Steve et al,
# So would the following form a better set of instructions for the port
# (given the above patch is merged)?
Might not, because...
# 1. don't follow the instructions about changing your PATH and setting
# CCACHE_PATH in /etc/profile or cshrc
# 2. use the following in /etc/make.conf
#
# .if !defined(NOCCACHE)
# .if ${.CURDIR:M/usr/src*}
...I'm not sure whether the CURDIR always is under /usr/src;
it might change to somewhere under /usr/obj. Haven't investigated, though.
# CC=CCACHE_NOHASH_SIZE_MTIME=y /usr/local/bin/ccache cc
# CXX=CCACHE_NOHASH_SIZE_MTIME=y /usr/local/bin/ccache c++
# .else
# CC=/usr/local/bin/ccache cc
# CXX=/usr/local/bin/ccache c++
# .endif
# .endif
#
# (untested though)
I would simply not mess with make.conf and obfuscated .CURDIR magic, but
rather write a little and obvious shell script "build-sys" along
#!/bin/sh
set -e
unset CCACHE_PATH # Make ccache search PATH for the real compilers.
CC="/usr/local/bin/ccache cc" CXX="/usr/local/bin/ccache c++"
export CCACHE_NOHASH_SIZE_MTIME=yes
cd /usr/src
make CC="${CC}" CXX="${CXX}" buildworld
make CC="${CC}" CXX="${CXX}" buildkernel
Does this work for you? BTW, you can always disable ccache with
export CCACHE_DISABLE=yes.
Regards,
Jens
