Hi Pierre,
okay, I looked at FindSDL.cmake more carefully. First I think you should
make sure that SDL is actually found. You should have something like
this in you cmakeLists.txt:
find_package(SDL)
if( NOT SDL_FOUND )
message( "Warning: SDL not found" )
endif( NOT SDL_FOUND )
or since you need it anyway for your package:
find_package(SDL REQUIRED)
than cmake stops if SDL isn't found (actually not, since FindSDL.cmake
misses this feature :).
Anyway, from what I see, you set the path SDLMAIN_LIBRARY, but libsdl.a
is not found, since you don't tell it where to find it. it is much
better to use environment variables here, e.g.
set CMAKE_LIBRARY_PATH=c:\sdl\lib
set CMAKE_INCLUDE_PATH=c:\sdl\include
cmake ..
or for msys
export CMAKE_LIBRARY_PATH=pathtosdl/lib
export CMAKE_INCLUDE_PATH=pathtosdl/include
cmake ..
Than if cmake looks for includes (any kind) it also searches in
CMAKE_INCLUDE_PATH and if it looks for libraries (any kind) it searches
in also CMAKE_LIBRARY_PATH. FindSDL.cmake should than find automatically
the sdl headers and the libraries, I assume they are in the same
directory. If not you could set it like that:
export CMAKE_LIBRARY_PATH=pathtosdl/lib/main:pathtosdl/lib/image
But still you need to change BOTH (!) "IF(MINGW)" clauses to "IF(MINGW
AND MSYS)" if you want to use msys.
HTH,

- launched CMake,

SDLIMAGE_INCLUDE_DIR, SDLIMAGE_LIBRARY, SDL_INCLUDE_DIR, SDLMAIN_LIBRARY).
- generated the makefiles.
- click on start menu, and click on the launcher.
- launched "cmd" (I suppose that this is what you called Windows CLI)
- went to the directory
- launched "mingw32-make.exe"
And the error is the same as before. The "build.make" is the same as
before (I copied the linking part at the end of this mail).
Any idea?
I would like to check the value of the variables in the FindSDL.cmake
(like "MINGW"...) when I try to compile
my program. Is this possible?
Can the problem be relevant to the fact that I am using the MINGW
version coming with Qt ?
Another solution would be to
change the lines above to
IF(MINGW AND MSYS)
SET(MINGW32_LIBRARY mingw32 CACHE STRING "mwindows for MinGW")
ENDIF(MINGW AND MSYS)
and similar code in FindSDL.cmake. This should work than.
Currently, I suppose that the first issue is not related to that, as
even with
MINGW it does not work...
Any idea?
