Hi,

When I tried to compile a piece of c++ code

  clang++ -std=c++0x -I/usr/include/c++/v1/ ./variadic_print.cpp  -lc++

the linker was unable to resolve the symbol clock_gettime.
Of course, it's in librt.so, so simply appending -lrt fixes the problem.

Does libc++ itself depend on librt?
I built libc++ by CMake using clang compiler instead of gcc.

Thanks,

Ryuta
