Hello,
I am trying to install erlang on a hardened amd64 gentoo system running
on a kvm guest. The use flags and version of erlang are the following:
dev-lang/erlang-15.2 USE="hipe java kpoll odbc smp ssl -compat-ethread
-doc -emacs -halfword -sctp -tk -wxwidgets"
my CFLAGS are:
CFLAGS="-march=core2 -O2 -pipe"
CXXFLAGS="${CFLAGS}"

Emerging erlang on my desktop(a similar hardened gentoo setup) completes
successfully. The only thing I can think of is that something is wrong
with my CFLAGS(but this is just an assumption).
Any help would be appreciated

It seems that KVM host is and AMD-based system. I suggest you to drop
"-march=core2" from CFLAGS. Or if you do not plan to migrate this VM
you can also try to replace it with something like "-march=amdfam10
-mno-3dnow". :)
I thought so... I now have to rebuild the whole world :) Is anyone aware
of an -march value that can be used interchangeably between 64bit intel
& amd cpus? The kvm host is not under my administration, so at any time
my guest could be switched between hosts.
Simply do not use -march:
CFLAGS="-O2 -pipe"
Binaries compiled with this cflags should work on any x86_64 system.
Thanks. I will go with it.
