mythtv compilation for maemo (Nokia N900) failing with -lGL error
Hi all,

I am trying to compile mythtv in a scratcbox for the maemo platform
but the compilation is failing. The error is

g++ -Wl,-rpath-link,/usr/lib -Wl,-O1 -Wl,-rpath,/opt/qt-4.6.0/lib

The funny thing is that i did specify no to use opengl using the
following configure options. The GL files are listed as well.

anybody knows why a -GL is being called at all?

no, you just disabled two opengl features try adding --disable-opengl

you can remove --disable-opengl-video and --disable-opengl-vsync since
they depend on opengl. --disable-ivtv, --disable-hdpvr are also not
needed since they depend on v4l

you probably want NEON enabled for the N900

Thanks, --disable-opengl is what got me past the -lGL error. I have enabled
NEON as well, but hit another compile error in libavcodec.

I understand that maemo isnt a supported platform so if this is like chasing a
dogs tail then please let me know.

The error is as follows:

I don't know much about ARM assembly, but it would look like there is some in-line assembly in the code that is not ARM instructions. That code would need to be ported to ARM instructions to compile successfully.

The Makefile will be different, it's probably more important to look
through config.mak/config.h for arm/x86 related arch issues.
