Missing symbols in debug build

groumpf

I'm trying to build my project in debug mode because release mode optimizes thing too much in my specific debugging case.

But, the build seems to have missing symbols from Bela source code :

Executing task: ../Bela/scripts/build_project.sh -n --force src -m "debug"
[...]

I tried both distclean and clean target just in case, but it didn't helped. Did I missed something in my configuration ?

the issue is that the debug build is just broken and won't be fixed.
To achieve a similar result (i.e.: disable optimisations), just rebuild with -m "CPPFLAGS=-O0 CFLAGS=-O0".

As usual, I recommend first building the project (and most importantly the core code) with the default -O3 and then only rebuild with -O0 those files you need to debug.

Ok thanks I'll try this 🙂
