Subject: [PATCH v3 0/5] Support perf -vv
Date: Thu, 29 Mar 2018 22:56:17 +0800 [thread overview]
Message-ID: <1522335382-11983-1-git-send-email-yao.jin@linux.intel.com> (raw)
We keep having bug reports that when users build perf on their own,
but they don't install some needed libraries such as libelf,
libbfd/libibery.
The perf can build, but it is missing important functionality. And
users may complain that perf has issue or bug.
This patch-set support to print the status of compiled-in libraries.
Once users think perf missing some functionality, it should be very
easy for them to check the libraries status.
For example:
$ ./perf version --build-options
or
./perf --version --build-options
or
./perf -v --build-options
or
./perf -vv
perf version 4.13.rc5.g4c1df1
