Subject: [PATCH 17/43] tools build: Add -lrt to FEATURE_CHECK_LDFLAGS-libaio
Date: Thu, 14 Feb 2019 21:45:13 -0300 [thread overview]
Message-ID: <20190215004539.23571-18-acme@kernel.org> (raw)
In-Reply-To: <20190215004539.23571-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Since we need it to resolve the AIO symbols, otherwise we fail with:
$ cat /tmp/build/perf/feature/test-all.make.output
/usr/bin/ld: /tmp/ccEqrj36.o: undefined reference to symbol 'aio_return64@@GLIBC_2.2.5'
/usr/bin/ld: //usr/lib64/librt.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
$
When we added the aio support in 'perf record' only the test-libaio.bin
target got the -lrt, i.e. the feature detection slow path. Fix it.
