Hi, After analyze how build Mesa from CVS with "make linux-x86-dri" and how xorg built same Mesa source with "make World".
Ian Romanick has point that Mesa code should have IN_DRI_DRIVER Define.
So, I found on xc/lib/GL/mesa all subdirs: shader swrast tnl x86 main
math and tnl_dd have missing at least -DIN_DRI_DRIVER
Xorg build also misses -DPTHREADS -DUSE_EXTERNAL_DXTN_LIB=1 -DHAVE_ALIAS
Ian, and those ones are needed ?
As side note I haven't the minimum idea, what side effect this could
cause on non Linux or BSD systems.
