Bug 45465 – emerge mythtv does not work fails on BREG

• Status: VERIFIED FIXED
• Product: Gentoo Linux

[Description Jacob Sheck 2004-03-22 20:32:35 UTC]

When I "emerge mythtv" it fails with the error

msmpeg4.c: In function `msmpeg4_pred_dc':
msmpeg4.c:734: error: can't find a register in class `BREG' while reloading `asm'
make[2]: *** [msmpeg4.o] Error 1
make[2]: Leaving directory `/var/tmp/portage/mythfrontend-0.13/work/mythtv-0.13/libs/libavcodec'

make[1]: Leaving directory `/var/tmp/portage/mythfrontend-0.13/work/mythtv-0.13/libs'
make: *** [sub-libs] Error 2


I have tried chaing my /etc/make.conf settings includeing setting the c and cxx flags to null.  Ill attach a log of what was built.  I am using the 2.6 kernel now, and this happend with the 2.4 kernel as well.

output from emerge mythfrontend

This is the output from mythtfrontend.	Both emerge mythtv, and emerge
mythfrontend fail in the same way.  I can access this machine at almost any
time of day, any response should be responded to asap.

change your -mcpu=i686 to -march=i686 and try again, please.

Also, if you have -fPIC in your CFLAGS in make.conf, delete that bit
