Description Fabio Pedretti 2012-06-02 00:20:14 UTC 
Since recent mesa git changes I am getting this compile error:
  CC     api_arrayelt.lo
../../../../../src/mesa/libdricore/../main/api_arrayelt.c:45:27: fatal error: main/dispatch.h: No such file or directory
compilation terminated.

Comment 1 Tapani Pälli 2012-06-04 06:10:27 UTC 
It seems dependencies for parallel build in makefiles may not be set correctly, one can see that dispatch.h gets generated only a bit after build of libdricore needing it fails.
Comment 2 Fabio Pedretti 2012-06-05 07:21:43 UTC 
I tried doing a non parallel build but I get the same error:

Comment 3 Darren Salt 2012-06-14 12:00:36 UTC 
The problem looks like include path brokenness. Generated source is put in the build tree, but it's looked for in the source tree.

I managed to get a build done by copying the following from build to source:

src/glsl/builtin_function.cpp
src/mapi/glapi/glapitable.h
src/mesa/main/api_exec_es1_dispatc.h
src/mesa/main/api_exec_es1_dispatch.h
src/mesa/main/api_exec_es1_remap_helper.h
src/mesa/main/api_exec_es2_dispatch.h
src/mesa/main/api_exec_es2_remap_helper.h
src/mesa/main/dispatch.h
src/mesa/main/enums.c
src/mesa/main/remap_helper.h
src/mesa/x86-64/matypes.h
src/mesa/x86/matypes.h

Correct; this is an out-of-tree build issue.

Sadly, the naive solution of changing those references to be relative to $(top_builddir) rather than $(srcdir) runs into problems in src/mesa/Makefile; possibly the best way to fix this is to continue the automakification to src/mesa.

Is having both a problem? Or just using $(builddir) [not top]?

I don't think this is still relevant. Please reopen if it is.
