Hi all,

I just finished yesterday, my new installation of Gentoo 1.4 from stage1
(with CFLAG="-march=athlon-xp -O2 -pipe -fomit-frame-pointer".
I juste finished the "emerge system", and "emerge Xfree" (no kde, no gnome,
and no optionals apps). All seems to work very well, and I was very happy.

But, I also would like to use prelink, and I just read that I need to
add -fPIC in my CFLAG and also a "pic" parameter to my "USE" variable....

So I have take a look at the book, and they say that we have to re-emerge
Xfree with those parameters activated...
Anyway, which packages are concerned ? Is it better to reinstall all ?

Tell me that it's not true.. Please... :-)) Can you give me the exact list
of what I need to rebuild (the manual doesn't tell anything about Glibc...
Hummm... it seems strange)

Thanks a lot in advance,
Olivier

I think your using some out of date info, because according to this, pic
is not even a valid use flag (any more):
http://www.gentoo.org/dyn/use-index.xml

And from what I've seen with most compiles -fPIC is added automatically.
I've been using prelink for quite some time now without either of these
options set, and no problems. You might want to check the forums about
prelinking though, I remember seeing something about some gcc version
causing unwanted effects, but if this is a fresh install, you're likely to
be safe...

"pic" is still listed as a valid flag in ufed.

Thanks for your answers !
I will retry prelink as soon as possible

Cheers,

Olivier

It's easy. Since you've got a new installation, it'll take less time. First,
add pic to your use line in /etc/make.conf file. While you're there, you
may want to look over your compiler flags too. I run some compiler tweaks
here on my athlon systems and they all run fine. Once you're done with that
file, issue an: emerge -ue world and go see a movie or two... maybe go to
bed and let the machine compile all night...

Once done, all the packages you have previously installed, will be
recompiled using the new use switch and compiler tweaks.

Uhh... before you do this, try a "man emerge" and brush up a bit.
