Do you have a problem with g77 and redhat 6.0 ???
Here is a bug about g77 : as I try to run a very simple and short program
(essai.f) , g77 tells me:
/usr/bin/ld : cannot open crt1.o: Aucun fichier ou répertoire de ce type
collect2: ld returned 1 exit status
My version is : redhat 6.0
Linux 2.2.5-22 #1 Wed Jun 2 09:02:27 EDT 1999 i586 unknown
This file is really needed, and it is not part of gcc , so I have copied
the missing files in the right place in the right directory
:/usr/i386-redhat-linux/lib...
and now g77 tells me :/usr/bin/ld: cannot open -lm: Aucun fichier ou
répertoire de ce type
collect2:
ld returned 1 exit status
So my question is: what do you think about it , and do you think it as
anything to do with the specs file (see part 3
)
PART1 ===> essai.f
PART2 ===> g77 -v essai.f
PART3 ===> /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
