Subject: selftests: mm: fix undeclared function error
Date: Wed, 17 Apr 2024 12:55:30 +0500
Fix the error reported by clang:
In file included from mdwe_test.c:17:
/../kselftest_harness.h:1169:2: error: call to undeclared function
'asprintf'; ISO C99 and later do not support implicit function
declarations [-Wimplicit-function-declaration]
1169 | asprintf(&test_name, "%s%s%s.%s", f->name,
| ^
1 warning generated.
The gcc reports it as warning:
In file included from mdwe_test.c:17:
./kselftest_harness.h: In function `__run_test':
./kselftest_harness.h:1169:9: warning: implicit declaration of function
`asprintf'; did you mean `vsprintf'? [-Wimplicit-function-declaration]
1169 | asprintf(&test_name, "%s%s%s.%s", f->name,
| ^~~~~~~~
| vsprintf
Fix this by setting _GNU_SOURCE macro needed to get exposure to the
asprintf().
