musl does not implement qsort_r

[kyx0r]

There is a typo here: https://github.com/jdah/minecraft-weekend/blob/master/src/util/fmath.c#L21

should be < defined > instead of < define >.

The problem that qsort_r still remains unimplemented.

What platform are you on?

and good catch on the #define issue, fixed in 7914e92f0e66cfd644577cee154c314ef5e17a4e.

@jdah https://musl.libc.org/ Musl does not implement qsort_r.

[kyx0r]

Other than that the game works, I just built it against glibc in chroot and it works. But problem still remains on musl.

Maybe you can use this to implement qsort_r in the code? (didn't test it) https://gist.github.com/izabera/e68927258ad2d29a1586bad276fabcab
