This fix prevents MythTV from running on any PowerPC without AltiVec
support.  This includes Macintosh G3's, which are supported by the
Ubuntu PowerPC port.

For better PowerPC coverage I would suggest this fix instead:

diff rules.orig rules
47c47
< CONFIGURE_OPTS += --enable-altivec
---
> CONFIGURE_OPTS += --disable-altivec

Alternatively a runtime test for AltiVec capabilty and dynamic loading
of AltiVec specific modules.

Status in “mythtv” package in Ubuntu: Fix Released

Bug description:
Binary package hint: mythtv

When trying to compile mythtv from the source package mythtv_0.23.0+fixes23820 under powerpc, I get the following error:

In file included from yuv2rgb.cpp:44:
/usr/lib/gcc/powerpc-linux-gnu/4.4.3/include/altivec.h:34:2: error: #error Use the "-maltivec" flag to enable PowerPC AltiVec support

To fix this I updated the debian/rules file with cxx option "-maltivec", as per:

diff rules.orig rules
47c47
<     CONFIGURE_OPTS += --enable-altivec
---
>     CONFIGURE_OPTS += --enable-altivec --extra-cxxflags="-maltivec"

After this fix mythtv builds cleanly under powerpc
