Re: [Xen-devel] Inheriting CFLAGS

The modified ebuild on bugs.gentoo.org has a sed command to update the Rules.mk file to inherit the cflags that you set in make.conf

Is all go now (YAY!)

It looks like the ebuild changed the last line above to that (I assume
your CFLAGS env variable is -O3 -march=pentium2 -pipe).  I didn't use
the ebuild, so I had the default line of CFLAGS  += -O3
-fomit-frame-pointer, and found that I had to add -nopie and
-fno-stack-protector to compile xen.

Perhaps -march=pentium2 fixed it for you?  Or perhaps those were just
somethings special I had to do on the crusoe?!?
