Add a shared library version, generating the following files:
$ ll tools/perf/lib/libperf.so*
libperf.so -> libperf.so.0.0.1
libperf.so.0 -> libperf.so.0.0.1
libperf.so.0.0.1
Committer testing:
One has to build just libbperf to get this, building perf so far doesn't
trigger this, i.e. I tried:
$ make O=/tmp/build/perf -C tools/perf
And the files above were not created, so one has to do:
$ make O=/tmp/build/perf -C tools/perf/lib/
make: Entering directory '/home/acme/git/perf/tools/perf/lib'
LINK /tmp/build/perf/libperf.so.0.0.1
make: Leaving directory '/home/acme/git/perf/tools/perf/lib'
$ ls -la /tmp/build/perf/*.so.*
lrwxrwxrwx. 1 acme acme 16 Jul 22 15:37 /tmp/build/perf/libperf.so.0 -> libperf.so.0.0.1
-rwxrwxr-x. 1 acme acme 16368 Jul 22 15:37 /tmp/build/perf/libperf.so.0.0.1
