g77 and gdb.

["Paulo José da Silva e Silva" <rsilva@ime.usp.br>]

Hello,

I am sure I am doing something silly, but I can´t find out what.

I can not manage to debug fotran code compiled with g77. I am using GNU
Fortran 0.5.24-19980804 (instaled from slink and part of the new egcs
1.1). Here is an exemple of what I am doing:

I try to compile the "hello world" program bellow:


hello.f:
      program hello
      print *, "Hello World!"
      end


It works well. Then I use "g77 -g hello.f -o hello" to compile it with
debbuging information. After that I start gdb with "gdb hello". Gdb
complains it can´t find a file called:
              ../../../../libf2c/libF77/main.c
Here is sample of a gdb session:


bash-2.01$ gdb hello

What am I doing wrong?

Paulo.
