Oh, another #include <unistd.h> thing I bet! Happened with compface yesterday.

unistd.h does not define exit()
; stdlib.h does. For each implicit declaration of function, it must be researched what the correct header is and the correct include must be added to the applicable code.
Duplicate of #61383.
Note: See
TracTickets for help on using
tickets.
It is perfectly fine and accurate that features.h is not found. configure scripts test for the presence of various files and features to decide how to build on your system. Because it could not find features.h, it inferred that your system is not a GNU libc system, which is correct; macOS does not use glibc.
The real problem is that the writers of the configure script forgot to include essential headers, like those that define the
exit()
function, hence some later test fail unintentionally witherror: implicitly declaring library function 'exit'
. That's what needs to be fixed.
