awesome, but it might be helpful if you told people how to enable it :D

this is how i did it.

Thanks mpan for showing the rest of us.

Hi Guys !

I can't enabled GlSl :(. I have ATI Radeon 9600 PRO (it supported OpenGL 2.0). Here is screenshot: http://img406.imageshack.us/my.php?image=blenderglslerrorwu5.png

Hi! I have Radeon 9600PRO and I have same problem as you. Thats strange, because this card have glsl support.

Miguel Torres Lima

You're right it must have glsl support or otherwise the button wouldn't even appear and it would use blender's drawing code. Sometimes the compiling errors are outputted in the text window, along with the shader code and many other things just for me to know what is happening rather painlessly, sometimes it is printed the compiling errors the driver outputs. I would be very grateful if you would send that part of the output in the text window to torreslima at gmail dot com.

Many thanks.

Miguel Torres Lima

Forgot to mention: I ask you for this because I don't have an ATI card.

Hi ALL,

I has the same problem of Jedrzej_s and jaha with my Ati X600. The issue occurs when I set a new material to a mesh.
Below the output of the console (in Windows XP):

GLSL Material created.

GLSL DefMaterial created.
Compiled with Python version 2.5.
'import site' failed; use -v for traceback
Checking for installed Python... No installed Python found.

Mine works (win XP, Nvidia) but setting a new material to a mesh crashes Blender everytime.

Hi, if I press the 'GLSL preview' button in the system and openGL section of the user prefs, it pops up a dialog titled "GLSL fragment shader compile error:", and the dialog contains one item with the label "GLSL support disabled", anyone know what the problem is?

ajuss

Hi,experiment with Jul-5-07 version.
i start with empty scene (no cameras, lights etc). Activate GLSL preview - it activates, then add sphere, then materila and when i add lights blender disables GLSL preview,
console: GLSL shader compile error
Memoryblock GLSL Node Code: end corrupt

I have ATI FreGL 3100 (latest drivers), P4 3,6ghz, 2gRam, WinXPsp2

JiriH

Works fine here with nVidia chip. Will there be also texture realtime prewiew enabled (something like texture shading mode combined with shading mode)? That would be really great, I suppose that Blender can handle this somehow as there is preview in texture buttons.

phexitol

Same error, ATI Radeon 9800.

Jens

Hi iguillaume
I will try to make an OSXintel Build, where do the f... glew-libs go ?
Have not found any advice up to now.
Greetz...Jens

Jens

Hi all. Got it. But on OSX it seem rather WIP. Some features work somehow, but
always "fragmentshader error ( relateted to svn 24.7.07 ). Have to keep an eye on progress. Greetz...Jens

James

I have a Nvidia geforce 6200 a-le, which supports Open GL 2.0 and I believe glsl. I don't see the glsl Preview in my list.

Hi all! Tried to compile the actual svn branch for myself, still end up with a linker prob when linking project blender (using cmake and vc++, see geneome.net). Could someone please give me a hint? Already fixed missing entries in some cmakelist.txt files but when it comes to linking it stops with unresolved symbols in src.lib function _glsl_shader_utils (the extern_glew.lib seems to be build correct). Thanks... nooblend

nooblend

Add: Nice to have your fantastic builds! Saw them, tried them, liked them very much and got the idea about compiling blender myself... and now you see what I've got ;-)!

RNS

I downloaded the file and open it it won't execute,because
a glew32.dll is not found? Help!

Wow, todays build(Aug-28-07) works with my ATI FireGL 3100 (WinXP, latest catalyst drivers for FireGL).

blendermf

it works on my ati radeon x1300 too, its awesome

Same problem as RNS : glew32.dll not found ( vista 32 / Radeon Xpress 1200 )

RNS

It seem that this built only work with High end Card.

Glew32.dll not found is not an error. Simply install glew32.dll into the blender directory! (google for the file)

Also, lguillaume, just wanted to let you know that the current build works flawlessly on *ATI* Radeon Xpress x1150 (notebook)

mpan3

...Xpress x1150, on WIndows XP with catalyst 7.8

RyanBarrett

I've just tried downloading this build from home and from work and I get CRC errors try to unzip in both places... so... there must be something wrong with the file.

Yeah, I know it has been asked. But Glew32.dll isn't found and i googled it. I found one, but Blender still ctashes. I have a Geforce 8600 GT
