[CMake] Impossible to link SDLmain and LibXml2
Hi, I have a problem with cmake not to compile but to link my .exe. I use SDL, OpenGL, FMOD, LibXml2 and a personal library. But when I try to compile my program LibXml2 and SDLmain are not include into the command line to link my .exe. Enclosed my CMakeList.txt and CMakeCache.txt and here the line for the linker into build.make: Output/shootspace.exe: C:/MinGW/lib/libSDL.dll.a Output/shootspace.exe: C:/MinGW/lib/libfmodex.a Output/shootspace.exe: CMakeFiles/shootspace.dir/build.make Output/shootspace.exe: CMakeFiles/shootspace.dir/objects1.rsp @$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --red --bold Linking CXX executable Output/shootspace.exe /c/Program Files (x86)/CMake 2.8/bin/cmake.exe -E remove -f CMakeFiles/shootspace.dir/objects.a /C/MinGW/bin/ar.exe cr CMakeFiles/shootspace.dir/objects.a @CMakeFiles/shootspace.dir/objects1.rsp /C/MinGW/bin/g++.exe -Wl,--whole-archive CMakeFiles/shootspace.dir/objects.a -Wl,--no-whole-archive -o Output/shootspace.exe -Wl,--out-implib,Output/libshootspace.dll.a -Wl,--major-image-version,0,--minor-image-version,0 -Lsource/lib/gtl/lib/mingw -lmingw32 /C/MinGW/lib/libSDL.dll.a -lpthread -lglu32 -lopengl32 /C/MinGW/lib/libfmodex.a -lgtl -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 As you can see, LibXml2 library and SDLmain library are found in CMakeCache.txt but not include in build.make because lxml2 and lSDLmain are missing.

Hi,
I have a problem with cmake not to compile but to link my .exe.
I use SDL, OpenGL, FMOD, LibXml2 and a personal library. But when I try to
compile my program LibXml2 and SDLmain are not include into the command line
to link my .exe.
Enclosed my CMakeList.txt and CMakeCache.txt and here the line for the
linker into build.make:
Output/shootspace.exe: C:/MinGW/lib/libSDL.dll.a
Output/shootspace.exe: C:/MinGW/lib/libfmodex.a
Output/shootspace.exe: CMakeFiles/shootspace.dir/build.make
Output/shootspace.exe: CMakeFiles/shootspace.dir/objects1.rsp
@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR)
--red --bold Linking CXX executable Output/shootspace.exe
/c/Program Files (x86)/CMake 2.8/bin/cmake.exe -E remove
-f CMakeFiles/shootspace.dir/objects.a
/C/MinGW/bin/ar.exe cr CMakeFiles/shootspace.dir/objects.a
@CMakeFiles/shootspace.dir/objects1.rsp
/C/MinGW/bin/g++.exe -Wl,--whole-archive
CMakeFiles/shootspace.dir/objects.a -Wl,--no-whole-archive -o
Output/shootspace.exe -Wl,--out-implib,Output/libshootspace.dll.a
-Wl,--major-image-version,0,--minor-image-version,0
-Lsource/lib/gtl/lib/mingw -lmingw32 /C/MinGW/lib/libSDL.dll.a -lpthread
-lglu32 -lopengl32 /C/MinGW/lib/libfmodex.a -lgtl -lkernel32 -luser32
-lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
As you can see, LibXml2 library and SDLmain library are found in
CMakeCache.txt but not include in build.make because –lxml2 and –lSDLmain
are missing.
Why ? I do something wrong in my CMakeList.txt ?
yes.
since you did
Find_Package(LibXml2 REQUIRED)
you'll have to:
target_link_libraries(
shootspace
${LIBXML2_LIBRARIES}
and not XML2_LIBRARY
in you CMakeCache.txt you'll see that SDLmain is not found.
//Path to a library.
SDLMAIN_LIBRARY:FILEPATH=SDLMAIN_LIBRARY-NOTFOUND
for SDL I suggest you read the documentation of the module:
cmake --help-module FindSDL
there are some explanation about SDLmain or not.

Re: [CMake] Impossible to link SDLmain and LibXml2
Thanks, for libXml2 it was indeed LIBXML2_LIBRARIES instead of
LIBXML2_LIBRARY. And for SDLmain it was an error in one on my change on
findSDL.cmake file because I have replaced $ENV{SDLDIR} by another
environment variable.
Thanks again at all of you :-)
Cheers.

You should use LIBXML2_LIBRARIES [1].
