Each package management system is going to have its own way to specify CFLAGS and CXXFLAGS. DarwinPorts uses its own configuration file, which should really not be messed with. A lot of the ports on DarwinPorts break when using non-standard CFLAGS. Having used to work there, I know that the DarwinPorts team is very supportive and helpful; you may want to ask them about non-standard CFLAGS.

Guys, I found your site whilst searching for a way to enable G5 specific options on my IMAC. I come from FreeBSD and am used to setting CFLAGS in /etc/make.conf. Can someone please assist me. I am using Darwin Ports and wish to build all of the ports with -fast option so that I can get the most out of my Imac.

Thanks guys,

The -fast flag defaults to G5 optimisations; however, it’s smart enough not to use non-applicable flags if used in conjunction with “-mtune=G4 -mcpu=G4″ (or “-mtune=G3 -mcpu=G4″ too, I suppose). This is covered in Apple’s GCC release notes (under “Optimisation”) — and has been available since gcc3.3 iirc.

Hope this saves you a few lines of CFLAG options…

Yup. Fixing permissions fixed it. Thanks!

Permissions differ on ./usr/share/info/dir, should be -r–r–r– , they are -rw-r–r–

Well, if I had a G5, I'd be using -fast... That's even more CFLAGS; appearances can be deceiving.

Now that’s strange. Take a look at the trackbacked post (the trackback right above your comment). The solution, at least for me, was to run Disk Utility’s ‘repair permissions’. I’ll have to look into the -lgcc when I get more time. Please keep me posted on anything you find.

Switching readline’s Makefile to use -lgcc doesn’t seem to work:

( cd shlib ; make all )
rm -f libreadline.4.3.dylib
/usr/bin/libtool -dynamic -arch_only `/usr/bin/arch` -install_name /usr/lib/libreadline.4.3.dylib -current_version 4.3 -compatibility_version 4 -v -o libreadline.4.3.dylib readline.so vi_mode.so funmap.so keymaps.so parens.so search.so rltty.so complete.so bind.so isearch.so display.so signals.so util.so kill.so undo.so macro.so input.so callback.so terminal.so text.so nls.so misc.so xmalloc.so history.so histexpand.so histfile.so histsearch.so shell.so mbutil.so tilde.so compat.so -lSystem -lncurses -lgcc
/usr/bin/libtool: can’t locate file for: -lgcc
/usr/bin/libtool: file: -lgcc is not an object file (not allowed in a library)

Any idea what the long term answer will be?
