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?

My guess: gcc4.4.4 had --disable-werror by default, so we must -werror explicitly to get warning treated as errors; gcc4.5.1 does NOT have --disable-werror by default, so, unless you specify --disable-werror on the compile line, warnings are treated like errors.

I don't have either compiler version here at work, so I can't verify.

ANYHOW, if your 4.5.1 build tree Makefile has CFLAGS with --disable-werrors in it, does the problem go away?

Hmm... If I understand you, then I need to rebuild gcc with this config option? - I am using the gcc that came with f14 - Is there a switch to gcc to disable this 'feature' when I am trying to build a kernel - like -fdont-treat-warnings-as-errors ;-)
