Cross-Compile STK on Linux with MinGW | Issue

[PT400C]

Hello,

when trying to compile STK with MinGW on Debian9 for Windows-64, I encounter lots of errors within the Irrlicht lib.

Example 1:

{l Code}: {l Select All Code}

lib/irrlicht/CMakeFiles/stkirrlicht.dir/build.make:138: recipe for target 'lib/irrlicht/CMakeFiles/stkirrlicht.dir/source/Irrlicht/CBoneSceneNode.cpp.obj' failed
make[2]: *** [lib/irrlicht/CMakeFiles/stkirrlicht.dir/source/Irrlicht/CBoneSceneNode.cpp.obj] Error 1

   swprintf(buf, 32, L"%p", Value);


Example 2:

{l Code}: {l Select All Code}

lib/irrlicht/CMakeFiles/stkirrlicht.dir/build.make:113: recipe for target 'lib/irrlicht/CMakeFiles/stkirrlicht.dir/source/Irrlicht/CBillboardSceneNode.cpp.obj' failed

   snprintf(tmpbuf, 255, "%0.6f", number);


Any idea what could be wrong with these parts of irrlicht? And what did I do wrong?

Thanks in advance

We do not officially support cross-compiling so I'm afraid you're going off the beaten path here and we won't be able to provide much help, unfortunatley

Assuming that you have g++-mingw-w64 and gcc-mingw-w64 installed, and you have "dependencies" directory (the same as for normal mingw compilation on windows) you can just use:

{l Code}: {l Select All Code}

cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-mingw-64bit.cmake
make


I was doing it multiple times on ubuntu and I think that it should work on debian in the same way. I can check on debian buster later.

The only thing is that on some mingw versions 32bit complation fails when building angelscript, so maybe better use 64bit version.

I just checked and 64-bit compilation works without issues on debian buster using mingw from repositories.

For 32-bit compilation it still needs this patch:
