Subject: [PATCH] selftests: filesystems/epoll: fix build error
Date: Tue, 10 Dec 2019 17:12:33 -0700 [thread overview]
Message-ID: <20191211001233.15084-1-skhan@linuxfoundation.org> (raw)
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':
