Bad Useflags…

Filed under: configuration — Tags: , , , — niko86 @ 22:22

Everything finished compiling.
I just emerged xmltv and some grabbers.

After that i noticed a real bad mistake..
i had the Use flag “-X” in my make.conf.
mythtv-setup requires an X Server, this is clearly stated in the mythtv documentation…
That’s why you should always read the docs…

So im off to emerging all the X stuff.
Currently im setting up a vnc server because my backend is headless…

more trouble

compiling stopped again with this message:

* 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 can't have USE=autostart while having USE=backendonly.
* USE=autostart is for mythfrontend

so apparently i have to enable mysql and opengl use flags for Qt and remove the autostart useflag for mythtv.

let’s see…

hell of a job

As posted i started compiling after assembling the backend.

i did not remember it correctly, it actually is a P4 2.8 ghz which is now working in the backend.

so let’s get to the point, since i now got two older Hard Drives i thought i should do a Raid Array with Raid Level 0.

So just did it and started building the Kernel.

Everything worked fine, Raid Performance measured with hdparm:


Timing cached reads:   1888 MB in  2.00 seconds = 944.21 MB/sec
Timing buffered disk reads:  218 MB in  3.00 seconds =  72.58 MB/sec

I think that’s not bad for some old dusty Harddisks.

Crawling through the Kernel Options for Multimedia Functions was a bit painful since there are lots and lots of different settings.

Mainly i enabled some Phillips Drivers, bt848, PVR, ivtv.

Seemed to work fine.

Rebooted into the system, added some USE-Flags:


USE="-X -ipv6 -alsa -xscreensaver apache2 mysql pam php curl curlwrappers cgi gd jpeg png gif \
xml cdr dvd lm_sensors quotas syslog fam suexec bash-completion sqlite pdo simplexml sockets posix"

I read some bad things about that “backendonly” Use Flag of mythtv, but I’ll give it a shot.
mplayer and ffmpeg are there for some transcoding, i don’t know if i will actually need it.

started upgrading it and building mythtv…

what a hell of a job.
some of the ebuilds are already broken.
the pvr_firmware driver for example, they changed the url for some archive, so you have to manually download the archive and remerge it again. (

The current Status:

I’m currently recompiling the Kernel since the building suddenly stopped with this Error:


*   CONFIG_VIDEO_HELPER_CHIPS_AUTO:     should not be set. But it is.

So i disabled this option, recompiled and remerged.
