stdout from emerge gnome to ^c

[Comment 2 Mark Guertin 2002-09-14 11:01:25 UTC]

If this is with gcc 3.2 based setup, the cflags you are using may be causeing 
the problems.  Please emerge -u portage (and make sure you update the new 
make.conf) and look at the CFLAGS examples. 
 
I suspect this may be the problem 

[Comment 3 Michael Tomkins 2002-09-15 18:28:00 UTC]

Where is :
examples of the make.conf?
a FAQ for 1.4 setup? 
(appart from this thread http://forums.gentoo.org/viewtopic.php?t=11963)
examples for gcc3.2?

should this be obvious?

[Comment 4 Mark Guertin 2002-09-17 13:38:07 UTC]

the examples are all within the latest make.conf (supplied by portage), if you
dont see them you will have to emerge help to find out how to update your conf
files.

Also that thread in the forums is very x86 centric and should not be used as
reference for ppc :)

[Comment 6 Michael Tomkins 2002-09-20 20:58:55 UTC]

Ok, read the sticky in PPC on the forums page an this has just become a know bug.

My make.conf has
CFLAGS="-02 <some flags I forget> -mcpu=604 -mmultiple -mstrings"

-mmultiple -mstrings are known to break 1.4 (according to the forums post), just 
copied them from 1.2 :(

As is seems that a release version of 1.4 is imminent and since I don't want to 
spend 8 days recompiling from scratch I will wait for a 1.4 main release.
