[kostya]

seems it was renamed to dkstats.h

git clone https://github.com/kostya/sigar.git
cd sigar

Try replace #include <sys/dkstat.h> with #include <dkstats.h> and run rake build.
If it not work, try remove this line and find what methods use this, if methods not needed we can just remove them.

[kasak87]

unfortunately, replacing sys/dkstat.h with dkstats.h just throw same error with "dkstats.h not found"
removing this line causes huge amount of errors:

as i can see, openbsd guys changed dkstat.h to sched.h https://marc.info/?l=openbsd-tech&m=140999793929262&w=2

But changing this, did not fix the build, just removed some errors

[kostya]

i have no idea, for me looks like unfixable

[kostya]

probably you can try to remove all bugged code and probably it would be ok, because eye not used much methods.
