Thread: SAC i/o routines

Hi,

I am attempting to use the SAC input/output libraries to compile a Fortran77 code for reading and filtering SAC data. I seem to be having trouble linking to the libraries:

g77 -C -ffixed-line-length-0 -I/usr/local/sac/include -L/usr/local/sac/lib -lsacio filtersac.f -o filtersac

ld: warning: in /usr/local/sac/lib/libsacio.a, file was built for unsupported file format which is not the architecture being linked (i386)
Undefined symbols:
"_rsac1_", referenced from:
_MAIN__ in cc0Tk2Cf.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I'm running OS10.6.8 on a MacBookPro, 64-bit intel core i7. Do I need to re-compile these libraries myself? If so, how do I obtain the source code?

I should note, everything else in SAC seems to be running fine, I can read/plot/write/etc.

Thanks,
