[R-pkg-devel] Can -mmacosx-version-min be raised to 10.15 ?

[Dirk Eddelbuettel]

Hi Simon,

We use C++20 'inside' our library and C++17 in the API. Part of our C++17 use
is now expanding to std::filesystem whose availability is dependent on the
implementation. 

The compiler tells us (in a compilation using -mmacosx-version-min=10.14)
that the features we want are only available with 10.15.

Would we be allowed to use this value of '10.15' on CRAN?

Thanks as always,  Dirk
