any problems with gcc 3.0/3.1 and compiling 2.4.18 on ppc?

any problems with gcc 3.0/3.1 and compiling 2.4.18 on ppc?

[Chris Friesen]

We're looking at moving to gcc 3.x for 2.4.18, and are trying to decide what
version to use.  It appears that there were some ppc-specific fixes that went in
to 3.1, and I'm not sure if they were ported back to 3.0.

Has anyone had any successes or failures using either of these versions on
2.4.18 on ppc?
Any gotchas?

Thanks,

Chris

Both 3.0.4 and the upcoming 3.1 are fine for use with the current PPC 2.4
kernels. There is only one known issue with inlined functions that take and
return 64-bit values, these may lead to extreme stack usage. A fix for this
might go into 3.1pre CVS during the next days.
After this has been decided I'll upload gcc-3.1pre RPMS and announce them.

Hello Franz,

It looks like only me that has this intermittent problem with GCC 3.x.
Building or using.
I have:-
	glibc-2.2.4-53
	binutils-2.11.90.0.29-14 and tried binutils-2.12

I was wondering whether I was the only one building GCC 3.x on apple
hardware.

What surprises me is that the  "gcc version 2.95.3 20010319 (2.95.4CVS +
prerelease/franzo/20010912)"
is stable enough to build a kernel but not gcc 3.x on my system.

Any tips on finding this intermittent problem I have with every GCC 3.x
on my 8500 ?

Regards
Andrew

Hi Chris,

I recently built the  2.4.18+patch kernel (patch details where on
http://www.penguinppc.org/) using "gcc version 2.95.3 20010319 (2.95.4
CVS + prerelease/franzo/20010912)" with out a hitch.
But my main goal is to use g++ 3.x as my default compiler to mimic GCC
3.0.2 on my solaris and linux systems I be using since November.
I tried  (http://www.suse.com/~aj/gcc30.html) and found that there seems
to be an intermittent crash with the compiler.

I also tried building many of the snap shots. My last try was
gcc-20020318.
The Intermittent crashes sometimes go a way when I retry.

I also tried downloading code sourcery's snap shots at
http://www.codesourcery.com/gcc_binary_snapshots.
The gcc-20020318 was incomplete.

Kaoru Fuki said he has "Newer binutils,glibc,gcc from cvs branch"
http://lists.linuxppc.org/linuxppc-user/200203/msg00125.html.
But his ftp seems to be down at:- ftp://sv5.linet.gr.jp/pub/PPC/

I am building on a Suse 7.3 (Mac8500 with G3 upgrade card).

I would appreciate finding other who have successfully built using GCC
3.0 on Apple Hardware. Most people seem to build it with a cross
compiler.

Regards
Andrew

Are you sure you don't have any HW problems here? I'm building the compiler
nearly daily on 2 different machines without such problems.

The build machine had some troubles, should be fixed now.

Franz,

I set the switches on my G3 card to the factory processor speed and a
setting lower on the factory cache speed and now the intermittent crash
has disappeared.

Thanks to your voice of reason.

I shall get back to building GCC 3.x and using GCC 3.0.2 to replicate my
work environment.

Regards
Andrew
