GCC runs on my 386BSD box as well as on my SCO UNIX SYSV/386 3.2r2.0 ODT 1.1 box. GCC apparently generates code in two formats -- COFF and something else. GCC utilities (ld?) appear to be capable of dealing with COFF and something else -- but this may be a compile time option. GCC on my SCO box seems to be able to link to SCO's libm.a with no problem. GCC on my 386BSD-01 box seems to be unhappy with the SCO libm.a format. So, (1) could someone post some brief description of the two GCC formats and the formats generated by ATT/SCO rcc (pcc) and cc (microsoft's cc). Why the differences? Do some tools exist to convert between these formats? For the purpose of testing/benchmarking BRLCAD on 386BSD, is there some way to convert an extra copy of SCO's libm.a (I have a full copy of the SCO ODT 1.1 development system sitting on a shelf -- not installed anywhere -- full license numbers available if someone from SCO gets concerned) to run on the 386BSD system -- so the routines from SCO's libm.a could be linked into the BRLCAD benchmark code and run under 386BSD-0.1? ------------------------------------------------------------------------------ Alexander-James Annala Principal Investigator Neuroscience Image Analysis Network HEDCO Neuroscience Building, Fifth Floor University of Southern California University Park Los Angeles, CA 90089-2520 ------------------------------------------------------------------------------
