[cfe-dev] [libcxxabi] Which unwind.h?

[Ryuta Suzuki]

Hi,

When I tried to build libcxxabi by clang++, the compiler complained about
the missing header:

[ 12%] Building CXX object src/CMakeFiles/cxxabi.dir/cxa_exception.cpp.o
In file included from
/home/ryuta/devel/libcxxabi/src/libcxxabi/src/cxa_exception.cpp:21:
/home/ryuta/devel/libcxxabi/src/libcxxabi/src/cxa_exception.hpp:3:10: fatal
error:
      'unwind.h' file not found
#include "unwind.h"
         ^
1 error generated.
make[2]: *** [src/CMakeFiles/cxxabi.dir/cxa_exception.cpp.o] Error 1
make[1]: *** [src/CMakeFiles/cxxabi.dir/all] Error 2
make: *** [all] Error 2

Here's clang++'s search list:

#include "..." search starts here:
#include <...> search starts here:
 /usr/include/c++/4.6.1
 /usr/include/c++/4.6.1/backward
 /usr/include/c++/4.6.1/x86_64-unknown-linux-gnu/
 /usr/local/include
 /usr/bin/../lib/clang/3.0/include
 /usr/include
End of search list.

I see unwind.h in /usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.1/include.
Are we supposed to use this header file?
Any comments will be greatly appreciated.

Thanks,

Ryuta
