How can I configure clang to use “-stdlib=libc++” by default instead of libstdc++?
If it’s not possible, can I compile my own version to do it?
I found a place suggested running this command to compile clang for this purpose:
…/llvm/configure CXXFLAGS="-stdlib=libc++ -std=c++11" OBJCXXFLAGS="-stdlib=libc++ -std=c++11" LDFLAGS="-stdlib=libc++"
But I see that the autoconf build system is deprecated.
Is there a cmake alternative for that command?
Or any other way to make clang use libc++ by default?
