Subject: selftests: filesystems/epoll: fix build error
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7648dd9fc981cec52df8a635fa2eefc249e138b9;p=linux.git

selftests: filesystems/epoll: fix build error

epoll build fails to find pthread lib. Fix Makefile to use LDLIBS
instead of LDFLAGS. LDLIBS is the right flag to use here with -l
option when invoking ld.

gcc -I../../../../../usr/include/  -lpthread  epoll_wakeup_test.c  -o .../tools/testing/selftests/filesystems/epoll/epoll_wakeup_test
/usr/bin/ld: /tmp/ccaZvJUl.o: in function `kill_timeout':
epoll_wakeup_test.c:(.text+0x4dd): undefined reference to `pthread_kill'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x4f2): undefined reference to `pthread_kill'
/usr/bin/ld: /tmp/ccaZvJUl.o: in function `epoll9':

/usr/bin/ld: epoll_wakeup_test.c:(.text+0x6626): undefined reference to `pthread_join'
/usr/bin/ld: epoll_wakeup_test.c:(.text+0x684c): undefined reference to `pthread_tryjoin_np'
