Question

LLVM 2.6 + clang.

Trying to compile C++ file and got:

clang: warning: not using the clang compiler for C++ inputs

How can I start clang in C++ mode?

Was it helpful?

Solution

I would get the trunk code. C++ support has been much improved since 2.6.

The clang driver Makefile in tools/clang/tools/driver uses the CLANG_IS_PRODUCTION define to control whether C++ is on or off. CLANG_IS_PRODUCTION means C++ off. The default for a trunk build is no CLANG_IS_PRODUCTION (i.e. a development build).

OTHER TIPS

I know that the trunk code has c++ enabled. Perhaps you could use that instead?
