After building samplecat from the 0.3.0 tarball I get a segfault when running it

Thanks for the backtrace. You hit some dodgy old code there, probably referencing a widget that was not instantiated. I am hopeful that the commit mentioned above fixes the problem for you Regards

simonvanderveldt commented 4 years ago

Just tried to build from git but the libwaveform submodule is using a very old commit (this one to be precise https://github.com/ayyi/libwaveform/commit/11b08878daebd3753d5281d18aa305444fc50e2d) causing the build to fail (specifically because waveform/promise.h is missing). I've updated the submodule to current master, which is this commit at the moment https://github.com/ayyi/libwaveform/commit/17b4fe92adad11dd0fa92b969b1890767c7f1d9d. Compilation worked after that. I'm not sure that's the branch that should be used, but the submodule should definitely be updated :)

Anyway, the segfault is gone now :) Thanks for the quick fix! Unfortunately I did run into a bunch of other issues. Should I create separate issues for them?

Hi

Yes the master branch is the best branch. As it says in the README you do have to do

git submodule foreach git pull origin master

but I don't know why this is needed.

Glad the segfault is fixed. Yes, separate issues per issue - please create as many as you like! Cheers
