Operating system: Windows 7 - 64-Bit Edition on Compaq Presario CQ62 (4Gb RAM)

Graphics card: ATI Mobility Radeon HD 4250
Latest driver installed: Catalyst Software Suite - Revision Number 13.9
with 13-9-legacy_vista_win7_64_dd_ccc_whql.exe from ATI

Broken: Blender 2.80

Problem: the win64 daily build crashes on start (see console output hereafter)

This problem appeared recently (about 1 week ago).
I have an "old" blender-2.80-0f5b53ba4dc-win64.zip built (01 Dec 2018) which is OK, tested today on same config, with only some warnings:
Win32 Error# (8341): The specified OpenGL version and feature set are either inv
alid or not supported.

Thanks
Pierre

Your GPU has been EOL from a while now. The latest driver release is from 2013.

@fclem I think this is sadly too outdated to support.

Can you run with the --debug option and paste the output into a text file and upload it here?

I can understand the new 2.80 can require a GPU not so outdated, but I was just surprised to have it working on 1st Dec 2018 and then crashing with recent builds. May be something has changed, and the problem is perhaps not linked to my old GPU ...

Same problem with latest build blender-2.80-16fc62e15f0-win64.zip
Here is the output with --debug: blender-2.80-16fc62e15f0-win64.debug

I don't know if it can help, but I found this closed task #59043.
https://developer.blender.org/T59043
This was the same problem on a ATI Radeon HD 3450.
The task was closed when the problem disappeared in blender-2.80-cfa1700-win64-vc14.

I have the same errors with latest build:

Thanks a lot for fixing!

I suppose the Fix is not included yet, because I still have the same crash with the daily build (yesterday and today)

Is there somewhere a list of fixes included in each daily build ?
Or how can we know when a Fix will be included in the daily build ?

If the daily build is from the Dec 15, it should be in. If it is still not working please give the --debug-gpu log of the new version.

May be a problem with default precision declarations ?

page 63:

The fragment language has the following predeclared globally scoped default precision statements:

precision mediump int;
precision lowp sampler2D;
precision lowp samplerCube;

The fragment language has no default precision qualifier for floating point types. Hence for float, floating point vector and matrix variable declarations, either the declaration must include a precision qualifier or the default float precision must have been previously declared.

Well the issue is that precision qualifier is only for opengl ES and we don't support it.

I commited 30a0f1a2bf to try to fix this issue.

Thanks for the Fix.
Waiting for next build to have a try.

About the damned "mediump int", this seems to apply to standard (non-ES) OpenGL 3.3 too:

https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.3.30.pdf
in 4.5.3 page 44:

The fragment language has the following predeclared globally scoped default precision statements:

Good news!

Your Fix "<< int(ROUGHNESS_BITS);" works.
No more compilation errors on Fragment shader.
