FTBFS on Unity Linux (musl-libc) due to usage of qsort_r (hawkey code issue) about libdnf HOT 6 CLOSED

Why are we using qsort_r() and not just qsort()? Given we now depend on Glib, it would also be interesting if any of the sorting callbacks can be used with qsort().

@hughsie I dunno. If you can fix it without me having to use libsolv's qsort_r implementation, I'm cool with that.

(The easiest fix is probably to switch to solv_sort in hawkey)

from libdnf.

@mlschroe So your solv_sort() function is exported and available for consumers of libsolv to use? If that's the case, then that might be the appropriate solution, as it would also ensure that libsolv and hawkey/libhif are always using the same qsort_r implementation.

What do you think, @hughsie?

from libdnf.

Makes sense to me.

from libdnf.

@hughsie If you could go ahead and switch hif/hawkey to use solv_sort() from libsolv in place of qsort_r(), that would solve the problem.
