# 20180101 bkw: Update for v3.3.1. Script still works with 3.1 and 3.2,
# if you can think of a use for them.
# 20170502 bkw:
# - update for v3.2. script tested with v3.1 and still works, in case
# upstream's updated libjpegturbo API causes a problem (just get the
# old source, run with VERSION=3.1 in the env).
# - Note: ignore the 'error: ignoring unknown tag NASM' messages, per
# https://sourceforge.net/p/libjpeg-turbo/mailman/message/34381375/
# 20170310 bkw:
# - take over maintenance
# - i486 => i586
# - build static lib also
# - expand README and slack-desc
# - add JAVA=yes option
# - add API=7 and API=8 options
# - BUILD=2

# 20170310 bkw: This stuff needs documenting, or I'll forget why

# Leaving off all the --prefix and related options below, since the
# default prefix is already /opt/mozjpeg... though starting with 3.2,
# the man pages and docs are in $PREFIX/share/(man|doc), so use
# --mandir and --docdir. Also, to make 3.2 match the 3.1 package, need
# --datarootdir=$PREFIX to make the java classes go to $PREFIX/classes.
# Ryan's version of this script had --disable-static, but I'm leaving
# that off, because sometimes static libs are easier to deal with when
# you're linking with libraries outside the system /usr/lib(64) dir.
# The LDFLAGS gibberish below is to force the binaries in /opt/mozjpeg/bin
# to use the libraries in /opt/mozjpeg/lib(64), otherwise they use the
# system libjpeg in /usr/lib(64) which partly defeats the purpose of
# having optimized jpeg libs...
