# Slackware build script for pcc (Portable C Compiler)
# Originally written by Armin Besirovic <armin[at]linux[dot]org[dot]ba>
# Modified by B. Watson <yalhcru@gmail.com>
# 20141031 bkw:
# - took over maintentance.
# - upgraded for 1.1.0 beta series.
# - combined pcc and pcc-libs into one build, since either one is
# useless without the other.
# - removed pcc-lib's 002-build-libpcc-with-pcc.patch as it's been
# applied upstream in the 1.1.0 branch.
# - use private /usr/libexec/pcc/ dir instead of installing stuff
# directly in /usr/libexec. Probably just paranoia.
# - rename cpp-pcc man page to pcpp, since the beta installs a
# /usr/bin/pcpp.
# - get rid of -j1 in make command, seems to no longer be needed.
# - add logic to choose which compiler to use if CC not set.
# - extract license from source, install to /usr/doc
# notes:
# - pcc 1.0 hasn't worked since Slackware 13.37. It builds & installs
# fine, but anything compiled with it just segfaults in the
# startup code. Hence the upgrade to a beta snapshot, which at
# least can compile a working "hello world" on Slack 14.1.
# - upstream only keeps about a weeks' worth of snapshot tarballs, so
# so I'm self-hosting them. I do plan to update the snapshot version
# from time to time, but *not* on a weekly basis. Eventually 1.1.0
# will be released, and there will be much rejoicing.
# - upstream filenames are pcc-1.1.0.BETA-<yyyymmdd>. If you want to
# try a different snapshot, set VERSION=1.1.0_beta_<yyyymmdd> in
# the env. AFAIK, the pcc and pcc-libs snapshot dates must always
# match (this script enforces it).
