Please Help!, Need to test glibc 2.1.3 with these additional patches under 2.3 kernels

Please Help!, Need to test glibc 2.1.3 with these additional patches under 2.3 kernels

[Kevin Hendricks]

Hi,

glibc 2.1.3 is just about to go *final*

BUT...If we want glibc 2.1.3 to compile out of the box under PPC under 2.3.XX
kernels and actually work we really need people running 2.3.XX kernels to grab
the source from glibc cvs and apply the following patch and test this thing
asap and report some results.

please note, glibc 2.1.3 is now very *stable* under 2.2.X kernels with lots of
bug fixes and things.

The key issue here is finding out whether glibc 2.1.3 will compile and run
under 2.3.XX kernels.

If you are willing to help, please let me know and give this a try.

They will *not* hold up the release just for us, so your help and feedback would
be greatly appreciated.

Thanks,

Kevin

I'm appending a complete patch (ftruncate64 and truncate64 need
updating from glibc 2.2 also) which includes Joel's patch.

Ulrich, please apply this to 2.1.3.

This is should solve all problems with Linux 2.3.

Could one of the powerpc users double check that this patch works fine
with Linux 2.3 and send some feedback?

Thanks,
Andreas

Thanks!

First, login to cvs server
enter "anoncvs" as the password:

   cvs -z4 -d :pserver:anoncvs@anoncvs.cygnus.com:/cvs/glibc login


Then to check out the 2.1 branch of the source tree:

   cvs -z4 -d :pserver:anoncvs@anoncvs.cygnus.com:/cvs/glibc co \
   -r glibc-2-1-branch libc


Or, if it is easier, I have put a tar gzip archive of yesterday's CVS tree on
my ftp server:

ftp://khendricks.ivey.uwo.ca/pub/
