Bug ID: 26777
Summary: check-libcxx fails when built with CXX="ccache
clang++"
Product: libc++
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
If you use ccache to build libcxx by setting CXX="ccache clang++", check-libcxx
will fail since LIBCXX_COMPILER will be set to "ccache".
We can't just include CMAKE_CXX_COMPILER_ARG1 because of a python parsing
issue, so the best we can do right now is to use CMAKE_CXX_COMPILER_ARG1 if it
exists, and CMAKE_CXX_COMPILER if it doesn't.
