CrossCompilation Windows sous Linux

[wamilou]

Bonjour à tous,

J'ai tenté de compiler sfml pour Windows à partir d'une machine Linux ( automatisation grâce à Jenkins ). Je suis arrivé à résoudre 2-3 problèmes mais là je bloque.

En fait, je ne comprends pas pourquoi cmake tente de trouver X11 pour compiler pour Windows ...

Script shell pour compiler :

cmake -G "Unix Makefiles" -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_C_COMPILER=i586-mingw32msvc-gcc -DCMAKE_CXX_COMPILER=i586-mingw32msvc-g++ -DCMAKE_RC_COMPILER=i586-mingw32msvc-windres -DOPENAL_LIBRARY=libopenal32.a ..
make

Et voici la sortie de la console :

cmake -G Unix Makefiles -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_C_COMPILER=i586-mingw32msvc-gcc -DCMAKE_CXX_COMPILER=i586-mingw32msvc-g++ -DCMAKE_RC_COMPILER=i586-mingw32msvc-windres -DOPENAL_LIBRARY=libopenal32.a ..

Si quelqu'un aurait une idée pour fixer ce problème, je prends !
Merci d'avance pour les futures réponses à mon problème.

Bon, je vais remonter mon vieux sujet mais je suis arrivé à résoudre les problèmes durant la configuration cmake.

Maintenant c'est lors de la compilation que le compilateur ne trouve pas GL/glew.h

Voici ce que j'ai tapé pour cmake

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/etc/toolchains/windows.cmake -DGLEW_LIBRARY=./extlibs/libs-mingw/x86/lib/libglew.a -DGLEW_INCLUDE_PATH=./extlibs/headers -DJPEG_LIBRARY=./extlibs/libs-mingw/x86/libjpeg.a -DJPEG_INCLUDE_DIR=./extlibs/headers/jpeg -DOPENAL_LIBRARY=./extlibs/libs-mingw/x86/libopenal32.a -DOPENAL_INCLUDE_DIR=./extlibs/headers/AL -DFREETYPE_LIBRARY=./extlibs/libs-mingw/x86/libfreetype.a -DFREETYPE_INCLUDE_DIRS=./extlibs/headers/libfreetype/windows -DSNDFILE_LIBRARY=./extlibs/libs-mingw/x86/libsndfile.a -DSNDFILE_INCLUDE_DIR=./extlibs/headers/libsndfile/windows

Et voici mon fichier qui défini la toolchain de Windows sous linux

# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)

# which compilers to use for C and C++
SET(CMAKE_C_COMPILER i586-mingw32msvc-gcc)
SET(CMAKE_CXX_COMPILER i586-mingw32msvc-g++)
SET(CMAKE_RC_COMPILER i586-mingw32msvc-windres)

# here is the target environment located
SET(CMAKE_FIND_ROOT_PATH /usr/i586-mingw32msvc)

# adjust the default behaviour of the FIND_XXX() commands:
# search headers and libraries in the target environment, search
# programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Si quelqu'un a une idée pourquoi le compilateur ne trouve pas GL/glew.h, alors que j'ai bien défini lors de la configuration où se situer les librairies Windows.
