Hi,
I'm maintainer of erofs-utils for Alpine linux, distribution which use
musl libc instead of glibc.
Building version 1.8.6 gives error:

------------------
This is because musl use readdir, pread and lseek instead of readdir64,
pread64 and lseek64.
(IMO musl does this properly)
Natanael Copa <nc...@alpinelinux.org> created patch with which I build
erofs-utils successfully. I'm attaching patch to this mail.
Feel free to contact me if you more information or to try some new
patches.
Thanks! I will look into that later and feedback.
Thanks,
Gao Xiang
