All, I have a Powerbook G4 running Leopard that I want to install and run the gromacs application under Macports. I am trying to set up gromacs on a G4 powerbook 1.25 GB RAM, 60 MB Drive, I have upgraded to OS X 10.5. I am using the Darwinports installer. As instructed, I have installed XCode tools, X11 SDK. I got xmgrace to work, however, gwyddion, rasmol and gromacs error on compilation. For gromacs, I get the following error: ---> Building gromacs with target all

The response I got back from the Gromacs help site was: This may mean that you have to change some compiler flags, since Leopard comes with a new version of gcc. Previously one had to use -faltive. Maybe you can read the gcc manual (man gcc) and the rerun make CFLAGS="-faltivec" or similar new flags. But I cannot find the right options right now. Has anyone had a similar experience? How did you address this. I am a novice to Macports. Is this the case that I need to compile with altivec? If so, how do I change the CFLAGS ? -- Carl E.
