# Slackware build script for cproc
# Written by B. Watson (urchlay@slackware.uk)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# Note: thought about including mcpp (either in this build
# or a separate one) so cproc wouldn't have to use gcc's
# preprocessor. There even used to be a development/mcpp
# SlackBuild... for Slackware 12.1 (in 2010).
# However, mcpp looks to be old and unmaintained upstream, and cproc
# doesn't seem to support using it (would require patching, not gonna
# do).

# cproc needs to know the location of the ELF "interpreter" (the

# and a binutils for the target platform. Not gonna spend time on
