# uqm uses a custom build.sh to configure and build the source.
# It's not a bad system, but it's interactive only, meaning I have
# to script answers to the build.sh prompts, hence build_config().

# WARNING: If you're updating this SlackBuild for a new version of
# uqm, check and make sure the build.sh options haven't changed!

# It'd be more efficient to require a system-wide libmikmod instead of
# using the included (statically linked) one, but it's not that big
# a library, and this way we don't have any external dependencies.

   echo 2     # Top-level menu option 2: OpenGL support...
   echo 2     # 1 = Don't include, 2 = Include OpenGL graphics support
   echo 4     # Top-level menu option 4: Tracker music support
   echo 1     # 1 = included libmikmod, 2 = system libmikmod
   echo 10    # Top-level menu option 10: Installation paths...
   echo 1     # Option 1 = Installation prefix
   echo /usr  # New value:
   echo 3     # Option 3 = Location for non-sharable data
