Hello William, Here is an extended snippet of code from configure.ac (including my changes): dateopt='' if test -n "$SOURCE_DATE_EPOCH" ; then if date --version | grep -q GNU ; then dateopt="-u -d @$SOURCE_DATE_EPOCH" else dateopt="-u -r $SOURCE_DATE_EPOCH" fi fi dnl for the man page DATE="`date $dateopt '+%a %d %B %Y'`" AC_DEFINE_UNQUOTED([BUILD_DATE], ["$DATE"], [Use reproducible build date]) AC_SUBST(DATE) As you can see, the purpose of the dateopt variable is precisely to pass the correct parameters...

Remove non-Posix use of FTW_ACTIONRETVAL

Going to close this because oprofile, commit 5ed9bda8baf7465172a99ff86ed7f46397b06c7f addresses this.
-
The limitation to this approach is that builds are only repeatable if they are built in the same day. Maybe something like https://reproducible-builds.org/docs/source-date-epoch/ would provide more reproducible builds. Also reproducible is spelled as "reproducidle" in 0e4969.

Dan Fandrich posted a comment on ticket #292
master as of now compiles fine for me with binutils 2.34 and 2.33.
-
Could you try the current master branch of oprofile and verify that this fixes the reported problem?
-
There are still a number of distributions that have older bersions of binutils. This needs to be conditional so oprofile can be compiled with the older binutils. Should have a set of wrapper defines in another header file and have a a test in configure.ac to select the correct wrappers. I have put a patch that does that on https://sourceforge.net/p/oprofile/oprofile/ci/bfd234/tree/ The patch allow oprofile to build on fedora 30 (binutils 2.31) and fedora rawhide (binutils 2.34). If the patch looks...

Macro wrappers to handle the binutils 2.34 api changes

This patch fixes the build for me using binutils 2.34. It will cause compile failures for previous versions, so it needs to be made conditional if compatibility with older versions is needed.

Hi William, Yes I too grep from the same and found none, but I could see the profiling works good when the version was downgraded to 1.1.0. Just added the profiling tools and oprofile from meta-Openembedded in yocto & selected oprofile from Buildroot. Found the same issue. Here is the log; root@beaglebone-yocto:~# strace operf --version execve("/usr/bin/operf", ["operf", "--version"], 0xbec3ad94 /* 15 vars */) = 0 brk(NULL) = 0x50c000 uname({sysname="Linux", nodename="beaglebone-yocto", ...}) = 0...

Hi, I too grep for the same and didn't get any way to trace this. I just build the package from Yocto (meta-openembedded) and buildroot both, which yields the same. If you go back to installing oprofile-1.1.0 everything works fine? Yes with the same build system for 1.1.0 was working good. Find the attached strace log and which operf
-
It doesn't look like "Operation not support" is coming from operf. The message doesn't seem to be in the oprofile source code. could you do a "which operf" to check to see which operf is being run? Could you give more destails on how oprofile-1.3.0 was built and installed on the machine? Where is oprofile installed on the machine? You might try to use the full path to make sure that the desired one is being used. Is it possible run "strace operf --version" to get a better idea when and where things...

The second patch can be used to force the error seen by the user. It is for testing purposes only and is not be committted to the repository. Will, let me know if you can read the patches OK or not. Thanks.
-
Per Will's request, I am attaching the two patches separately. The first patch is the fix for the issue.
-
Could you separate the the test and the actual fix in the patch into two separate patches? Right now they are all combined and done want that for the actual commit. The logic looks reasonable but would like to test thing a bit with the split patches.

The first issue noted was perf failed to start with "ocount --system-wide -e PM_L1MISS_LAT_EXC_32". Tested on a Power 8 system: /pe_counting# ocount --system-wide -e PM_L1MISS_LAT_EXC_32 ocount: Press Ctl-c or 'kill -SIGINT 122560' to stop counting ^C Events were actively counted for 3.3 seconds. Event counts (actual) for the whole system: Event Count % time counted PM_L1MISS_LAT_EXC_32 101,107 100.00 That does give non zero results, no perf errors. I tried the 256, 1024 and 2048 events as well and...

yes, the gcc patch is working nicely for us there, so no further effort required.
-
According to https://wiki.debian.org/ReproducibleBuilds/TimestampsFromCPPMacros The DATE and TIME defines are already addressed by a patch to gcc.
-
A similar change is needed in libutil/op_version.c replacing the c preprocessor DATE and TIME defines. There was some earlier discussion on the mailing list on this, should revise that work to use the DATE from the configure.
