The lbench benchmark program is one SlackBuild that doesn't compile for
me on Slackware 15 or 15+current from SBo-git. Here's what it says
lbench-3.7/Makefile

I hope it will be updated but I also hope to see a version that
works on X/TWM, not only Wayland/GNOME. The lbench author told me GNOME
might take up 1% or 2% CPU system resources, but for me, that's too
much. When I run benchmarks I turn off all but certain hardware &
logging daemons... I guess because I'm more interested in mathematics
than engineering, that I want an accurate benchmark--to five numerical
places (as in science and professional engineering) not an approximation
to 98%.
Does the maintainer use this listserv, and what do they or anyone
think about that?
