then the compiler hangs indefinitely. OS X 10.11.1, LLVM 3.6.2

Thanks John for testing and sorry for the bumpy ride,

The default include paths Clang is looking into look incorrect. You can see the paths with -cpp-args -v (makes Clang verbose during PCH generation), could you check out what's wrong or missing?

[John-Colvin]

-cpp-args -v -std=c++11 didn't work (it didn't recognise -std=c++11), nor did -ccp-args -v -cpp-args -std=c++11 (it seemed to ignore -v), but just -cpp-args -v gave me

Where are your C++ standard lib headers located? As a workaround to the broken detection you can manually add the path with -cpp-args -isystem -cpp-args /path/to/libc++headers so cstddef may be found.

-cpp-args -v -cpp-args -std=c++11 should work btw, the purpose of -cpp-args is to append each following argument to the Clang "command line".

I tried this Quantlib example on OS X also and I can't get it to work either. Some parts of Quantlib work on Linux and I tried to just copy over the build file and test file (minimal as above), but I ran into the same errors.

Trying to add '-cpp-args -I/usr/local/opt/llvm/include/c++/v1' to my command line ends up with strange control characters being printed ... along with 'error' like this:

Seems like something is going wrong with -cpp-args and arguments with a '/' in them??? Maybe? I tried a couple other options with '/' and the same thing happens.

I might try to look into this further, if you can't think of anything off hand that could lead to this Elie.

It seems like Clang is reading a binary file instead of a header.

A similar situation happens with the qt5demo also :(
