[Audacity-devel] Audacity, developmental glib, and wxGTK

[Ryan H. <dir...@ge...>]

Developmental versions of glib (2.21+) introduce a GSocket struct that
conflicts with GSocket in wxGTK's src/unix/gsocket.cpp [1].  This was fixed
in wxGTK with this [2] patch.

On a system that has developmental versions of glib and wxGTK-2.8,
audacity-1.3.8 will fail to build with this error:

Fedora has patched their copy of audacity like so [3], and I'm planning on
applying the same patch to Gentoo's ebuild.

I just thought I'd bring this to your attention as I haven't seen it
mentioned on this list.

Thanks.
