Ticket #8263: Mythfrontend 0.22-fixes Crashes on Startup 'Illegal instruction'
#8263: Mythfrontend 0.22-fixes Crashes on Startup 'Illegal instruction'
------------------------------+---------------------------------------------

------------------------------+---------------------------------------------
I get an 'illegal instruction' error after compiling mythtv-022-fixes from
svn. The computer is a PPC, G3 iBook running Linux.

I used the following incantation to build the main programs.
./configure --prefix=/usr --tune=G3 --arch=ppc --enable-libfaad
--disable-hdhomerun --disable-mmx --disable-mmx2
--disable-amd3dnow --disable-amd3dnowext --disable-altivec --enable-
nonfree --enable-gpl

I probably applied the 'sophmore principle' to the configure options.

See attached debug file.

Comment:

These configure options are horrifying-- please try with *just* --enable-
proc-opts, and NONE of the other stuff besides prefix.

Comment(by mpapet@…):

Well, it would be nice if I didn't need those options to get it to build,
but it took me a while to get to a consistent build. Also, it's a slow
machine and never will run as a backend, so I turned off some stuff.

./configure --enable-proc-opt

Comment:

Janne, don't know if there's any point in trying to do proc-opts for such
an ancient processor, but passing to you, feel free to unassign as
necessary.

Comment(by mpapet@…):

I did a distclean before rebuilding mythtv per the new spec. Same illegal
instruction error.

I discovered that if the client can't log into the database, the client
config comes up and works as expected.

When I change permissions on the MySQL backend to allow the g3 iBook, I
get the illegal instruction error.

Comment:

I'm not going to fix this for 0.22 without access to hardware.

./configure --prefix=/usr --cpu=g3 --enable-libfaad
--disable-hdhomerun --enable-gpl

might be worth a try or if you want to try 0.23-rc --cpu=host

Comment(by mpapet@…):

If it's the case you aren't interested in working on an old release, then
just say so and close the bug. I'll start over with whatever version you
would like me to work with. Whatever is most interesting to you works for
me.

If you want to work on 0.22, I can give you access to the iBook via a hop
from a public-facing ssh account. Will that work for you? My email
address should be associated with this bug. I'll send you credentials
directly.

Comment(by anonymous):

On 0-22-fixes, disabling altivec returns the below build error. In plain
english it looks like mythtranscode doesn't know about the --disable-
altivec flag. Other than that, I'm out of my league.

I'll build the 0-23-rc2 and post those results in the next few days.

Close the bug.

I cleaned the system of every mythtv file and directory and started over.

The following incantation works for 0-22-fixes on a PPC ibook 500mhz.

./configure --prefix=/usr --cpu=G3 --arch=ppc. --prefix=/usr --enable-gpl
--disable-altivec

By 'works' I mean the bug no longer exists.

Thanks for helping me work this out.
