Unless I'm misunderstanding something, the above page refers to making ATLAS run on ARM CPU's, not on the c64x+ DSP co-processor. GFortran should run fine on ARM; Android/ARM reportedly works, and for a more conventional GNU-based userland such as provided by Linux distros there should be no problem. Wrt. the c64x+, as of the GCC 4.7 release GCC supports it, see http://gcc.gnu.org/gcc-4.7/changes.html . That being said, GFortran has a runtime support library (libgfortran) which needs quite a lot of functionality from the underlying OS, so I'm sceptical that one would be able to make that work on a DSP co-processor. You might be able to avoid using the library if you use a limited subset of Fortran, e.g. no I/O, many intrinsics also need the library. There might still be problems if C6X has weird integer and/or float modes ( http://gcc.gnu.org/onlinedocs/gccint/Machine-Modes.html ) compared to "traditional" architectures; I guess you can try and see how far you get. I'm cc'ing the gcc-help list in case somebody there knows more about C6X. Good luck! -- Janne Blomqvist
