Compile with Ubuntu 26.04 failing

[Jimsoft1]

Getting this error compiling ...

creating symbolic links...
make[2]: Entering directory '/usr/src/tbs/media_build/v4l/firmware'
make[2]: Nothing to be done for 'default'.
make[2]: Leaving directory '/usr/src/tbs/media_build/v4l/firmware'
ln: will not overwrite just-created './venc.c' with '../linux/drivers/media/platform/amphion/venc.c'
ln: will not overwrite just-created './vdec.c' with '../linux/drivers/media/platform/amphion/vdec.c'
make[1]: *** [Makefile:264: links] Error 123
make[1]: *** Waiting for unfinished jobs....
make[1]: Leaving directory '/usr/src/tbs/media_build/v4l'
make: *** [Makefile:26: all] Error 2

Looks like it fails at line 263 in ./media_build/v4l/Makefile which is ...

@find ../linux/drivers/media -name '*.[ch]' -type f -print0 | xargs -0n 255 ln -sf --target-directory=.

Any help would be useful.

Thanks, Graham.

hi,
try this command line to install tbs card driver .
curl -sSf https://www.tbsdtv.com/download/document/linux/drv-tbs.sh | sh

best regards!

Hi,

Well I tried this and as I suspected it stopped the devices I did have from working. I have 3 devices, 1x TBS6981, 1x TBS6281 and 1x Astrometa DVB-T2 in my system. The TBS6981 and the Astrometa were working but after trying the above I now have no tuners at all, nothing in /DEV/DVB.

Graham.

[zhang111chao]

tbs6981 and tbs6281 is very old card , you need to install from github .

please refer to this link ; https://github.com/tbsdtv/linux_media/wiki
support kernel version from v4.19-6.14

[zhang111chao]

i suggest to install ubuntu 2004 . tbs6981 and tbs6281 is the very old card .

[home-debug]

I made a script by Claude Code AI for Debian and kernel 7.0. it's working for saa716x and tbsec3 models.
Just try use it and modify for your configuration, maybe someone will make it universal for all distros

I recently ran into something similar, however you don't need to remake the Makefile to select individual drivers. You do need to restore previous IS_REACHABLE checks however:

Then simply ensure that the module is known to kbuild and redfine MODDEFS to the same. This is an example from a Gentoo ebuild:

src_prepare() {
	default

	# why is all here??
	sed -i 's/install: all/install:/' Makefile || die
}

src_compile() {
	local mods=(DVB_CORE DVB_TBSECP3 DVB_CXD2878)
	local moddefs=$(printf " CONFIG_%s=m" "${mods[@]}")
	export EXTRA_CFLAGS+=$(printf " -DCONFIG_%s_MODULE=1" "${mods[@]}")

	emake kernelver="${KV_FULL}" MODDEFS="${moddefs}" all
}

src_install() {
	emake kernelver="${KV_FULL}" MDIR="${ED}" install
	modules_post_process
}

I'm not a coder, I'm using ai, and it just works with kernel 7.x without compile whole kernel tree, but only the TBS drivers, without gpu and sound problems, it's first version working, not final :)

@JohnFlowerful your method is looking like works only in Gentoo way

@home-debug,
Would you be kind enough to elaborate on what you've done and how to do it?
Thanks.

I have 2 cards tbs 6922 I tbs 6902, cause official drivers looks like abandoned, I use Claude AI to make script without modyfiy sources compile only TBS drivers, not whole media kernel tree. Read readme how to use it. https://github.com/home-debug/TBSonly.
If something will not working for you use Claude AI to fix, but it should be work on all Debian based distros
