Bug 121038

I installed FreeBSD 6.3 on a "VIA EPIA EK 8000EG" motherboard (which has a CPU integrated into it).

When I ran the command "cat /var/log/dmesg.today | grep CPU", I got the response...

CPU: VIA C3 Nehemiah+RNG+AES (800.03-MHz 686-class CPU)

I setup some /etc/make.conf parameters and recompiled both world and the GENERIC kernel.  I  installed them both.  When I then attempted to install several different packages from ports, they all kept failing.  After some investigation, it was found that setting CFLAGS=-O0 in the /etc/make.conf file allowed a successful compilation.

Indications suggest an optimisation incompatibility with the VIA CPU.

Fix: Setting CFLAGS=-O0 in the /etc/make.conf allows successful install or ports packages.

Patch attached with submission follows:
How-To-Repeat: Installed FreeBSD 6.3

I cvsup'd (src-all and ports-all tag=., RELENG_6_3).

I set /etc/make.conf parameters...

CPUTYPE=c3
CFLAGS= -O2 -pipe
COPTFLAGS= -O -pipe

I then rebuilt world and the GENERIC kernel, and installed them both.

I then attempted to install various packages from the ports system and I failed again and again.

I usually use portupgrade, so I tried the following...

cd /usr/ports/ports-mgmt/portupgrade
make install clean

As part of the install, it tried to install lang/ruby18, but it failed.
This is the error I was presented with...

of the failure of your make command. Also, it might be a good idea to
provide
an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).

I then commented out everything in the /etc/make.conf file, but the compiles still failed.

Following a suggestion in freebsd-questions, I set CFLAGS to "-pipe -O0 # letter o followed by zero digit".

Compilation (and overall install of the packages) succeeded.

Perhaps an optimisation bug on the VIA CPU?
