- Subject: [PATCH] Define _GNU_SOURCE when needed
- Define _GNU_SOURCE to fix build with musl otherwise we'll got the
- following build failures due to localtime_r, strnlen, gmtime_r and
- asctime_r being undefined:
- os/localtime_s.c:124:12: error: implicit declaration of function 'localtime_r'; did you mean 'localtime_s'? [-Werror=implicit-function-declaration]
- dest = localtime_r(timer, dest);
- ^~~~~~~~~~~
- io/gets_s.c:144:32: error: implicit declaration of function 'strnlen'; did you mean 'strlen'? [-Werror=implicit-function-declaration]
- rsize_t len = (rsize_t)strnlen(dest, dmax);
- ^~~~~~~
- strlen
- An other option would be to define AC_GNU_SOURCE in the configure.ac but
- it seems that there is some handling of _GNU_SOURCE in
- safeclib_private.h
- Fixes:
- - http://autobuild.buildroot.net/results/31a4b647ec0dcd9f517f313ec6c7c8f56da1ee47
