Bugzilla Bug 52722

MythTV 0.15.1 was released on May 31 (0.15 was released on May 26). It adds
internal support for Zap2It TV listings. XMLTV will no longer work with it and
is not supported anymore.

Also Zap2It changed their system to fully support MythTV now, but subscribers
need a user account for free listing access and the current stable version of
XMLTV in portage does not support this.

The XMLTV developers changed the name of tv_grab_na to tv_grab_na_dd in the
more current, and supported releases as well so version 0.14 of Myth will not
work with the newer XMLTV without some major work (took me a while to get it
working properly).

Reproducible: Always
Steps to Reproduce:
1.
2.
3.

while trying to install the 0.15.1 ebuild I get the following errors:

A little more info.  I'm running xorg-x11 /usr/include/GL/glxext.h is part of
that package.  Maybe its possible that mythtv isn't compatible with xorg-x11.  

I've got the same error using xfree-4.3.0

Same error and here's an emerge info.... I've got x.org's x11.

Looks like compiling this without opengl works just fine. I put the following
in /etc/portage/package.use and was able to compile from start to end without a
hitch:

media-tv/mythtv -opengl

you could also do the following:

USE="-opengl" emerge -v mythtv

Enjoy.

Just a quick copy and paste from the header files without much analyzing.

/usr/include/GL/glxext.h - Lines 290 through 292
#ifndef GLX_ARB_get_proc_address
typedef void (*__GLXextFuncPtr)(void);
#endif

/usr/include/GL/glxext.h - Lines 373 through 386 (the offending lines


#ifdef GLX_GLXEXT_PROTOTYPES
extern __GLXextFuncPtr glXGetProcAddress (const GLubyte *);
#endif /* GLX_GLXEXT_PROTOTYPES */
typedef __GLXextFuncPtr ( * PFNGLXGETPROCADDRESSPROC) (const GLubyte *procName);
#endif

#ifndef GLX_ARB_get_proc_address
#define GLX_ARB_get_proc_address 1
#ifdef GLX_GLXEXT_PROTOTYPES
extern __GLXextFuncPtr glXGetProcAddressARB (const GLubyte *);
#endif /* GLX_GLXEXT_PROTOTYPES */
typedef __GLXextFuncPtr ( * PFNGLXGETPROCADDRESSARBPROC) (const GLubyte *procName);
#endif


A quick grep comes up with...

grep '__GLXextFuncPtr' /usr/include/GL/*
/usr/include/GL/glxext.h:typedef void (*__GLXextFuncPtr)(void);
/usr/include/GL/glxext.h:extern __GLXextFuncPtr glXGetProcAddress (const GLubyte *);
/usr/include/GL/glxext.h:typedef __GLXextFuncPtr ( * PFNGLXGETPROCADDRESSPROC) (const GLubyte *procName);
/usr/include/GL/glxext.h:extern __GLXextFuncPtr glXGetProcAddressARB (const GLubyte *);
/usr/include/GL/glxext.h:typedef __GLXextFuncPtr ( * PFNGLXGETPROCADDRESSARBPROC) (const GLubyte *procName);


What's all this mean? I dunno. I didn't look too tired and writing a paper, but I'd guess it sounds like a whoops in the headers from X.

For now...

USE="-opengl" emerge mythtv.

Oh and not to be forgotten, mythfrontend is affected too (since it's only an ebuild to install just the frotnend).

It isn't working without opengl for me too

Now I got an error about directfb:

In the version 0.15 ebuild there was a patch, but this was removed in the 0.15.1 ebuild??

I managed to get it to compile with USE="-directfb -opengl".  It took me a
while.  For some reason I kept getting compiler segfaults.  Finally I have my
mythtv running again.  Just a quick tip for those upgrading to the zap2it
service.  Make sure that you associate your input with your new source, or else
mythtv won't record any of your programs.  It took me a little while to figure
this one out.  All my recording profiles were there, but no programs were
scheduled to be recorded.

good luck to you all.

Looks like someone hit the problem on the head on the mythtv-users mailing
list:

That's a frequent problem on Gentoo with a number of applications.

You should do opengl-update to set the default to xfree.  Then it will
compile.  Then change the default back to nvidia or whatever is
appropriate for your hardware.  Apparently nVidia wasn't smart enough to
make their include files compatible with the default.

I'll give this a try when I get home later on today.

I just tried to compile after the opengl-update xfree, and it compiled fine.

"opengl-update xfree" doens

"opengl-update xfree" doens´t help here. Tried it on 2 machines and now get
other compile errors.

Here's the error message:

the "opengl-update xfree" trick works for me, compiling with opengl and withOUT
directfb:

# emerge -pv mythtv
[ebuild   R   ] media-tv/mythtv-0.15.1  +alsa +arts -cle266 -directfb -dvb -lcd
-lirc -nvidia +opengl  0 kB 

Added a check for the curret OpenGL implementation to the ebuild. Thanks!
