What is this supposed to do?!

Why are you doing this?

Why are you saying where to install C++ headers if you're disabling libstdc++?

It's unclear what you're trying to do, and what fails. We can't help
you without more information.
What do you mean by "i still fail"? Was it working with 11.1.0 or not?
Is this a new error with 11.5.0?

I've never seen this error before and don't know why it happens. It
seems related to this line of code:
#ifdef _GLIBCXX_PTRDIFF_T_IS_INT
_GLIBCXX_APPLY_SYMVER(_ZNSi8ignoreXXEi, _ZNSi6ignoreEi)
#else
_GLIBCXX_APPLY_SYMVER(_ZNSi8ignoreXXEl, _ZNSi6ignoreEl)
#endif
If this is going wrong, it suggests PTRDIFF_T_IS_INT is wrong, which
suggests some problem in your configuration.
Are you messing with the c++config.h header during the build?
