Bug 42449 – xine-lib-1_rc2 will not build, recieves all recursive error 1 after unused variables

• Status: RESOLVED DUPLICATE of bug 31243
• Product: Gentoo Linux

[Description Paul Kozik 2004-02-21 22:06:42 UTC]

Upon emerging KDE, when emerging xine-lib-1_rc2, make outputs warnings about unused variables, followed by [postprocess.lo] and [all-recursive] Error 1 and ends with *** [all] Error 2 and parallel make failed.

Reproducible: Always
Steps to Reproduce:
1.emerge kde

Actual Results:  
postprocess_template.c:2813: warning: unused variable `mbWidth'

Expected Results:  
Should have completed building

Error occurs on any CFLAG and CXXFLAG Configuration
Athon 64 based system
Gentoo-sources 2.4 kernel

[Comment 1 Dominik Stadler (RETIRED) 2004-03-09 09:15:24 UTC]

The real error seems to be:

postprocess_template.c:61: error: can't find a register in class `GENERAL_REGS'
while reloading `asm'

so there is some MMX-specific code in there that is not available on amd64. 

Have you tried the current version xine-lib_rc3-r1?

[Comment 2 Fritz 2004-03-30 17:42:18 UTC]

I am having the exact same problem on a VIA C3 (pre-nehemiah core) based system. It is supposedly fully i586 compliant.

[Comment 3 Fritz 2004-03-30 18:23:10 UTC]

I forgot to mention that the same ERROR is also recieved with xine-lib-1_rc3-r1 and xine-lib-1_rc3-r2.

[Comment 4 Caleb Tennis (RETIRED) 2004-04-28 06:56:53 UTC]

Bug 48261 is somewhat related - perhaps rc3-r3 will help?

[Comment 5 Martin Holzer (RETIRED) 2004-04-30 03:54:53 UTC]

is this still an issue ?

please paste

I too have this problem, on a P4 machine, trying to upgrade to xine-lib-1_rc4

Problem solved by adding "-O2" to CCFLAGS
