This documentation aims at guiding the developer with cross-compilation for the Windows target using MinGW-w64 project. This is the method used to ship the windows binaries that include Python bindings.
The cross-compilation is straightforward thanks to the provided precompiled MinGW toolchain and libraries:
Install Wine, NSIS:
aptitude install wine nsis
Fetch the last openturns-developers-windeps-x.y.tgz archive and unzip it:
cd openturns-src/distro/windows wget http://downloads.sourceforge.net/openturns/openturns/openturns-1.8/dev/openturns-developers-windeps-1.8.tar.gz tar xzf openturns-developers-windeps-1.8.tar.gz
make make ARCH=x86_64 # (for a 64 bits target) make PYBASEVER=3.5 # (for Python 3.5)
If you are lucky, it should produce an installer named openturns-x.y-pyu.v-arch.exe
A successful build of the library according to the previous step is required to compile a module from its sources:
cd module-src/distro/windows make OT_PREFIX=$PWD/../../../openturns-src/build-i686-w64-mingw32/install
The same Makefile variables can be set (the same way the library was built) to control the build parameters. If the build is successful an executable installer is created.
