Description Alexandre Demers 2012-03-27 15:53:19 UTC 
When specifying --with-gallium-drivers=r600,swrast,svga, I'm able to compile correctly. However, when I specifying "export LIBDRM_LIBS=-L/usr/lib/x86_64-linux-gnu/" before building, the svga driver is unable to compile and results in the following error:

I tried removing manually "-L/usr/lib/x86_64-linux-gnu/", but the error was still happening.

However, if I remove svga from the gallium drivers list and recompile with the export still in place, I'm able to finish compiling correctly.
Comment 1 Alexandre Demers 2012-03-27 21:41:34 UTC 
By the way, you'll have understood by now that whatever you export into LIBDRM_LIBS breaks the build.
Comment 2 Michel Dänzer 2012-03-28 00:10:53 UTC 
As the name implies, LIBDRM_LIBS should contain any flags necessary for linking libdrm. According to the output of

 grep LIBDRM_LIBS *

in my Mesa tree, you need to add at least -ldrm to it.
Comment 3 Alexandre Demers 2012-03-28 11:48:13 UTC 
While I understand the possible need for -Ldrm, why would it be the only driver behaving like that? I mean, shouldn't the use of LIBS_LIBDRM=-L... replace the need for -Ldrm in a way, as it does for other drivers?

I'll be testing this solution later at home.
Comment 4 Alexandre Demers 2012-03-28 20:57:26 UTC 
Confirmed, I understood what you meant (have both -L... and -ldrm exported).
Thanks.
