mesa compile, talloc

[Trevor Woerner]

Hi,

I was trying to compile Xorg and had a bit of a stumble in the mesa directory.

The configure.ac looks for the talloc package and assumes your
distribution has supplied a "talloc.pc" to work with the pkg-config
system. Unfortunately mine doesn't so my build doesn't succeed.

Investigating this issue it appears as though the only parts of mesa
which need talloc are:
- src/mesa/program/ir_to_mesa.cpp
- src/mesa/main/shaderapi.c
- src/glsl

But what's even more interesting is that the talloc sources appear to
be included in the mesa package:
- src/talloc

If the talloc sources are being included in the mesa package, why does
the configure.ac require talloc be installed before you can start
building?

Can the 3 components which require talloc not use the talloc already
included in the mesa package?

Best regards,
    Trevor
