Lightbulb 32-bit compat libtxc_dxtn package is needed for Team Fortress 2 with radeon driver


This is just a post about something I figured out. Running 64-bit Slackware 14.2 with the open-source radeon driver, I found I had to create a compat32 package of libtxc_dxtn from SBo in order to get Team Fortress 2 to work.

The original error message Team Fortress 2 (TF2) gave me was "This application requires either the GL_EXT_texture_compression_s3tc, or the GL_EXT_texture_compression_dxt1 + GL_ANGLE_texture_compression_dxt3 + GL_ANGLE_texture_compression_dxt5 OpenGL extensions. Please install S3TC texture support."

For more background info, my glxinfo | grep OpenGL is:
Code:
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD BONAIRE (DRM 2.43.0, LLVM 3.8.0)
OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.2.2
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 11.2.2
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:
I originally only had a 64-bit version of libtxc_dxtn installed.

Glad you figured that out. libtxc_dxtn is a frequently needed application for games (at least Source-based games on Steam). And if that game is 32bit, you'd need the 32bit version of it as well. Hopefully this post will help others who may come across that error and find this post through a web search.

bassmadrigal - thanks, yeah, that's what I was hoping! I also discovered that installing this 32-bit libtxc_dxtn is necessary for the textures to load properly in Civilization V. Before I had this library installed, Civ V would start up and run, just without any textures which, of course, made the game very difficult to play.

I apologise for resurrecting an old thread, but how do I create a compat32 package for libtxc_dxtn? I'm on Slackware64 14.2 and have the x86_64 version installed from SBo, and have AlienBob's multilib system up and functioning.

You can compile 32bit executables on your 64bit system by following the instructions in this page
https://wiki.alienbase.nl/doku.php?i...2-bit_programs

In alternative, grab a precompiled 32bit package from some repository (alienbob,ponce,rworkman,slacky,slackonly) and use the utility convertpkg-compat32 to generate a compatible multilib package (detailed instructions on the procedure in the link above)
