during build glibc-2.8 for i486-gnu-linux target i get following linker error:

note, that previous version (2.19.51.0.1) works fine.

This command is broken and has already been fixed in the glibc repository.
Comment 2 Gary Greene 2009-03-23 01:51:50 UTC 
With GLibC 2.9 snapshot 20090316 I still get the same error using binutils 2.19.51.0.2.

Error output below:

Comment 3 Alan Modra 2009-03-23 04:14:10 UTC 
This is not a ld bug, it is a glibc one.  I believe Adreas when he says it has
been fixed, but to be sure I checked the glibc source and indeed it has been fixed.
Comment 4 Gary Greene 2009-03-23 05:19:18 UTC 
I'm using the snapshot from the 16th for glibc and I just grabbed binutils 2.19.51.0.3 and I am still 
getting this. Which version of glibc are you claiming that this works on?
Comment 5 Alan Modra 2009-03-23 08:52:15 UTC 
Anything with the following patch:

2009-01-29  Andrew Stubbs  <ams@codesourcery.com>

        * elf/Makefile (ld.so): Adjust the sed script to insert _begin in to
        newer linker scripts.

Current mainline CVS of course has it.
Comment 6 Ulrich Drepper 2009-04-07 18:12:01 UTC 
I don't know what you test if you see problems.  I'ts long been changed in cvs.
