Description Bernhard Rosenkraenzer 2001-11-12 20:00:01 UTC 
octave fails to detect gcc 3.1's f77 as a compatible compiler:

checking whether g77 is the GNU Fortran compiler... yes
checking g77/f2c compatibility... no
checking for f2c... no
configure: warning: in order to build octave, you must have a compatible  
configure: warning: Fortran compiler or f2c installed and in your path.

This might be caused by a g77 bug; please verify and reassign if 
necessary.

gcc-g77-3.1-0.7

gcc bug - it can't even compile the FORTRAN version of "hello, world":
[teg@oslo teg]$ g77 -o hello hello.f
/usr/bin/ld: cannot find -lfrtbegin
collect2: ld returned 1 exit status
[teg@oslo teg]
