RE: [gentoo-alpha] ebuild update for Xorg-x11

[Brian Parkhurst]

I've seen the issues with mieee I'll add to my default CFLAGS, might want to
add that to the Alpha Handbook Documentation.  I've seen the ieee problem
mostly with the native compaq compiler though, both on Alpha-linux and
Tru64.

I'll see if I can find the pages referencing the PIC problems again, took me
a while to find it.
 1)	http://lists.debian.org/debian-x/2003/02/msg00005.html
 2)

 3)	http://archives.neohapsis.com/archives/linux/axp/2002-q1/0397.html

Hmm, can't find the reference to PIC again but did find the above references
to a patch for the ELF relocate problem for the Xserver module loader on the
Alpha platform..

I'm running xorg-x11-6.8 on XP1000 with no problems without needing to
explicitly specify -fPIC

Oh, really?  I wasn't aware of that.  Could you point to the pages?

This isn't related to -fPIC.  I include -mieee in CFLAGS on alpha
which would probably fix that problem for you.  (I'd like it if
everybody would include -mieee in CFLAGS on alpha... there's almost no
code out there that's written to work with the non-ieee behavior, so
it's just asking for trouble to build without it)

Good to hear it's working...  I don't have an ATI adapter on alpha to
test at the moment.  My daily workstation has an Elsa GLoria.
