Bug ID: 15885
Summary: Driver assumes libc++ headers in /usr/include, libc++
installs them into current install location
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Driver

possible patch for ToolChains.cpp
There is currently a mismatch between where the driver expects to find the C++
headers if the -stdlib=libc++ flag is used( /usr/include/c++/v1) and where a
libc++ 'install' actually installs them (
${CMAKE_INSTALL_PREFIX}/include/c++/v1 ).
If the driver and the libraries are explicitly installed into different places
then the user can be expected to have to supply correct -I and -L flags (or
there should be a option to point to a common install area).
For a simple install to a single area though, Things Should Just Work.
I have attached a patch for ToolChains.cpp that looks in the installation
directory, rather than the fixed location, though a more sophisticated system
could no doubt be devised.
