Right now when started not from system path like /bin or /usr/bin, the tool argues that it cannot locate include files stddef.h, stdint.h etc. when parsing system headers like <iostream>. This of course causes mayhem and incorrect behavior.

The issue is related to clang builtin includes. To quote:

the default location to look for builtin headers is in a path $(dirname /path/to/tool)/../lib/clang/3.3/include relative to the tool binary. This works out-of-the-box for tools running from llvm’s toplevel binary directory after building clang-headers, or if the tool is running from the binary directory of a clang install next to the clang binary.

Another clue from pro.cxx

it is not /usr/bin, it is clang-install-dir wherever you've installed it, it is considered as root, since that's the way relocatable toolchain is done in LLVM

• Search for <string> in /arm/target/usr/include instead of /usr/include
• Prevent clang builtin limits.h #include_nexting /usr/include/limits.h

• run on everything from compile database
• apply changes automatically (+ --no-confirmation); any parse errors at any stage should prevent changes being applied
• display results (for tests)

• Build
• Tests

Requires:

• #3 tests to perform
• #1 ability to install / or #6 run from build directory
