Optional Dependencies
|
|
=====================
|
|
|
|
jack - if you want to use JACK for audio output, install jack and set
|
|
JACK=yes in the environment before building xroar. If JACK audio has
|
|
x-runs, try 'setcap cap_ipc_lock,cap_sys_nice=ep /usr/games/xroar'.
|
|
|
|
|
|
Environment Variables
|
|
=====================
|
|
|
|
GTKGLEXT - If you have gtkglext installed, but don't want to build
|
|
xroar with it, export GTKGLEXT=no [1] [2].
|
|
|
|
SDL2 - If you don't want to build xroar with SDL2, export SDL2=no [2].
|
|
This will remove the "-ui sdl" option, which is probably of no
|
|
consequence since the SDL user interface isn't very featureful.
|
|
|
|
OSS - use OSS for audio? Default is "no", export OSS="yes" to enable.
|
|
Most users won't need this.
|
|
|
|
PULSE - use PulseAudio? Default is "yes", export PULSE="no" to disable.
|

Notes
|
|
=====
|
|
|
|
[1]: Yes, gtkglext is optional, despite being listed in REQUIRES in
|
|
the .info file. I made it a hard dependency because the SDL user
|
|
interface has no real GUI features, while the gtkglext UI acts
|
|
like a proper GUI application. Users who just take the defaults
|
|
will end up with the usable UI. If you're reading this, you're
|
|
welcome to ignore the REQUIRES="gtkglext" and build with SDL2
|
|
only, if you have a reason to want to.
|
|
|
|
[2]: At least one of SDL2 or gtkglext is required, so you can't build
|
|
with SDL2=no GTKGLEXT=no. If you want to be super-pedantic, yes,
|
|
it *is* possible to build xroar without either gtkglext or SDL2,
|
|
but the result is that xroar won't display anything at all. This
|
|
is useless and confusing, nobody wants it, and I'm not willing to
|
|
support it.
