fix compilation on musl

[classabbyamp]

this should allow for compilation on musl libc

possibly fixes #150

[wb2osz]

I have a simpler solution to the first part. Simply use:

    qsort (tocalls, num_tocalls, sizeof(struct tocalls_s), tocall_cmp);

gcc does not complain about the missing type cast. Don't recall why I put it in there.

cmake tests whether the runtime library contains strlcpy and strlcat.
This determines whether we include our own copy.
We should be able to use result of that test rather than listing all of the possible operating system variations.

To be continued...

updated to address the first comment.

cmake tests whether the runtime library contains strlcpy and strlcat

I couldn't find this in any of the cmake files. Can you point it out to me?

[wb2osz]

The "dev" development branch already has this in direwolf.h

#ifndef HAVE_STRLCPY // Need to supply our own.
...
#define strlcpy(dst,src,siz) strlcpy_debug(dst,src,siz)
size_t strlcpy_debug(char *restrict dst, const char *restrict src, size_t siz);
...
#endif

Were you using the "master" branch?

[classabbyamp]

yes I was basing the PR on master. so that change won't be needed?

[wb2osz]

Try the "dev" branch.
My convention is to do development on "dev" and push to master when I have something stable.

[wb2osz]

Oops. I meant merge to master. Need to be more careful about terminology.

[classabbyamp]

Ok I see you've pulled in the change to dev in 59288b7, I'll close this now

[wb2osz]

Thanks for helping to make this more portable.

No problem! I'm trying to get direwolf accepted into void linux's repositories in void-linux/void-packages#37147
