Bug 4706

Same problem.

I fixed by rebuilding libtxc_dxtn for i686 and x86_64. I was then able to install Steam.

in steam.spec we have [1] but mesa now have libtxc_dxtn ,  Simone Caronni may we drop this requirement ?

Yep, it is fixed. Thank You very much!

I am getting a very weird behavior with this issue:

Searching for this package:

dnf search libtxc_dxtn
Last metadata expiration check: 1:50:33 ago on qua 15 nov 2017 16:03:03 -02.
================================================================================= Name Exactly Matched: libtxc_dxtn =================================================================================
libtxc_dxtn.i686 : Free implementation of the s3tc texture compression algorithm
libtxc_dxtn.x86_64 : Free implementation of the s3tc texture compression algorithm

So, I get a match, the package seems all right.

But then,

sudo dnf install libtxc_dxtn
Last metadata expiration check: 0:00:25 ago on qua 15 nov 2017 17:53:18 -02.
No match for argument: libtxc_dxtn
Error: Unable to find a match

Weirder still,

dnf info with the package's name works. What can I do to fix this issue?

Good point, I forgot that the patent was about to expire. We can drop the dependency where Mesa it is already at a version that contains S3TXC support, which seems to be 17.3.0:

https://cgit.freedesktop.org/mesa/mesa/commit/?id=d400348c73f0901eb24ff4d1562043d3119ef439

So far, only in rawhide. I will prepare an update.

Thanks for remembering this!

Hi !, 

Ajax had already backport it for Fedora packages, he wrote that in Fedora-legal mailing list  [1], my question is that I don't find any libtxc_ in new mesa packages ...

Sorry, missed Adam's changelog in Mesa. Rebuilding.
Build without dependency is steam-1.0.0.54-13.

It has been merged in other files:

I mean in pratical way .
1 - I may have mesa and libtxc_dxtn-1.0.1-2.gitef072983.fc26.i686 installed without conflict because /usr/lib/libtxc_dxtn.so only exist in libtxc_dxtn 
2 - None of the 20 packages of mesa got the same libtxc.so, if mesa already have libtxc, I don't see where , neither I know how I test the existence and good working of libtxc .
