When I do this, gfortran ends up being invoked with "-arch x86_64", which isn't valid for the compiler. There are some OS X fortran compilers for which "-arch" *is* appropriate. Apparently Apple used to maintain a port of gfortran for which that flag was valid, but they seem to not do that any longer. "-arch" is also valid for the Intel fortran compiler on OS X. The problem is that the stock GCC fortran compiler does not support "-arch". Here's what a gfortran developer told me: "The GCC option for specifying an architecture is of the form '-march=XYZ' where you can a complete list of XYZ in the GCC manual. http://gcc.gnu.org/onlinedocs/gcc-4.5.1/gcc/ " ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2010-12-18 10:57 Christian ConveyNew Issue ====================================================================== _______________________________________________ cmake-developers mailing list [email protected] http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
