Messages in this thread Patch in this message | ![/](/images/icornerl.gif) | | From | Zhangjin Wu <> | Subject | [PATCH v3 03/14] selftests/nolibc: add _LARGEFILE64_SOURCE for musl | Date | Fri, 30 Jun 2023 22:44:56 +0800 |
| |
_GNU_SOURCE Implies _LARGEFILE64_SOURCE in glibc, but in musl, the default configuration doesn't enable _LARGEFILE64_SOURCE.
From include/dirent.h of musl, getdents64 is provided as getdents when _LARGEFILE64_SOURCE is defined.
#if defined(_LARGEFILE64_SOURCE) ... #define getdents64 getdents #endif
Let's define _LARGEFILE64_SOURCE to fix up this compile error:
tools/testing/selftests/nolibc/nolibc-test.c: In function ‘test_getdents64’: tools/testing/selftests/nolibc/nolibc-test.c:453:8: warning: implicit declaration of function ‘getdents64’; did you mean ‘getdents’? [-Wimplicit-function-declaration] 453 | ret = getdents64(fd, (void *)buffer, sizeof(buffer)); | ^~~~~~~~~~ | getdents /usr/bin/ld: /tmp/ccKILm5u.o: in function `test_getdents64': nolibc-test.c:(.text+0xe3e): undefined reference to `getdents64' collect2: error: ld returned 1 exit status
