    compiling error -f68881

    Hi I am trying to compile a c code. I installed the extra x files from the mac install disc. This is my makefile:

    segy2sac: segy2sac.o
    cc -g -f68881 -o segy2sac segy2sac.o
    segy2sac.o: segy2sac.c
    cc -g -f68881 -c segy2sac.c

    and the error that I get is this:

    gcc -g -f68881 -c segy2sac.c
    cc1: error: unrecognized command line option "-f68881"
    make: *** [segy2sac.o] Error 1

    Can anyone tell me what this means and how to fix it? Would really appreciate it!

    Code:
    $ gcc -v
    Using built-in specs.
    Target: i486-linux-gnu
    
    What does yours say?

    The 68881 was the numeric co-processor of the 68K, which was the processor of choice for ancient Mac's.

    Since you probably don't have one of those, perhaps you could just delete "-f68881" from your makefiles.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
