# 20230715 bkw: This is an ugly way to fix an issue caused by Slackware's
# SDL2_mixer package. doomretro uses SDL2_mixer's FluidSynth support for
# its music. And SDL2_mixer-2.0.4 (what's in Slackware 15.0) has a crashing
# bug: any time Mix_FreeMusic(handle) is called when the handle is using
# fluidsynth, we get a use-after-free that causes the app to segfault.
# More details, including a link to the patch I use, here:
# https://github.com/FluidSynth/fluidsynth/issues/748
# The fix, here, is to build a *static* patched SDL2_mixer for
# doomretro to link with. Lot of work, but it does fix the issue. When
# Slackware 15.1 releases, we should be able to get rid of this.

# N.B. --disable-music-mp3-mad-gpl because enabling it breaks the build,
# as we have no static libmad.a. doesn't matter, because doomretro doesn't
