Yes, it does (as a G4 user, I specify -fast instead, which is a shortcut for a package of optimizations). gcc and cc are synonymous on my machine. The output is: > >gcc --version > powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc. > build 5367) > Copyright (C) 2005 Free Software Foundation, Inc. > This is free software; see the source for copying conditions. > There is NO > warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR > PURPOSE. > Can you give us a command line that you use for an example on how to > build on Darwin, maybe with some Darwin version info?

My own optimizations are specific to the G4. However, these optimizations encourage the compiler to take advantage of the "Altivec" technology on the chip - basically an on-board floating point math co-processor - and I would really recommend them for the G4. Variants would also need to be available for the G3, the G5, and the good old x86 set. Here's my optimizations. Note that I don't actually know for sure if any of the code in the 'Accelerate' framework libraries is being used. But what the hey, I figured. > ./build.sh --cflags="-mcpu=7450 -fast -mpim-altivec -maltivec - > mabi=altivec -ggdb3 -Wno-shadow" --ldflags="-framework Accelerate" > --make=/usr/bin/make --disable-nls --disable-socker - Matt ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
