How to detect the libstdc++ version in Clang?
Clang does come with its own standard library implementation, it's called libc++. You can use it by adding
-stdlib=libc++ to your compile command.
That being said, there are various ways to check Clang/libstdc++ C++ support:
- Clang has the
__has_featuremacro (and friends) that can be used to detect language features and language extenstions.
- Libstdc++ has its own version macros, see the documentation. You'll need to include a libstdc++ header to get these defined though.
- GCC has its version macros which you already discovered, but those would need to be manually compared to the documentation.
And also, this took me 2 minutes of googling.
