tools lib traceevent: Remove libtraceevent

2022-12-14T14:16:12Z

libtraceevent is now out-of-date and it is better to depend on the system version. Remove this code that is no longer depended upon by any builds. Committer notes: Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so that 'make perf-tar-src-pkg' works.

tools lib traceevent: Make install_headers clearer

2022-11-20T14:32:23Z

Add libtraceevent to the name so that this install_headers build appears different to similar targets in different libraries. Add ; after kbuffer.h install target for consistency.

libtraceevent: Allow custom libdir path

2019-12-16T16:40:26Z

When I use prefix=/usr and try to install libtraceevent in my laptop it tries to install in /usr/lib64. I am not having any folder as /usr/lib64 and also the debian policy doesnot allow installing in /usr/lib64. It should be in /usr/lib/x86_64-linux-gnu/. Quote: No package for a 64 bit architecture may install files in /usr/lib64/ or in a subdirectory of it. ref: https://www.debian.org/doc/debian-policy/ch-opersys.html Make it more flexible by allowing to mention libdir_relative while installing so that distros can mention the path according to their policy or use the default one.

libtraceevent: Copy pkg-config file to output folder when using O=

2019-12-03T00:58:20Z

When we use 'O=' with make to build libtraceevent in a separate folder it still copies 'libtraceevent.pc' to its source folder. Modify the Makefile so that it uses the output folder to copy the pkg-config file and install from there.

libtraceevent: Fix lib installation with O=

2019-12-03T00:58:20Z

When we use 'O=' with make to build libtraceevent in a separate folder it fails to install libtraceevent.a and libtraceevent.so.1.1.0 with the error: INSTALL /home/sudip/linux/obj-trace/libtraceevent.a INSTALL /home/sudip/linux/obj-trace/libtraceevent.so.1.1.0 cp: cannot stat 'libtraceevent.a': No such file or directory Makefile:225: recipe for target 'install_lib' failed make: *** [install_lib] Error 1 I used the command: make O=../../../obj-trace DESTDIR=~/test prefix==/usr install It turns out libtraceevent Makefile, even though it builds in a separate folder, searches for libtraceevent.a and libtraceevent.so.1.1.0 in its source folder. So, add the 'OUTPUT' prefix to the source path so that 'make' looks for the files in the correct place.

libtraceevent: Fix header installation

2019-11-22T13:48:14Z

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

2019-09-25T12:51:43Z

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

2019-08-20T15:18:54Z

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.
