Driver ABI update?

[KaiJan57]

A recent xorg-server update on arch linux generated conflicts with xf86-video-opentegra-git from AUR, so I updated the package conflict X-ABI-VIDEODRV_VERSION. This driver installs fine now, but it seems to be missing symbols, preventing xorg from loading it. The error message for xorg server version 1.21.1.3 reads: Failed to load /usr/lib/xorg/modules/drivers/opentegra_drv.so: /usr/lib/xorg/modules/drivers/opentegra_drv.so: undefined symbol: exaDriverFini Maybe implementing exaDriverFini is enough to get the driver running again?

You should need to rebuild the xf86-video-opentegra package after Xorg's upgrade, have you done it?

[KaiJan57]

Sure, compiles fine, but xorg gives said error...

I don't see that problem using Arch and Xorg 1.21.1.3, but I don't use xf86-video-opentegra-git and compiling/installing opentegra manually. Either you're somehow installing the older package build or there is a problem in the pkgbuild script, maybe a missing dependency?

Please check whether you have these lines in the Xorg's log, you should've the compiled for 1.21.1.1:

(II) Loading /usr/lib/xorg/modules/drivers/opentegra_drv.so
(II) Module opentegra: vendor="X.Org Foundation"
        compiled for 1.21.1.1, module version = 0.6.0

EDIT: one package that failed to upgrade seems to have blocked a lot of xorg infrastructure from upgrading. I fixed dependency issues and am looking forward to have opentegra working again after updating said xorg packages.

Odd, it doesn't even show the expected line… context:

Also, I checked the build directory to make sure it indeed checks out the current version of the master branch.

No still undefined symbols, even when installing with make install :(

I retried manual make install using latest Arch Linux and it works using this method:

git clone https://github.com/grate-driver/xf86-video-opentegra.git
cd xf86-video-opentegra
sh autogen.sh --prefix=/usr
make install

I tried to build/install the PKGBUILD and I'm getting the same error as you.

I applied compiler flags changes to the PKGBUILD, which I picked up from https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=xf86-video-intel-git, and now it works:

Thank you so much for your time even fixing the PKGBUILD! It works now, after also cleaning the package's build directory.

[digetx]

You're welcome. Is it possible to update the AUR's PKGBUILD?

[KaiJan57]

AFAIK the maintainer has to change it. But it is possible for everyone to pit patches into the comment section, so others are aware of this fix.
