Hello,

I am trying to compile RHEL-6 kernel srpm on Fedora 14 and run into the
following problem. From what I read
-Werror flag causes warnings to be treated as errors - but I don't see that
flag on in the following. Any ideas?

Have you checked on the Fedora forums, or mailing list?


I googled for it. I thought that since RHEL-6 is going to soon be Centos 6 that someone on this list might know the answer. I am
only using RHEL-6 til Centos 6 is released and will have to recompile the srpm for the kernel then so I thought I would get a head
start.
