Please excuse me if this question has already been answered. But unfortunately
I have not been able to find a clear statement.
Why is RTEMS _XOPEN_SOURCE not set with a value when building a BSP with
--enable-posix?
in the rtems-libbsd you can find a definition in some places.
z.B. in dhcpd/configure -D_XOPEN_SOURCE=700 and
in glibc-bugs.h #define _XOPEN_SOURCE 500
…
That seems a little unstructured to me. I'm sure there's an explanation why
this is so complicated. But which value is the correct one e.g. for PowerPC and
RTEMS 5.1?
the so called feature test macros should be defined by the application:
https://www.gnu.org/software/libc/manual/html_node/Feature-Test-Macros.html
https://man7.org/linux/man-pages/man7/feature_test_macros.7.html
Which function is not defined in your setup?
