I don't use KDE but that kind of struck me as odd, is this a known bug or is it just a bad experience your speaking of personally?

Known bug in Noatun, hopefully it will be fixed soon. |

I just edited the ebuild to:
export CFLAGS="-march=athlon-tbird -O2 -pipe"
export CXXFLAGS=$CFLAGS
That way I don't have to compile it two times in a row. |
You wouldn't have to compile anything twice anyway. CXXFLAGS is for C++ code, CFLAGS is for C sourcecode.
If explicitly stating the CXXFLAGS did, for some reason, force anything to be compiled twice, setting CXXFLAGS to $CFLAGS would do the same thing because $CFLAGS is expanded to the exact same thing.
Or did you mean that you wouldn't need to type the flags twice? It is indeed handy for that.

just for the hell of it. oh QT3 still being compiled with -O3 |
I'm not sure if it's a typo or if the flag has been changed in GCC3, but at least in GCC2 that "-falign-functions=4" should be "-malign-functions=4" (the difference being the first letter)
Otherwise, GCC will probably complain.

no no, malign-functions in obsolete in GCC3.1 so falign-functions is used as a replacement. |

This is correct pacman:
| Code: |
CHOST="i686-pc-linux-gnu"
CFLAGS="-mcpu=i686 -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-mcpu=i686 -O3 -pipe -fomit-frame-pointer"
|
And if you want to recompile your entire system do the following:
| Code: |
emerge gentoolkit #only if you dont currently have it
qpkg -nc -I | sort | uniq | NOCOLOR=true xargs emerge 2>&1 >qpkg-make.log |
|
Well, I did it, finally my computer finished to re-compile and I DON'T feel any changes or more speed

| Posted: Fri Jun 28, 2002 8:57 pm Post subject: Additional question for Tbird people |
|
|
So, I have an AMD tbird 1.33 GHz...
Is it sort of safe to emerge gcc3? Do I have to do anything special to start using it? Do I have to unmerge gcc2.95.?
After that one...
If I change my optimizations to
CFLAGS="-march-athlon-tbird -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-march-athlon-tbird -O3 -pipe -fomit-frame-pointer"
what should my CHOST be? should it still read
CHOST="i686-pc-linux-gnu"?
And if all this is successful, I can recompile my entire existing system with emerge -e world? It won't need to access anything off the ibiblio server (and its kin) will it?
Thanks for your keen advice.

Leave your CHOST as it is, and if you still have all the source for your system in /usr/portage/distfiles then you won't have to download anything by running emerge -e world.
Would be safer IMO to just install from the gcc3 based 1.3 iso.

What 1.3 iso?
Do you mean it would be easier than trying to incorporate gcc3 on this machine?
And can I use those flags if I keep using gcc2.95.?
Thanks.

Well you can find the 1.3a iso here but you can emerge gcc3 and rebuild your system depending on the software installed some things will may fail, and no you cannot use that march flag with gcc2.

Okay, thanks a bunch... I'm gonna go download and burn that iso.
Perhaps I'll have good luck... perhaps not. We shall see.

 U boys wanna see eome TBird flags that work, well here ya go
CFLAGS="-march=athlon-tbird -O3 -pipe -fomit-frame-pointer -funroll-loops -fexpensive-optimizations -mmmx -m3dnow
CXXFLAGS=$CFLAGS
with these flags I've never had a problem compiling because of the flags, now because I'm using gcc3.1 is another topic entirely

I run KDE and Noatun from CVS head, compiled everything with frame-pointer-omitting and I don't expirience any crahes with Noatun (I use this app quite intensely). So it seems to be already fixed.
Cheers,

Is this true for Gentoo 1.2 or only for 1.3 beta? As your CPU optimisations are not for gcc2.95, which is the one used in 1.2, I assume you are running 1.3 beta...
(I'm running 1.2)

I would say the woman!
Waht Falgs would you suggest for a Athlon XP system? I took the "default" value for i686 (I just uncommented the lines in). Is it OK just to take "athlon-tbird"? |

Depends on what gcc version your using.

It shouldn't matter as long as you 'emerge rsync' and 'emerge portage' before you begin you will have the latest version of portage.
You can use -march-athlon-xp if you have gcc 3.1. Otherwise, you should probably use the i686 flag. If you want to know more look here.

this might be a different problem. checkout the xfree logs, see if you're using the correct driver for your video card for instance...

This was a rather old problem that surely has been resolved now, if I remember correctly it was kernel related.
