[PATCH] Fix out-of-tree builds with intel-gen4asm installed (1.12 KB, patch)

Description Josh Triplett 2012-10-05 00:12:50 UTC
With gen4asm installed, out-of-tree builds fail with errors like this:

m4: cannot open `field_backward.g4a': No such file or directory

Looks like the make rules for gen4asm files reference the source files via their basenames without using srcdir, which only works for in-tree builds.

This breaks when trying to build the current Intel driver on ChromeOS, which uses out-of-tree builds for everything.

    Fix out-of-tree builds with intel-gen4asm installed
    The make rules to compile shaders with intel-gen4asm referenced the .g4a
    source files without using $(srcdir), which broke out-of-tree builds.
    Reference .g4a source files via $(srcdir), and add $(srcdir) to m4's
    include path, fixing out-of-tree builds.
