[Spice_discussion] Compiling SPICE software with gfortran

[William Thompson]

I've solved this problem.  Evidently in Mac OSX you have to tell where to find 
the libraries.  I was able to get it to compile with the following command:

gfortran -C -o cksmooth cksmooth.f -m32 -mmacosx-version-min=10.5 \
         -L /Developer/SDKS/MacOSX10.5.sdk/usr/lib \
         support.a spicelib.a
