Compilation of CrazyCat's media_build

schnere · July 8, 2019 at 8:04 PM

Hi,

I have a TechnoTrend TT-4600 DVB-S2 USB box and figured out that it only works with CrazyCat's Firmware/Drivers.

I use LibreElec as client but want to use Manjaro ARM as server. For this reason I've tried to compile CrazyCat's media_build .

Unfortunately it always completes with errors.

Here is the full log of the process:

Some details of my System:

Manjar ARM

Release: 19.06

Kernel:

Linux vdr01 5.1.16-1-MANJARO-ARM #1 SMP Fri Jul 5 07:42:44 UTC 2019 aarch64 GNU/Linux

Code

I'd hope that someone could give me a hint on this.

EDIT: might have something to do with this?

Thanks for your reply. As you can see in the log, that's exactly what I did.

But the compilation fails.

What about

Code

cd media_build
make download
make untar
make -C v4l allyesconfig
sed -e 's/CONFIG_TEGRA_VDE=m/# CONFIG_TEGRA_VDE is not set/g' -i v4l/.config
make

schnere · July 10, 2019 at 9:37 AM

Mhm, make after changing the CONFIG_TEGRA_VDE value did not work:

After 'make distclean' I'm now compiling as you suggested in your last post.
Thanks for your help, I really appreciate it!

EDIT: in you sed command, sed CONFIG_TEGRA_VDE=m should get replaced with # CONFIG_TEGRA_VDE is not set .

Assumed it the other way, because # CONFIG_TEGRA_VDE is not set is the default value. Changed it now and it's again compiling...

**vpeter** · July 10, 2019 at 10:03 AM

Try

Code

sed -e 's/CONFIG_VIDEO_CODA=m/# CONFIG_VIDEO_CODA is not set/g' -i v4l/.config

And it is not the same error

If is not set is default value then you don't need to use sed on that one.

schnere · July 10, 2019 at 12:16 PM

Omg, I was stuck on researching for tegra_vde so that I didn't think about disalbing coda .

Got another error:

Code

make[3]: *** Keine Regel vorhanden, um das Ziel „/home/vdr/media_build/v4l/vdec/vdec_h264_if.o“, 
  benötigt von „/home/vdr/media_build/v4l/mtk-vcodec-dec.o“, zu erstellen.  Schluss.

So, disabled that, too:

Code

sed -e 's/CONFIG_VIDEO_MEDIATEK_VCODEC=m/# CONFIG_VIDEO_MEDIATEK_VCODEC is not set/g' -i v4l/.config

After that compilation went through. So I did a "make install" and rebootet, but now by DVB-S2 box is not getting detected:

Code

dvb_usb: Unknown symbol dvb_create_media_graph (err -2)

I assume this could be caused by using distcc for compilation ?

Code

DISTCC_HOSTS="192.168.0.11:3636,lzo,cpp" pump make -j5 CC="distcc aarch64-unknown-linux-gnu-gcc"

So, compiling again - without distcc - will take some time now

Code

cd media_build
make distclean
make download
make untar
make -C v4l allyesconfig
sed -e 's/CONFIG_VIDEO_CODA=m/# CONFIG_VIDEO_CODA is not set/g' -i v4l/.config
sed -e 's/CONFIG_VIDEO_MEDIATEK_VCODEC=m/# CONFIG_VIDEO_MEDIATEK_VCODEC is not set/g' -i v4l/.config

Mhm, still no luck

Code

**vpeter** · July 10, 2019 at 3:52 PM

Check if you have CONFIG_MEDIA_CONTROLLER_DVB in .config file.

schnere · July 10, 2019 at 4:19 PM

Yes:

Code

$ grep CONFIG_MEDIA_CONTROLLER_DVB v4l/.config 
CONFIG_MEDIA_CONTROLLER_DVB=y

Maybe you need to load another module before dvb-usb.ko? Like dvb-core.ko.

schnere · July 10, 2019 at 5:43 PM

If I use upstream linux-tv git repository instead of CrazyCat's I get a different error:

Code

[   68.705948] mc: exports duplicate symbol __media_device_register (owned by kernel)

I've tried modprobe m88ds3103 dvb_core i2c_mux before, but that didn't work either.

**vpeter** · July 10, 2019 at 5:47 PM

Then I'm out of ideas. Grep your media_build folder for missing symbol and why it is not included.

schnere · July 12, 2019 at 9:25 PM

Okay, dvb_create_media_graph is defined in dev-core: Linux source code: drivers/media/dvb-core/dvbdev.c (v5.2) - Bootlin

lsmod | grep dvb has no output, so dvb-core is not loaded which must cause the problem with dvb-usb.

But when I do modprobe dvb-core I get no output, but it still isn't loaded.

Code

$ modprobe --show-depends dvb-usb

As i can see dvb-core depends on media which is also not loaded.

**vpeter** · July 13, 2019 at 8:05 AM

I think you are mixing modules from a system and modules from media_build. Maybe you are using dvb-core from a system but you should from media_build (it needs higher priority) - that's why you are missing symbols.

As I remember modules from media_build should be put in some special folder under /lib/.
