The great thing is that cross compiling was very simple with to setup with CMake in my case, I didn't require a "special" CMakeLists.txt.
All I do is create a file e.g. "setmingw" with: export CC=i586-mingw32msvc-gcc export CXX=i586-mingw32msvc-g++ export LD=i586-mingw32msvc-ld export AR=i586-mingw32msvc-ar export AS=i586-mingw32msvc-as export NM=i586-mingw32msvc-nm export STRIP=i586-mingw32msvc-strip export RANLIB=i586-mingw32msvc-ranlib export DLLTOOL=i586-mingw32msvc-dlltool export OBJDUMP=i586-mingw32msvc-objdump export RESCOMP=i586-mingw32msvc-windres export CFLAGS= then a % source setmingw % cmake % make Unfortunately the command SET_TARGET_PROPERTIES( ...) doesn't solve the library problem, linking against the library will result in "cannot find -lexample.dll" (here the dll suffix is to much) The thing that works is renaming the libraries e.g. libexample.so to example.dll I wasn't aware that CMake does not support cross-compiling. Apart from linking against the library with the correct prefix/suffix it works in my case. Also I didn't know the option CROSS_MINGW32, however it setting the option doesn't solve the problem.

I am really interested in getting sample CMakeLists.txt since I just wanted to do what you've done, i.e. cross-compiling for win32 under linux. You should know that CMake does not currently support cross-compiling. See http://www.cmake.org/pipermail/cmake/2006-September/010959.html or http://www.cmake.org/pipermail/cmake/2006-September/010946.html For your "problem" I think you may try this in your project CMakeLists.txt IF (UNIX) IF (CROSS_MINGW32) SET(MY_TARGETLIB_PREFIX "") SET(MY_TARGETLIB_SUFFIX ".dll") ELSE (CROSS_MINGW32) SET(MY_TARGETLIB_PREFIX "lib") SET(MY_TARGETLIB_SUFFIX ".so") ENDIF (CROSS_MINGW32) ENDIF (UNIX) I assume OPTION(CROSS_MINGW32 "Cross compile Win32 using mingw32" OFF) was set ON for mingw32 cross compiling and OFF for Linux "native" compiling. Then use your MY_TARGETLIB_xxx in all other places: SET_TARGET_PROPERTIES(ex1 PROPERTIES PREFIX $(MY_TARGETLIB_PREFIX) SUFFIX $(MY_TARGETLIB_SUFFIX) ) 2006/11/16, Peter Visser <[EMAIL PROTECTED]>: > Hi, > > I have a working build under win32 with MSYS/MINGW, now I would like to > cross-compile code for win32 with mingw from linux with by using the same > CMakelists.txt files.
