I am having problems getting mythtv going!

I emerged qt with these options.

watson ~ # emerge -pv qt

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] x11-libs/qt-4.1.4  USE="cups gif jpeg mysql opengl png zlib -accessibility -debug -doc -examples -firebird -mng -nas -nis -odbc -postgres -sqlite -xinerama" 0 kB

Then I tried to emerge mythtv with like this..

w

Code: Select all

atson ~ # emerge -av mythtv

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] media-tv/mythtv-0.19_p10505  USE="alsa dvb dvd ieee1394 lirc mmx opengl vorbis xvmc (-altivec) -backendonly -dbox2 -debug -frontendonly -jack -joystick -lcd" VIDEO_CARDS="-i810 -nvidia -via" 0 kB

Total size of downloads: 0 kB

Would you like to merge these packages? [Yes/No] yes

 * MythTV requires Qt to be built with mysql and opengl use flags enabled.
 * Please re-emerge =x11-libs/qt-3, after having the use flags set.


 * You enabled the XvMC USE flag but did not configure VIDEO_CARDS with either
 * a Nvidia, i810, or VIA video card.

!!! Please fix the above issues, before continuing.
!!! If you need support, post the topmost build error, and the call stack if relevant.

I can not use VIDEO_CARDS="nvidia" because my KDE is blocking that option.

I am following this guide but I seem to be stuff that this point.

x11-libs/qt-4.1.4

* MythTV requires Qt to be built with mysql and opengl use flags enabled.
* Please re-emerge =x11-libs/qt-3, after having the use flags set.

Myth won't compile against qt4, you'll need to downgrade to qt3 to emerge it. I just quickpkg'd qt4, then put something like <=x11-libs/qt-4 into /etc/portage/package.keywords, then emerged myth again.

Once it's built, you should be able to comment out the qt4 line in /etc/portage/package.keywords and reinstall qt4 with emerge -k x11-libs/qt.

ok I am giving this a try thank you

well that got me past that now I just have the problem with the VIDEO_CARDS="nvidia" option since my kde blocks out the nvidia drivers.

Ok, sorry- I should have covered this in my last post, but I thought the XvMc portion was just a warning...

I'm also assuming that the build is now being blocked by: * You enabled the XvMC USE flag but did not configure VIDEO_CARDS with either a Nvidia, i810, or VIA video card.

If that's the case, you can avoid this by adding a line to /etc/portage/package.use:

Code: Select all

# Disable xvmc support to avoid specifying a specific video driver
media-tv/mythtv -xvmc

Of course, this disables XvMc support, but it's one or the other in this case. If your computer is powerful enough to run KDE, it shouldn't be needed anyway.

what can I do to see if my video capture card is detected? Also do I need to do anything in my kernel for this thing to work?

If you mean detected in the kernel, lspci is the command you're looking for. In myth, capture cards aren't automatically detected, you need to specify the card type and the /dev path to the correct card in mythtv-setup.

Kernel requirements vary with the type of capture card you have, but there are no additional kernel requirements added by myth. Once you have the capture card's drivers working in the kernel, you should be ready to configure myth.

As for getting the capture card setup, the myth docs and wiki are probably a good place to get a feel for what is required. They are updated more often than the Gentoo-specific howtos I've found, and they tend to be more accurate (IMHO).

Myth's docs on setting up a capture card:
