libtraceevent: Fix header installation

2019-11-22T13:48:14+00:00

When we passed some location in DESTDIR, install_headers called
do_install with DESTDIR as part of the second argument.

But do_install is again using '$(DESTDIR_SQ)$2', so as a result the
headers were installed in a location $DESTDIR/$DESTDIR.

In my testing I passed DESTDIR=/home/sudip/test and the headers were
installed in: /home/sudip/test/home/sudip/test/usr/include/traceevent.

Lets remove DESTDIR from the second argument of do_install so that the
headers are installed in the correct location.

libtraceevent: Move traceevent plugins in its own subdirectory

2019-09-25T12:51:43+00:00

All traceevent plugins code is moved to tools/lib/traceevent/plugins
subdirectory. It makes traceevent implementation in trace-cmd and in
kernel tree consistent. There is no changes in the way libtraceevent and
plugins are compiled and installed.

Committer notes:

Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf
target for the plugin dynamic list file. Problem noticed when cross
building to aarch64 from a Ubuntu 19.04 container.

tools lib traceevent: Fix "robust" test of do_generate_dynamic_list_file

2019-08-20T15:18:54+00:00

The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.

Add 'tr "w" "W"' to merge the two and not worry about the ordering.

The first man page is also part of the patch - summary of the library
and all its APIs.

Building of the documentation is integrated into the libtraceevent build
process, new targets are added to its Makefile:

tools lib traceevent: Remove hard coded install paths from pkg-config file

2019-05-15T19:36:46+00:00

Install directories of header and library files are hard coded in
pkg-config template file.

They must be configurable, the Makefile should set them on the
compilation / install stage.

So that the user can specify outside LDFLAGS values.

Keeping the CFLAGS in there as well, so we don't break existing scripts.

tools lib traceevent, tools lib lockdep: Rename 'enum pevent_errno' to 'enum tep_errno'

2018-08-13T18:23:07+00:00

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_" and not "pevent_". This changes
'enum pevent_errno' to 'enum tep_errno'.
