Plugin cannot be added to xfce panel emerging the following error in ~/.xsession-errors: (process:20922): xfce4-panel-wrapper-CRITICAL **: Wrapper diskperf-9: Failed to open plugin module "/usr/lib64/xfce4/panel/plugins/libdiskperf.so": /usr/lib64/xfce4/panel/plugins/ libdiskperf.so: undefined symbol: major.

Though i'm not gentoo dev, i confirm - after last upgrade to gcc-7.3.0/binutils-2.30.1 diskperf plugin loading fails with this error. However, rebuilding it again with gcc-6.4.0 doesn't fix problem. Btw, if you look plugin binary in mcview, 'major' symbol appears there, while in some other plugins (xfce powermanager) it absents. Also "nm" says "no symbols".
Hm... i said i confirm... Caption is "fails to build", but actually it builds, while simply refuses to run, but with exactly same error.
(In reply to Nikita Zlobin from comment #3) > Caption is "fails to build"... The bug title is correct.
Thank you for the report. Please recompile and *attach* the logfiles as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket The logs must be part of the ticket, but not on external websites. Please reopen this ticket (Status:unconfirmed) afterwards.

It appears, but it is undefined: $ nm -CD /usr/lib64/xfce4/panel/plugins/libdiskperf.so | grep major U major Here is a similar bug: https://github.com/hishamhm/htop/issues/663. Looks like source files lack including sysmacros.h: https://github.com/lattera/glibc/blob/master/sysdeps/unix/sysv/linux/sys/sysmacros.h#L66.
The fix from mgorny: https://github.com/xfce-mirror/xfce4-diskperf-plugin/commit/0787a8972be2b95fac26c502a82427299e7e48c0. It was committed to the master branch, but not merged into any stable version (the latest -- 2.6.1 -- doesn't include it). :(
Possibly, we may now add a patch (until upstream is fixed in some stable version): https://bugzilla.xfce.org/show_bug.cgi?id=13940#c5.
I confirm this bug on my AMD64, having gcc-7.3.0-r4. Compiles, but cannot run.
I'm sorry that I've forgotten to deal with this earlier. Upstream apparently isn't going to make a new release, so I'm going to apply the simpler version of my patch (one that doesn't require eautoreconf).
