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':

1[ 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. 😀

Uh, seems you've found a bug in Xcode 😒 That's a shame...

Okay. Thank you for letting me know where the problem is.

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.

Hmm, that's not too fun in this case 🙁 Well, QtAudio seems anyway useless for Mac, I can just disable it in order not to invent horrible workarounds...

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:

1Qt has caught an exception thrown from an event handler. Throwing
2exceptions from an event handler is not supported in Qt. You must
3reimplement QApplication::notify() and catch all exceptions there.

I'm on Qt 4.8.2.

Oh, thanks.

As it reads at http://www.cmake.org/files/v2.8/CMakeChangeLog-2.8.8
...
Changes in CMake 2.8.8-rc1 (since 2.8.7)
...
FindALSA: Fix incorrect include path detection
...
The software world surely evolves 😀

I already use 2.8.8 though. I upgraded to it on Thu May 3 2012 (from the logs.)
