#!/bin/bash
# Slackware build script for pcc (Portable C Compiler)
# Originally written by Armin Besirovic <email removed>
# Modified by B. Watson <urchlay@slackware.uk>
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# 20230108 bkw: updated for 1.2.0.DEVEL+20230108.
# 20210906 bkw:
# - updated for 1.2.0.DEVEL+20210905. Putting the .DEVEL in VERSION
# is a bit unsightly, but it matches the output of "pcc --version"
# and also Debian's version numbering scheme.
# - compiling with gcc no longer works, use clang or pcc. actually,
# compiling with gcc gives us a pcc that seems to compile stuff OK,
# but anything compiled with that pcc will segfault on startup.
# - add WTPL (since there was no license at all).
# 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
# 20150126 bkw:
# - upgraded for pcc-1.1.0 release, no more beta
# - add seddery to fix typo in cc.c (ifdef => ifndef)
# Note to self: when updating to a new CVS snapshot, first download
# the latest: http://pcc.ludd.ltu.se/ftp/pub/pcc/pcc-current.tgz Then
# look at the file DATESTAMP inside that tarball, and use that date's
# snapshot. This is because the CVS snap tarballs are generated
# nightly, whether or not there actually were any code changes,
# and we want VERSION to be the date of the last actual code change.
# For pcc-libs, just use the same snapshot date as pcc.
