Comment 2 Mart Raudsepp gentoo-dev 2020-07-29 19:09:18 UTC
This suggests a glib problem that would be applicable to many glib/gtk consuming packages.

To workaround the build failure of gtksourceview one can drop -Werror=incompatible-pointer-types to get past build failure. Attached example gtksourceview-4.6.1-workaround-gcc-11.patch patch.
Comment 4 Geoff Leach 2020-12-07 13:02:04 UTC
Thanks. -Werror=incompatible-pointer-types worked for me for sysprof-capture-3.36.0-r1 gcc-11.

    x11-libs/gtksourceview: Add patch to build with GCC-11
    I mistakenly thought this patch was included in the v4.8.1 release when
    I added it and closed bug #732784.
