           Product: clang

While trying to build LLVM/clang I get a compilation error that appears to
indicate that clang cannot find the appropriate C++ header files.

I hard-coded the path as suggested on http://clang.llvm.org/get_started.html:

syddev-build64-1>> grep /usr/local/gcc-4.6.2/include/c++/4.6.2
../tools/clang/lib/Frontend/InitHeaderSearch.cpp
      AddPath("/usr/local/gcc-4.6.2/include/c++/4.6.2", System, true, false,
false);
syddev-build64-1>> d /usr/local/gcc-4.6.2/include/c++/4.6.2/{new,algorithm}     
-rw-r--r-- 1 root root 2.6K Jan 13 14:31
/usr/local/gcc-4.6.2/include/c++/4.6.2/algorithm
-rw-r--r-- 1 root root 3.7K Jan 13 14:31
/usr/local/gcc-4.6.2/include/c++/4.6.2/new

& rebuilt from scratch, but it appeared to make no difference to the error:


  COMPILE:   clang_linux/asan-x86_64/x86_64:

Any pointers muchly appreciated.

Scott.
