This usually means that your header search paths are not configured properly. \
|
|
The header search paths should contain the C++ Standard Library headers before \
|
|
any C Standard Library, and you are probably using compiler flags that make that \
|
|
not be the case.

// This LWG issue deprecates the POSIX macros ENODATA, ENOSR, ENOSTR, and ETIME. These were
|
|
// deprecated in libc++ in https://github.com/llvm/llvm-project/pull/80542.
|
|
// Based on the post commit feedback the macro are no longer deprecated.
|
|
// Instead libc++ leaves the deprecation to the provider of errno.h.
