The problem I see is that these files are built, but don't get any useful contents as I failed to convert setting the preprocessor flags correctly. Please try the attached patch.

Separate then out the way they were before, putting pre-processor flags into AM_CPPFLAGS, so assembly source gets preprocessed with the correct pre-processor flags as well. Also, remove unneeded CFLAGS from AM_CFLAGS, and CXXFLAGS from AM_CXXFLAGS --- src/mesa/Makefile.am | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/src/mesa/Makefile.am b/src/mesa/Makefile.am index a454a32..584458b 100644 --- a/src/mesa/Makefile.am +++ b/src/mesa/Makefile.am @@ -102,8 +102,9 @@ noinst_LTLIBRARIES = libmesa.la libmesagallium.la SRCDIR = $(top_srcdir)/src/mesa include sources.mak -AM_CFLAGS = $(API_DEFINES) $(DEFINES) $(INCLUDE_DIRS) $(LLVM_CFLAGS) $(CFLAGS) -AM_CXXFLAGS = $(API_DEFINES) $(DEFINES) $(INCLUDE_DIRS) $(LLVM_CFLAGS) $(CXXFLAGS) +AM_CPPFLAGS = $(API_DEFINES) $(DEFINES) $(INCLUDE_DIRS) +AM_CFLAGS = $(LLVM_CFLAGS) +AM_CXXFLAGS = $(LLVM_CFLAGS) # cannot just add $(MESA_ASM_FILES) to libmesa_la_SOURCES as it contains a configure substitution MESA_ASM_FILES_FOR_ARCH = -- 1.7.9
