I tried but wasn't much of a help 😉

Hi- There is a new bug when compiling the most recent source. CMake configures and generates fine, as far as I can tell. I now encounter this error, during 'make':

[ 98%] Building CXX object mt32emu_qt/CMakeFiles/mt32emu-qt.dir/src/audiodrv/QtAudioDriver.cpp.o

Same system as before. Any help would be appreciated. Thank you for all your hard work. 😀

I have found the solution. The problem is with Xcode's version of Clang. Mt32emu-qt compiled once I specified the compilers to /usr/bin/gcc and /usr/bin/g++ in CMake. That should be a temporary solution until/if Apple fixes the bug in its version of Clang.

Funnily as you are on Lion and thus on Xcode 4.2 or 4.3x you don't actually have gcc 😉 those gcc & g++ in usr/bin are just symlinks to lvm-gcc/g++
I've run into something like that too before some time ago. You could send Apple a bug report if you are in thd developer program.

I've tried to compile this in Linux. The cmake step failed because it couldn't find PulseAudio. I deleted that from the CMakeLists.txt.

Aftet that, the build aborted because it couldn't find "asoundlib.h". I've fixed mt32emu_qt/src/audiodrv/AlsaAudioDriver.h to #include <alsa/asoundlib.h> instead.

That worked and I got a binary. I ran it, but when I select "Options->ROM Configuration", it crashes with:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted

I'm on Qt 4.8.2.
