Can't compile with localization disabled

[sa2thoms]

My use-case for this library is an embedded application where we have localization disabled (by defining __LIBCPP_HAS_NO_LOCALIZATION). This causes problems when compiling with mp-units, as it tries to include the iostream library. Is there any way to build the library without these parts?

Hi, thanks for your feedback!

We had such separations of compilation before we added support for C++ modules in the last version. However, with modules, it didn't scale, so we do not have separate I/O CMake targets anyway. We decided that we would add conditional compilation for a freestanding part when the need arises. And here it is... 😉

As of today, there is no separation, but I would like to add it. The only problem is that enforcing freestanding mode is non-standard and not even well defined in implementations (e.g., _LIBCPP_HAS_NO_LOCALIZATION is not equivalent to a freestanding mode).
