Subject: [PATCH] configure: Include dirent.h for closedir/opendir APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
GCC-14 is strict about function prototypes and since the
testcase tries to compile/link opendir/closedir functions
without including signatures, it fails to build the test
due to missing signatures which come from dirent.h
Therefore include the needed system header and make it more
robust.
Fixes
a.c:2:21: error: implicit declaration of function ‘closedir’ [-Wimplicit-function-declaration]
2 | int main() { return closedir(opendir(".")); }
| ^~~~~~~~
a.c:2:30: error: implicit declaration of function ‘opendir’ [-Wimplicit-function-declaration]
2 | int main() { return closedir(opendir(".")); }
| ^~~~~~~
