Bug 75518 – xine-lib-1_rc8-r1 compile fails - can't find register in class `BREG' while reloading `asm'

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Scott Marks 2004-12-23 21:56:46 UTC]

As far as I can tell, this is *NOT* the -fpic/-fPIC conflict problem.  I have tried various combinations, including commenting out CFLAGS completely from make.conf.

This is the complete emerge transcript.

[Comment 2 Seemant Kulleen (RETIRED) 2004-12-23 22:45:46 UTC]

it's your CFLAGS that are causing this.  For starters, remove -fPIC from that.  Please don't use CFLAGS that you do not understand.

[Comment 3 Scott Marks 2005-01-03 13:32:27 UTC]

Perhaps you ought to read the Description a little more closely.  Did you miss this?
"As far as I can tell, this is *NOT* the -fpic/-fPIC conflict problem.  I have tried various combinations, including commenting out CFLAGS completely from make.conf"

However, subsequent work on xine-lib-1.0 seems to make the issue moot.  A different change evoked a bug in the libcaca ebuild, but that is definitely a distinct issue.

Insofar as your somewhat rude comment "Please don't use CFLAGS that you do not understand" goes, I have been building position-independent executables since 1975, and have been a occasional contributor to gcc since 2001.  In this particular case, I was led to use -fPIC by the Gentoo Linux Prelink Guide:
