There is a check for CTLL_CNTTP_COMPILER_CHECK, which hasn't been defined yet.

#if CTLL_CNTTP_COMPILER_CHECK
	#define CTLL_FIXED_STRING ctll::fixed_string
#else
	#define CTLL_FIXED_STRING const auto &
#endif

In what version is the error?

The version released in April

95c6386

there is a clang warning called -Wundef that shows these mistakes

I would suggest using -Werror=undef

I think you might have already fixed it, I'll have to check later.
