxed warning

Inbound sessions are unsupported on Windows Server systems.

Ignore this warning at your own peril.

Building a debug build:
