I am not sure if this is the right place where to ask this, or maybe the "technology preview" forum: when trying to write down the set of instructions I performed for the Windows 64bit compilation ( http://musescore.org/en/node/23116 ), I noticed that in the CMakelists.txt for most of the folders constituting MuseScore source files there are these lines, or similar ones: set_target_properties (<name of the library> PROPERTIES COMPILE_FLAGS "-g ${PCH_INCLUDE} -Wall -Wextra -Winvalid-pch" ) In particular, if I understand correctly, the "-g" option is used also in the release build, not only in the "debug" build. I was wondering if these additional "-g" flags could be skipped when not in debug build mode.
I have also another pair of questions. After some work, I managed to compile a 32bit version under 64bit Linux Mint 13. I installed the 32bit Qt package, the 32bit system libraries (ia32-libs) and cross-compile libraries (multilib). I added "-m32" to the CMAKE_CXX_FLAGS_DEBUG and CMAKE_CXX_FLAGS_RELEASE in MuseScore/CMakelists.txt. I then had problem only in the final step when mscore application is linked. I could not figure a way to force the linker to search for vorbis, ogg, sndfile libraries in the correct /usr/lib/i386-linux-gnu folder, it was saying "-lvorbis not found; -logg not found; etc." also when "-L/usr/lib/i386-linux-gnu" was used. I had to manually edit, after a first failed compilation, the generated MuseScore/build.relese/mscore/CMakeFiles/mscore.dir/link.txt and substitute all the references to the not-found libraries with the correct ones (for example, substituting "-lvorbis" with "/usr/lib/i386-linux-gnu/libvorbis.so.0") and then using the final instruction "cd /home/antonio/MuseScore_32/build.release/mscore && /usr/bin/cmake -E cmake_link_script CMakeFiles/mscore.dir/link.txt --verbose=1". First question [or, maybe better definition, feature request :-) ]: is it possible to add an environmental variable, for example "mycxxflag" or something like this, to be appended to both the CMAKE_CXX_FLAGS for release and debug (for each operating system), so that personal customization of the compile chain can be easily done (for example, cross-compilation for 32/64 bits systems with "-m32" or "-m64")? Second question: do you know how I can force, inside the cmake script used for the compilation, the linker to use libraries in custom folders? Thank you for your help.
