[ Upstream commit bf561d3c13423fc54daa19b5d49dc15fafdb7acc ]
While cross building perf to the ARC architecture on a fedora 30 host,
we were failing with:
CC /tmp/build/perf/bench/numa.o
bench/numa.c: In function ‘worker_thread’:
bench/numa.c:1261:12: error: ‘RUSAGE_THREAD’ undeclared (first use in this
function); did you mean ‘SIGEV_THREAD’?
getrusage(RUSAGE_THREAD, &rusage);
^~~~~~~~~~~~~
SIGEV_THREAD
bench/numa.c:1261:12: note: each undeclared identifier is reported only once
for each function it appears in
[perfbuilder@60d5802468f6 perf]$
/arc_gnu_2019.03-rc1_prebuilt_uclibc_le_archs_linux_install/bin/arc-linux-gcc
--version | head -1
arc-linux-gcc (ARCv2 ISA Linux uClibc toolchain 2019.03-rc1) 8.3.1 20190225
[perfbuilder@60d5802468f6 perf]$
Trying to reproduce a report by Vineet, I noticed that, with just
cross-built zlib and numactl libraries, I ended up with the above
failure.
So, since RUSAGE_THREAD is available as a define, check for that and
numactl libraries, I ended up with the above failure.
So, since RUSAGE_THREAD is available as a define in the system headers,
check if it is defined in the 'perf bench numa' sources and define it if
not.
Now it builds and I have to figure out if the problem reported by Vineet
only takes place if we have libelf or some other library available.
