I am getting an error during the compile of some FORTRAN code that I
cannot quite diagnose. All of my files get through a 'f77 -c'
compilation fine (well, warnings about unused local variables aside),
but the final, linking step dies,
f77 -g -L/usr/local/lib -lU77 -lm cdbcmp.o cdflam.o cdfmix.o cdftrb.o cdpcmp.o drag.o enthal.o fnbll.o fnblt.o fnffl.o fnfft.o fnfme.o fnfp.o fnfre.o fnrgh.o fsp.o interp.o lp.o quad.o rbbody.o rbheat.o rbout.o rbrad.o rbwall.o rexbdy.o rsc.o rvbbp.o rvbcof.o rvbint.o rvbitp.o rvdlnt.o rvshok.o setpt.o sp.o tonset.o trptid.o trpttj.o -o ../rsc
rvshok.o: In function `rvshok_':
/usr3/mada/cjc/rsc/src/rvshok.f(.data+0x0): multiple definition of `_BLNK__'
rvbint.o(.data+0x0):/usr3/mada/cjc/rsc/src/rvbint.f: first defined here
*** Error code 1
Stop.
The symbol '_BLNK__' or 'BLNK' never appears in any FORTRAN source
file, but it is all over the object (.o) files (not just the ones
giving the error).
I thought this might be some byproduct of the f2c process, but when I
compile with our IRIX SGI MIPSPro F77, I get,
f77 -g -L/usr/local/lib -lU77 -lm cdbcmp.o cdflam.o cdfmix.o cdftrb.o cdpcmp.o drag.o enthal.o fnbll.o fnblt.o fnffl.o fnfft.o fnfme.o fnfp.o fnfre.o fnrgh.o fsp.o interp.o lp.o quad.o rbbody.o rbheat.o rbout.o rbrad.o rbwall.o rexbdy.o rsc.o rvbbp.o rvbcof.o rvbint.o rvbitp.o rvdlnt.o rvshok.o setpt.o sp.o tonset.o trptid.o trpttj.o -o ../rsc
ld:
Warning: rvshok.o: _BLNK__: multiply defined
previous (used) definition from 'rvbint.o';
new (ignored) definition from 'rvshok.o'
So this seems to be something that occurs across platforms.
What is causing something like this? How can I fix it, can it be
fixed, at the source level? Can I coax the FreeBSD f77 to ignore the
problem and build code anyway? Or will this likely result in broken
code (and therefore is my IRIX executable probably untrustworthy)?
I am by no means a FORTRAN guru (them is a scary bunch), so any hints
would be appreciated. Thanks.
