From Bugzilla Helper:

g77 is not compiling Fortran programs using redhat 7.1 that compile fine
under redhat 7.0.

Here is a sample fortran program:


      program testg77

      stop
      end


Under redhat 7.1, compilation produces the following:

[deisz@landau deisz]$ g77 -v test.f

While under Redhat 7.0, the same program compiles as 
below:

Reproducible: Always
Steps to Reproduce:
1. Try to compile on a redhat 7.1 machine
2.  Successfully compile on a redhat 7.0 machine
3.
	

Actual Results:  Doesn't compile on 7.1, will using 7.0.

Comment 1 Jakub Jelinek 2001-04-27 16:21:01 UTC
Works for me, atexit is provided by /usr/lib/libc_nonshared.a which
should be brought in by /usr/lib/libc.so linker script.
Can you a) make sure your /usr/lib/libc.so is a linker script
b) rerun the above command with -Wl,--verbose so that it is clear
what the linker is doing?

Comment 2 John Deisz 2001-04-29 18:32:51 UTC
When you pointed out the connection to libc I queried my glibc packages and got
the following:

     glibc-devel-2.2-12
     glibc-common-2.2.2-10
     glibc-2.2.2-10
     glibc-profile-2.2-12 
     compat-glibc-6.2-2.1.3.2

So, the glibc-devel package wasn't upgraded during 7.0 -> 7.1 (probably my fault
-- I'm
not sure) and the dependency of gcc-g77 on the new glibc-devel wasn't caught
somehow.

In any case, after upgrading glibc-devel by hand, compilation now works.  Thus,
my
bug report probably wasn't valid.


Comment 3 Jakub Jelinek 2001-08-09 13:03:10 UTC
Oopsie, forgot to close this. Since glibc-2.2.3-6 glibc conflicts with
glibc-devel < 2.2.3.
