/home/onodera/tmp/new/src/factor/primes.h:47:9: error: unknown type name 'u_int32_t'

```/home/onodera/tmp/new/src/factor/factor.c:79:8: error: unknown type name 'u_int64_t'

      |        ^~~~~~~~~

Seems like uint32_t and uint64_t should be used and is the standard type. See https://lists.freedesktop.org/archives/release-wranglers/2004-August/000923.html

#include <stdint.h> should also be added to primes.h, to include the type.

   99 |       (append ? O_APPEND : O_TRUNC), DEFFILEMODE)) == -1) {
      |

Some patch for another program I found (https://www.linuxtv.org/pipermail/vdr/2017-January/029221.html) fixed it by adding this ifdef:

#ifndef DEFFILEMODE
# define DEFFILEMODE (S_IRUSR|S_IWUSR|S_IRGRP|S_IWGRP|S_IROTH|S_IWOTH)/* 0666*/
#endif

There are a lot more errors, I might try creating a patch this week, but I am not an expert with C.

@onodera-punpun Try installing these packages and seeing if it'll compile:
Musl-FTS https://github.com/pullmoll/musl-fts
Musl-Obstack https://github.com/pullmoll/musl-obstack
Musl-RPmatch https://github.com/pullmoll/musl-rpmatch
Musl-Legacy-Compatibility Headers https://github.com/void-linux/void-packages/blob/master/srcpkgs/musl-legacy-compat
Argp-Standalone https://github.com/jahrome/argp-standalone

These packages may also be of interest:
gCompat https://code.foxkit.us/adelie/gcompat
Locales https://github.com/rilian-la-te/musl-locales

Hopefully that helps :)

Sorry for the late reply, do you have any distro you are using musl reference so I can test?

I didn't get notified by GitHub so thats why I didn't reply, sorry!

[DiegoMagdaleno]

Hi @onodera-punpun @saltedcoffii just to confirm I will start working on this issue tomorrow on void linux musl

[DiegoMagdaleno]

I have done quite a lot of progress today, some tools have some musl-c changes that need to be done, and require more complex patches, this being one of them.

I hope I can have fixes by tomorrow :)

[DiegoMagdaleno]

Now it builds on musl_c without any issues! :D
