# Building thrift on Windows (MinGW64/MSYS2)

Thrift uses cmake to make it easier to build the project on multiple platforms, however to build a fully functional and production ready thrift on Windows requires a number of third party libraries to be obtained.  Once third party libraries are ready, the right combination of options must be passed to cmake in order to generate the correct environment.

> Note: libevent and libevent-devel do not work with this toolchain as they do not properly detect mingw64 and expect some headers to exist that do not, so the non-blocking server is not currently built into this solution.

## MSYS2

Download and fully upgrade msys2 following the instructions at:

    https://msys2.github.io/

Install the necessary toolchain items for C++:

    $ pacman --needed -S bison flex make mingw-w64-x86_64-openssl \
                mingw-w64-x86_64-boost mingw-w64-x86_64-cmake \
                mingw-w64-x86_64-toolchain mingw-w64-x86_64-zlib

Update your msys2 bash path to include /mingw64/bin by adding a line to your ~/.bash_profiles using this command:

    echo "export PATH=/mingw64/bin:\$PATH" >> ~/.bash_profile

After that, close your shell and open a new one.

Use cmake to create a MinGW makefile, out of tree (assumes you are in the top level of the thrift source tree):

    mkdir ../thrift-build
    cd ../thrift-build
    cmake -G"MinGW Makefiles" -DCMAKE_MAKE_PROGRAM=/mingw64/bin/mingw32-make \
       -DCMAKE_C_COMPILER=x86_64-w64-mingw32-gcc.exe \
       -DCMAKE_CXX_COMPILER=x86_64-w64-mingw32-g++.exe \
       -DWITH_BOOSTTHREADS=ON -DWITH_LIBEVENT=OFF \
       -DWITH_SHARED_LIB=OFF -DWITH_STATIC_LIB=ON \
       -DWITH_JAVA=OFF -DWITH_PYTHON=OFF -DWITH_PERL=OFF \
       ../thrift

Build thrift (inside thrift-build):

    cmake --build .

Run the tests (inside thrift-build):

    ctest

> If you run into issues, check Apache Jira THRIFT-4046 for patches relating to MinGW64/MSYS2 builds.

## Tested With

msys2 64-bit 2016-10-26 distribution

# Apache Thrift - CMake build

## Goal
Extend Apache Thrift's *make cross* approach to the build system.

Due to growing the field of operating system support, a proper executable
and library detection mechanism running on as much platforms as possible
becomes required. The other aspect to simplify the release process and
package generation process.

As nice side benefit of CMake is the generation of development environment
specific soultion files. => No solution files within source tree.


## Usage
just do this:

    mkdir cmake-build && cd cmake-build
    cmake ..

if you use a specific toolchain pass it to cmake, the same for options:

    cmake -DCMAKE_TOOLCHAIN_FILE=../build/cmake/mingw32-toolchain.cmake ..
    cmake -DCMAKE_C_COMPILER=clang-3.5 -DCMAKE_CXX_COMPILER=clang++-3.5 ..
    cmake -DTHRIFT_COMPILER_HS=OFF ..
    cmake -DWITH_ZLIB=ON ..

or on Windows

    cmake -G "Visual Studio 12 2013 Win64" \
    -DBOOST_ROOT=C:/3rdparty/boost_1_58_0 \
    -DZLIB_ROOT=C:/3rdparty/zlib128-dll \
    -DWITH_SHARED_LIB=off -DWITH_BOOSTTHREADS=ON ..

and open the development environment you like with the solution or do this:

    make
    make check
    make cross
    make dist

to generate an installer and distribution package do this:

    cpack

* git hash or tag based versioning depending on source state
* build tutorial
* build test
* with/without language lib/<lang>/
* enable/disable
* make cross
* make dist (create an alias to make package_source)
* make doc
* cpack (C++ and make dist only ?)
  * thrift-compiler

  * tutorial
  * test
* merge into /README.md
