llvm dev - Jan 2013 - [LLVMdev] Fatal error in build, include <utility> not found

I'm trying to customize llvm by adding a header file of my own and tweaking
things accordingly.
While building, things go well until a certain point where it stops seeing
the includes of my file.

I'm working on Ubuntu 12.04 with llvm-3.1 on a custom target (mips-like),
gcc-4.6 and clang-3.2 (i've tried 3.1 too).
>From what i've understood, when it builds the first binaries of clang,it
switches to this in order to continue the build, consequently using the
includes found in build folder and ignoring the defaults (/usr/include,
/usr/include/c++/4.6, /usr/include/c++/4.6/x86_64-linux-gnu).
Is there a way to explicitly provide include directories at this point?

Thanks,
Andrew

Hi Andrew, I suggest you do a verbose build (make VERBOSE=1) in order to see
exactly which command is being used to compile that file.

Ciao, Duncan.

Hi Duncan,

I did. I know what the error is. It cannot see the include directories it
could see before (myfile.hpp is called again on previous code).
I even tried copying the utility file in build/include. It worked but hit
another include error because another directory could not be seen.
Obviously the solution is not to copy the entire directories to
build/include but make clang see them.

Well here's your problem! You're trying to include a C++ header (your
custom header, "llvm/Support/myfile.hpp") from a C header
(<llvm/Support/DataTypes.h>). There are a couple of ways you could solve
this: either don't include your custom header from DataTypes.h, or guard it
with an #ifdef __cplusplus block.

Thank you Charles. That was the problem. It compiled just fine.
Thanks again!
