# Slackware build script for trs80gp

# Note: I found no way to use this emulator without PulseAudio. This
# is only a problem for holdouts like me, who hate pulse and
# actively avoid using it. apulse won't work (it doesn't supply
# libpulsecommon-*.so), and the emulator will segfault at startup if
# it can't use pulse. The only workaround is to run "trs80gp -sx", but
# that disables *all* audio, which is not really ideal. Closed source,
# so no patching.
# Dirt hack alert!
#
# The 32-bit x86 binary actually runs fine on Slackware 14.2. But on 15.0,
# it crahes on startup:
#
# trs80gp: cairo-surface.c:1817: cairo_surface_set_device_scale: Assertion `status == CAIRO_STATUS_SUCCESS' failed.
#
# To make it run on 15.0, use the cairo shared libs from 14.2. Amazingly,
# this actually works!
#
# So on i?86, /usr/games/trs80gp is a wrapper script that execs the
# real binary with the old cairo libs preloaded. On all other arches,
# /usr/games/trs80gp is the real binary.
