Bug ID: 23691
Summary: clang ignores --sys-root when looking for libc++
headers
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: [email protected]

Classification: Unclassified
When trying to cross-compile a C++ application using libc++, clang includes
libc++ headers from the system instead of the target sysroot.
For example, trying to cross-compile something that does "#include <string>"
with
clang -target x86_64-openmandriva-linux-musl -std=c++11 -stdlib=libc++ test.cpp
--sysroot=/usr/x86_64-openmandriva-linux-musl/sys-root -lc++ -lc++abi
will include
/usr/bin/../include/c++/v1/string
even if /usr/x86_64-openmandriva-linux-musl/usr/include/c++/v1/string exists.
