gentoo with 270.30 - broken /usr/bin/nvidia-smi (requires libnvidia-ml.so.1)

[ThunderRd]

On my 64-bit Gentoo install the driver seems to install and function correctly with xorg-server-1.10, but Gentoo reports a reverse dependency problem as stated in the title:

Q6600 ~ # revdep-rebuild -ip

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   #] x11-drivers/nvidia-drivers-270.30

After allowing the system to rebuild the driver (which happens successfully) revdep-rebuild reports the same, as if nothing has been solved.

nvidia-smi does exist in /usr/bin, but libnvidia-ml* does not exist anywhere:

Q6600 ~ # ls -al /usr/lib/libnvidia-ml.so.1

the ebuild is broken then ?

that lib is in the official driver: http://www.nvnews.net/vbulletin/show....php?p=2404906

also attaching the bug-report is useless here since your system does not contain the nvidia install build log:

*** /var/log/nvidia-installer.log does not exist

:-\

[ThunderRd]

Hmm...you're right about that log file. I wonder why it wasn't produced?

Unfortunately, xorg updated but gentoo does not have the 270.30 driver in portage as yet. I got the driver out of the stuff overlay, and it does seem to work properly, although it's reporting that unsatisfied dependency. What exactly is that library responsible for, and will I miss it until the 270.30 is in the tree?

AFAICT I won't miss it, but I'm not 100% sure yet.

ebuild is attached below, if you are interested.

[ThunderRd]

I seem to have solved the error by downloading an Arch tarball and extracting the missing libraries and symlinks to /usr/lib32 and /usr/lib64. Everything seems to work and revdep-rebuild is happy now.

Thanks for pointing me in the right direction.

[Txema]

I don't know what ebuild you are using but i renamed the ebuild of 270.26 version to 270.30 and all worked perfectly, even that file you said was missing is present in my installation

That's probably a Gentoo packaging bug.

libnvidia-ml is the NVIDIA Management Library. The cross-platform NVML API provides functions for querying and configuring the GPU. nvidia-smi, which was formerly a standalone app, is now an NVML client.

Since the libnvidia-ml DSO is new in the 270.xx drivers, it seems likely that some distro maintainers might have missed it when repackaging the driver.

[ThunderRd]

Thanks for that information, danix. I'll see if I can confirm that with people in the know from the Gentoo side.

270.30 is not yet in portage.

I have no problems with /usr/lib/libnvidia-ml.so.1 file and older (official) ebuild copied to 270.30.

[ThunderRd]

It must be a problem with the ebuild in the stuff overlay. Just to test it I might do as you say and copy over the 270.18 to 270.30 and see if it installs correctly.

He'll also need to change the xorg-server dependency from <x11-base/xorg-server-1.10.0 to <x11-base/xorg-server-1.10.99 when copying that ebuild, otherwise it will block xorg-server-1.10.0.
