Hmm, I only build sparse-llvm on cygwin these days (I don't have
llvm installed on Linux at the moment). You didn't say which system
and versions of OS, compiler and llvm you are using.
However, I think it may be more appropriate to add:
$(shell $(LLVM_CONFIG) --cppflags)
rather than these specific '-D'efines.
On cygwin, for example, I see:
$ llvm-config --cppflags
-I/usr/include -DLLVM_BUILD_GLOBAL_ISEL -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS
$
Looking at the cygwin header files, they automatically #define
these same macros before the '#include <stdint.h>', so this
addition to the Makefile is not required there ... :-D
[assuming that works for you, of course! hint, hint ;-) ]
