I hear you. I've spent quite a bit of time trying to get fink to respond to my environment variables.
My question to the group is this; how come fink doesn't use the CFLAGS environment variable? I tried setting it all over the place and it just doesn't seem to pick it up.
For anyone who doesn't think this is worth the effort a properly compiled lame encodes at ~1.7x instead of ~0.5x on my iBook -- 0.5x => twice the length of the song in minutes.
Cheers, Joe
To be clear I did a configure and make install of lame via the command line and got an executable that ran three times faster! All that was really required was the following:
export CFLAGS="-O3 -fomit-frame-pointer -ffast-math -funroll-loops -fno-common"
./configure --prefix=/sw --enable-mp3x --with-gtk-prefix=/sw --enable-mp3rtp --mandir=/sw/src/root-lame-3.93.1-1/sw/share/man --libexecdir=/sw/lib
make install
Of course those need to be preceeded by sudo.
I got the configure line by just running fink and watching what rolled by.
The CFLAGS are actually written in the configure file they're just not being used.

Re: lame optimizations
2003-05-19 07:12I tried SetCFLAGS, and ConfigureParams, but neither made any difference. Perhaps I also need to fiddle with one of the compiler settings for one of the dependencies.
This isn't a real big deal, as I'll just keep on using these other programs, instead of fink's lame.
