           Summary: Second Life crashes on starting ( Linux 32-bit )
           Product: Mesa
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: andabata12 at yahoo.it


The crash came  with this declaration

ir_dereference_variable @ 0x138248b0 specifies undeclared variable
`gl_LightModel' @ 0x133d8148


I had this problem  from Mesa Git  request of talloc to compile  and from
commit of " glsl: add missing ambient field to gl_LightModel" by Luca Barbieri.
In practice from ca 20-25 August 2010 i have to compile from mesa git  and
subsequently to substitute r300g_dri.so  with a 8/16/2010 radeong_dri.so
luckily saved from an old compilation; 

thus  i have finally the whole bunch of graphic settings on SL with a Ati X1700
(rv530).

In this last period  i have not crashes for gl_light ( i noticed the correction
in commit mesa: Clean up header file inclusion in light.h.) but if i try to use
the compiled r300_dri.so i get crash with:

2010-12-08T19:39:56Z INFO: loadShaderFile: Loading file:
shaders/class2/environment/terrainF.glsl (Want class 2)

do-not-directly-run-secondlife-bin: ir.h:851:
ir_call::ir_call(ir_function_signature*, exec_list*): Assertion
`callee->return_type != __null' failed.
inworld.

The same happens  with stock Mesa for Fedora 13 and 14 and with different
releases of SL viewer.

If i don't  set "basic shaders" in Second Life viewer configuration, i can log
inworld.

So I  came back to kernel 2.6.35.9-64.fc14.i686 and with last X server and ati 
driver, last libdrm from kojii and transplanted old radeong_dri.so in
/usr/local/lib/dri i have a relatively good experience on Sl, but the same it
is a pity because i feel that Mesa-Gallium could compete  with proprietary
drivers on Second Life.
