[comp.unix.sysv386] Magic number problems

jsantos@bubba.ma30.bull.com (Jim Santos) (10/30/90)

Hi,
	I have built gcc and gas on a 386 system running SCO Unix
V3.2.1 (using the COFF patches from tut.cis.ohio-state.edu).  I
created a little test program just to try them out.  But I get the
following output:

$ gcc -v test.c -o test
gcc version 1.37
 /usr/local/lib/gcc-cpp -v -undef -D__GNUC__ -Dunix -Di386 -D__unix__ -D__i386__
 test.c /usr/tmp/cca02086.cpp
GNU CPP version 1.37
 /usr/local/lib/gcc-cc1 /usr/tmp/cca02086.cpp -quiet -dumpbase test.c -version -
o /usr/tmp/cca02086.s
GNU C version 1.37 (80386, BSD syntax) compiled by GNU C version 1.37.1.
default target switches: -m80387
 /usr/local/lib/gcc-as -C -o test.o /usr/tmp/cca02086.s
 ld -o test /lib/crt0.o test.o /usr/local/lib/gcc-gnulib -lc /usr/local/lib/gcc-
gnulib
ld crt0.o: file test.o is of unknown type: magic number =    107

What do I need to do so that it uses the correct 'magic number'?  I
looked in the module 'coff-conv.c' where it seems to define the magic
number, but changing it there didn't seem to do me any good.  I cannot
figure out where it is coming up with '107'.  Any help would be
greatly appreciated.  Please respond via email.

The code in coff-conv.c is not being invoked, and you are getting a BSD
object rather than a coff object. This is because gas has been configured
to produce coff objects by default and BSD objects when passed the "-C"
switch. Remove the "-C" from ASM_SPEC.
