Build problems on Debian 10

Etnaz · August 25, 2019, 1:57pm

Hi, I am able to build Audacity (git and v2.3.2) on Debian 10 but they will not launch successfully; they will always segfault on launch.

Build config is as follow:

WX_CONFIG=/home/etna/Runtime/Applications/WxWidgetsGTK3NoInstall/wxWidgets-3.1.1/buildGTK3/wx-config LIBRARY_PATH=/home/etna/Runtime/lib:/home/etna/Runtime/lib64:$LIBRARY_PATH C_INCLUDE_PATH=/home/etna/Runtime/include:$C_INCLUDE_PATH CPLUS_INCLUDE_PATH=/home/etna/Runtime/include:$CPLUS_INCLUDE_PATH LD_LIBRARY_PATH=/home/etna/Runtime/lib:/home/etna/Runtime/lib64:$LD_LIBRARY_PATH PATH=/home/etna/Runtime/bin:/home/etna/Runtime/libexec:$PATH PKG_CONFIG_PATH=/home/etna/Runtime/lib/pkgconfig:/home/etna/Runtime/lib64/pkgconfig:$PKG_CONFIG_PATH LDFLAGS='-L/home/etna/Runtime/lib -L/home/etna/Runtime/lib64' CPPFLAGS='-I/home/etna/Runtime/include' CC=/home/etna/Runtime/bin/clang CXX=/home/etna/Runtime/bin/clang++ cc=/home/etna/Runtime/bin/clang cxx=/home/etna/Runtime/bin/clang++ CFLAGS='-Wl,-rpath -Wl,/home/etna/Runtime/lib -Wl,-rpath -Wl,/home/etna/Runtime/lib64 -fPIC' CXXFLAGS='-L/home/etna/Runtime/lib -L/home/etna/Runtime/lib64 -I/home/etna/Runtime/include -Wl,-rpath -Wl,/home/etna/Runtime/lib -Wl,-rpath -Wl,/home/etna/Runtime/lib64 -fPIC' ../configure --prefix=/home/etna/Runtime/Applications/Audacity/Build25Aug2019 --enable-shared --disable-static --with-lame --with-libflac --with-libmad --with-libvorbis --without-lv2 --enable-debug

Can anyone help? I have successfully built older versions of Audacity with wxGTK3 on older distributions using the same settings.

Thank you.

Are you using some oddball sound card drivers?

Etnaz · August 27, 2019, 1:13am

Not at all. Heck, there’s nothing exotic here; it’s just the typical onboard sound chip on my x399 motherboard.

But out of impulse, I tried rebuilding with the ‘–without-ffmpeg’ option and it launched properly.

And it worked when I copied the build out to a laptop which is also running Debian 10.

It’s even more boggling that there were no references to ffmpeg in the backtrace.

Try building with the option:

--disable-dynamic-loading

By default, Audacity loads LAME and FFmpeg dynamically, but many Linux distros have versions of FFmpeg that are too recent for this to work. However, if you are able to build against a more recent system version of FFmpeg and disable dynamic loading, then Audacity links to FFmpeg in the normal way.
