Issue Report: Shader generation/compilation fails in TF2 - temporary fix - proper fix WIP

[:owl:]

Workaround for now: export LC_NUMERIC=C before starting Steam.

Technical explaination:
The engine uses glibc functions to format the generated shader, and that breaks the output when the decimal separator for the locale used is not '.' (a dot), but ',' (a comma). Confirmed affected locales: ru_RU.UTF-8, fr_FR.UTF-8, likely more. Note the commas in the log (e.g. 1,164123 etc).

Log:

Compile of "?" Failed:
<snip>
vec4 pd0 = vec4( 1,.0, 0,.0, 1,.0, 1,.0 );
<snip>

Compile of "bik_ps20b" Failed:
<snip>
vec4 pd0 = vec4( 1,.0, 0,.0, 0,.0, 0,.0 );
vec4 pd1 = vec4( 1,164123535156.0, 1,595794677734.0, 0,.0, -0,870655059814.0 );
vec4 pd2 = vec4( 1,164123535156.0, -0,8134765625.0, -0,391448974609.0, 0,529705047607.0 );
vec4 pd3 = vec4( 1,164123535156.0, 0,.0, 2,017822265625.0, -1,08166885376.0 );
<snip>

A proper solution should be just to set the locale to POSIX before formatting the shader.

Got same when launched steam in console and run TF2.
Intel HD4000+Ubuntu 12.10 x86_64.

Confirmed on Ubuntu 12.04 amd64
GeForce GTX 480

It seem by the comments, all (or many) ubuntu 12.04 for amd64 are affected. 12.10 for amd 64 is fine.

[:owl:]

It's weird how 12.04 is affected, 12.10 is not, and Arch current (which is what I'm running) is affected. That means something was introduced in 12.10 that is used by the engine, but is actually an Ubuntu quirk/feature.

I haven’t seen this on Ubuntu 12.04 amd64 GeForce GT 630

What driver version/graphics chip are you running guys? We should make a list of affected setups so it's easier to identify the problem.

Thanks for the info everyone. Please keep reporting the problem configurations.

I had same issue but Valve didn`t pay attention to it.

Solution:
1) open console 2) type "export LANG=C" 3) type "steam" 4) TF2 working just great after this step (when locale becomes "C").

Seems like 12.04-only issue.

You mean

$export LANG=C steam

It doesnt work for me, Steam does not launch.

It isnt. I tried it on 12.10 and openSUSE 12.2.

[SUSEd]

BTW, provide some logs after you launched TF2.

[northernNed]

I am having a similar issue. When TF2 launches all I have is a black screen and cursor, I also hear the Valve intro sound but I don't have any image. I am able to bring up the overlay by using shift+tab

@shished
1) Run "export LANG=C"
2) Run "steam"
