[OpenRC / MediaTek / Kernel 6.0+] VCOM Driver compiling error.

Heyo,

I was trying to compile a VCOM Driver for unbricking a MediaTek phone, but unfortunetly it crashed. I was using yay to build the package and that's the log:

Is there some way to install that driver on Artix with OpenRC init system & kernel 6.0+?

Re: [OpenRC / MediaTek / Kernel 6.0+] VCOM Driver compiling error.

Somewhere (PKGBUILD or Makefile) there's this compiler directive: "-Werror=implicit-function-declaration" (treat warnings as errors and abort). Perhaps there's a broader "-Werror" too. Disable and retry.

Re: [OpenRC / MediaTek / Kernel 6.0+] VCOM Driver compiling error.

I looked for that through `grep`, but finds nothing.
Code: [Select]
grep -r Werror *

I also tried adding `-Wno-error`, but didn't worked. Error is still the same.

That's a very complicated PKGBUILD.

I think the driver's quite tied to kernel versions. There is a more recent version of the driver which you tried to compile manually but at a guess the existent PKGBUILD would need a major rewrite to build to the 2.3.0 version.

If it was me trying to resurrect dead hardware I'd by tempted to try the following:

Email the maintainer (obfuscated address in the PKGBUILD) and politely ask if they could update to 2.3.0
Leave a similar message on the AUR page.
Bear in mind that systemd is mentioned repeatedly in the PKGBUILD, more than just a service file,  so even if it builds it may still not work.

The instructions
https://advdownload.advantech.com/productfile/Downloadfile1/1-26F2D41/VCOM2.0%20Driver%20for%20Linux%20Installation%20Guide_v1.4.pdf
seem outdated, 2.2.1, but list compatible distros with that version.
I'd be tempted to install the most recent one listed you have experience with (eg Ubuntu 18) in a VM (Or maybe better a spare partition, unless you have bleeding edge hardware it should still work)
Then follow the instructions to compile and (if using the VM) connect the phone with USB passthrough to the VM.

I think the 2.3.0 version is failing to compile due to multiple definitions of the same variable. Older versions of gcc apparently tolerated this but newer versions do not. It maybe fixable with flags but I'm not sure?

Even after looking at the instructions I'm not sure what this does ? So take any of my advice with a pinch of salt.
It's just food for thought.

I tried to contact the maintainer of the AUR months ago, but no response.

There are some options to emulate systemd on OpenRC, but the driver fails at the beginning.

I'll try to run a VM, but the goal is to install the driver on the real machine.

I tried using some flags, but still fails to build.

What that does is basically modyfing detection of the MediaTek device after entering the state before bootloader. It's using USB controller and without it the MediaTek device is appering on 1 sec, later on dissapearing for a while and then again appearing.

I thought the goal was just to unbrick a phone?
But regardless if you have a spare partition, or even a reasonably sized USB3 key, it may well be possible to dual boot it on bare metal.

What I didn't consider before is availability of repo's. But it seems Ubuntu18.04 is a LTS release so the repo's should still be up I think?

I imagine to get it going on Artix an older kernel  + headers, from the relevant era, and also gcc from that era might help.
Even just a slightly older gcc might help with the 2.3.0 version ? But Id sooner not try those downgrades on my daily driver.

Personally I'd try the VM.

The goal of the topic is to compile & install the driver.
Later on I'll unbrick phone with Stock ROM. ツ

Fair enough but I still suspect that you either need kernel headers + gcc from around the time the drivers were published or the ability to fix the problems in the code. I don't have the latter. It may, and hopefully will, be trivial.

One other possibility if you want to keep it within Artix is do it in a chroot.
I wish you luck.

Actually I totally lost a bricked device after reading that when it's hard bricked, it requires special device to recover + resoldering data chip.

So I can't do any tests with VCOM / SP Flash Tool. Guess, I'll close the topic..

Also VCOM Driver seems to don't have any support from the Advantech.
