#
# The build rules in this file are intended for use by GAP packages that
# want to build a simple GAP kernel extensions. They are based on the
# GAP build system, and require GNU make. To use this in your GAP
# package, `include` this file from your primary Makefile. You must also
# set several variables beforehand:
#
# - GAPPATH must be set to the location of the GAP installation against
#   which to build your package.
# - KEXT_NAME should be the name of your kernel extension (without
#   file extensions like .so or .dll)
# - KEXT_SOURCES must contain a list of .c or .cc files to be linked
#   into your kernel extension
# - optionally, you can set KEXT_CFLAGS, KEXT_CXXFLAGS, KEXT_LDFLAGS
# - if you are using autoconf to produce your configure script, set
#   KEXT_USE_AUTOCONF to 1 to enable dependency rules that enable
#   regenerating the configure script etc. when necessary
#
# The contents of this file are released into the public domain; hence
# you may edit this file as you wish, bundle and distribute it with your
# package, etc.
#
# If you bundle this file with your package, please try not to edit it,
# so that we can keep it identical across all GAP packages. Instead, if
# you find that you must edit it, please submit your changes back to
# the GAP team, so that a future version of this file can be adjusted
# to cover your usecase without modifications, thus ensuring you can
# always easily update to newer version of it.
