erlang fails to install on kvm guest (illegal instruction)

Nov 20, 2012, 6:54 AM

Post #1 of 6 (3196 views)

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}"

cat /proc/cpuinfo reports 4 cores of:

processor : 3
vendor_id : AuthenticAMD
cpu family : 6
model : 2
model name : QEMU Virtual CPU version 1.0
stepping : 3
microcode : 0x1000065
cpu MHz : 2100.278
cache size : 512 KB
fpu : yes
fpu_exception : yes
cpuid level : 4
wp : yes

pat pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 popcnt
hypervisor lahf_lm svm abm sse4a
bogomips : 4200.55
TLB size : 1024 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management:

the error message that emerge prints while dying:

And finally, dmesg reports:

in beam.smp[54b48e4000+261000]

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

Yannis

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.
