Can't compile in nested directory

[sergey-suloev]

When I create a nested build directory and then invoke configure & make from it I always get compilation errors, like:

In file included from /home/sergey/Projects/orpaltech/mesa-anholt/src/broadcom/compiler/v3d_compiler.h:36:0,
from /home/sergey/Projects/orpaltech/mesa-anholt/src/broadcom/compiler/vir_live_variables.c:29:
/home/sergey/Projects/orpaltech/mesa-anholt/src/compiler/nir/nir.h:48:25: fatal error: nir_opcodes.h: No such file or directory
#include "nir_opcodes.h"
^
compilation terminated.

    v3d: Be more explicit about include directory from our generated code.
    
    You'd need src/broadcom/cle/ in the -I previously, for srcdir != builddir.
    nir was fine at that, but automake didn't have it.

Why close? It is not fixed by the change above.

[anholt]

Is it not? It passed on travis for me, with a srcdir != builddir test added.

src/broadcom/Makefile.am has "-I$(top_builddir)/src/compiler/nir ", which is where your built nir_opcodes.h should be. are you maybe trying to just build from a subdirectory of your builddir, instead of the whole thing?

[sergey-suloev]

Yes, I am creating a build directory inside mesa directory. This is a typical approach I have used for many libraries, and it all worked fine. This is how you can preserve initial source tree from modifications.

Oh, my bad, excuse me.
I did a full cleanup & rebuild again - it works!
Thanks.
