Did you #include <string.h>
?
Ctrl+Shift-P → Rebuild Intellisense?
its not work. I have #include <string.h>
Weird, the declaration is within an ifdef block…
with __MISC_VISIBLE
, __POSIX_VISIBLE
etc. Those things are activated when the _GNU_SOURCE
macro is defined.
You can add
build_flags =
-D _GNU_SOURCE
to the platformio.ini
and reload intellisense
Then it should work.
Thank you, you are the best. I reinstalled the program and this was not the case on the same project before. In this case, the compilation completes normally
