Subject: [PATCH] Unconditionally define _GNU_SOURCE
|
|
|
|
uClibc also uses _GNU_SOURCE to expose glibc compatible API extensions.
|
|
But toolchain built with uClibc don't define __gnu_linux__. This leads
|
|
to implicit declaration warnings at build time. With GCC 14 these
|
|
warnings become errors by default.
|
|
|
|
For example:
|
|
|
|
.../sexpect-2.3.14/server.c: In function 'expect_exact':
|
|
.../sexpect-2.3.14/server.c:630:17: error: implicit declaration of function 'strcasestr'; did you mean 'strcasecmp'?
|
|
[-Wimplicit-function-declaration]
|
|
630 | found = strcasestr(g.expbuf, g.conn.pass.pattern);
|
|
| ^~~~~~~~~~
|
|
| strcasecmp
|
|
|
|
Define _GNU_SOURCE unconditionally to fix the build.
