Compilation fails on Raspberry Pi 5.15.32-v7+

[LukeLR]

Hi everyone,
I've successfully compiled the drivers for my TBS-5580 on Arch Linux, but I'm failing to do so on Raspbian for two days straight now. I've followed the instructions in the wiki:

git clone https://github.com/tbsdtv/media_build.git
git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media
cd media_build
make dir DIR=../media
make allyesconfig
make -j4
sudo make install

However, the make -j4 step fails with:

ERROR: modpost: "saa7146_pgtable_free" [/home/pi/git/media_build/v4l/saa7146_vv.ko] undefined!
ERROR: modpost: "saa7146_pgtable_alloc" [/home/pi/git/media_build/v4l/saa7146_vv.ko] undefined!
ERROR: modpost: "saa7146_pgtable_build_single" [/home/pi/git/media_build/v4l/saa7146_vv.ko] undefined!
ERROR: modpost: "__aeabi_ldivmod" [/home/pi/git/media_build/v4l/mn88436.ko] undefined!
ERROR: modpost: "__aeabi_uldivmod" [/home/pi/git/media_build/v4l/mn88436.ko] undefined!

What I've tried so far:

When commenting all occurences of saa7146_vv.ko and mn88436.ko in v4l/Makefile.media, build succeeds, but loading the module fails:

sudo insmod /lib/modules/5.15.32-v7+/updates/extra/media/usb/dvb-usb/dvb-usb-tbs5580.ko
insmod: ERROR: could not insert module /lib/modules/5.15.32-v7+/updates/extra/media/usb/dvb-usb/dvb-usb-tbs5580.ko: Unknown symbol in module

make menuconfig, as suggested in #220 fails with

/lib/modules/5.15.32-v7+/build/scripts/kconfig/mconf ./Kconfig
Kconfig.kern:502: syntax error
Kconfig.kern:501: unknown statement "option"

Any ideas on how to compile the drivers on Raspberry Pi?

Thanks a lot in advance!

Kconfig.kern:501: unknown statement "option"

You can remove the "option" statement at line 658 in the file make_kconfig.pl and run make menuconfig again.

Thanks, that helped. Now I get a terminal UI called "V4L/DVB menu" with a couple of selection options. Under Multimedia support -> Media device types I can select Digital TV, and Multimedia support -> Media drivers -> Media USB Adapters there is an option TurboSight TBS5580 CI support. Saving this file to the default name of .config and running make -j4 and sudo make install afterwards however installs just one module:

Installing kernel modules under /lib/modules/5.19.12-arch1-1/updates/extra/media/:
	pci/cx88/: cx8802.ko 

Even when enabling all possible options in all submenus, only this one module gets installed. So maybe the .config file needs to be saved under a different name?

[LukeLR]

Apparently, the .config file gets saved in the v4l subdirectory. However, it seems it's only read when saved to the main directory (media_build). When doing so, more kernel modules get build, but now I get

ERROR: modpost: "saa7146_pgtable_free" [/home/pi/git/media_build/v4l/saa7146_vv.ko] undefined!
ERROR: modpost: "saa7146_pgtable_alloc" [/home/pi/git/media_build/v4l/saa7146_vv.ko] undefined!

again. Any ideas?

[LukeLR]

I followed the instructions in #260 and the documentation linked by the user, and now compilation finishes with:

./scripts/rmmod.pl check
found 511 modules

Sounds reasonable, sudo make install also installs a lot of modules. However, loading the module still fails with:

pi@mediapi:~/git/media_build $ sudo modprobe -v dvb-usb-tbs5580
insmod /lib/modules/5.15.61-v7+/updates/extra/media/dvb-core/dvb-core.ko 
modprobe: ERROR: could not insert 'dvb_usb_tbs5580': Invalid argument

Any ideas? It can't be that hard to get this device running under Linux, what am I missing?
