While the generated format_*pack.c files work when build is done in the source directory, things break when build is done in a separate directory (which has worked fine until now). $ make make[4]: Entering directory '<path>/mesa/64bit/src/mesa' CCLD libmesa_sse41.la make[4]: *** No rule to make target '../../../src/mesa/main/format_pack.c', needed by 'format_pack.lo'. Stop. $ find .. -name format_pack.c ../64bit/src/mesa/main/format_pack.c Makefile refers to generated files from source directory although it should refer to them from build directory.
Thanks for reporting the bug. Have you rerun autogen.sh in the separate directory? It will regenerate the Makefile.in files. This is happening because format_pack.c and format_unpack.c were tracked by git before but now they are autogenerated, so the Makefiles need to be updated. More info in this email [0] and the previous replies in the same thread.

> Have you rerun autogen.sh in the separate directory? It will regenerate the Makefile.in files. Yes, I had run it (and "make clean"). Re-running them didn't help either. However, everything works with clean checkout. -> INVALID & Sorry for the noise. (It seems that my checkout and/or build directory had stale files that don't get re-generated by autogen.sh and/or aren't (anymore) in git, but which still manage to break the build. I remember something similar happening with the driver transition.)
