[SOLVED] HowTo Rebuild GLib with debug symbols?

lancsuk · 12-26-2020, 04:32 PM

Hiya,

I have some issues with vala-panel-appmenu, and for debugging I need glib2 with debug symbols. How I can enable the symbols?

Code:

--enable-debug=yes

does not work, and I can't find any info in the meson_options file.

the default buildtype in meson.build seems to be "debugoptimized" but you can also specify an explicit "debug".
also you might want to delete the stripping routine, because symbols might be useful for you.
so in the end, IMHO, you can modify glib2.SlackBuild like this
