i3 doesn't compile on musl

[nmeum]

i3 currently doesn't compile on a musl libc system. The only function that seem to cause troubles is the resolve_tilde function from libi3/resolve_tilde.c. This function uses GLOB_TILDE which is a GNUism and (probably) only available in glibc.

This is the output of make on the next branch:

I don’t see a link to logs.i3wm.org. Did you follow http://i3wm.org/docs/debugging.html? (In case you actually provided a link to a logfile, please ignore me.)

[i3bot]

I don’t see a version number. Could you please copy & paste the output of i3 --version into this issue?

GLOB_TILDE is not a GNU-ism, it’s also available on FreeBSD, NetBSD and other systems.

Please send a pull request if you care about getting this fixed.

I don't think there's any value in keeping a ticket open for this. As Michael pointed out, if you want this to be fixed, send a pull request.

I got this to compile and run for i3status 2.13 on alpine 3.10 by adding
#define GLOB_TILDE GLOB_PERIOD to the bottom of the config.h.in file

This is extremely hacky, but got it to compile and run. What would be the appropriate fix? I can implement it and submit a pull request.

[stapelberg]

The appropriate fix would be to re-implement the current behavior without using GLOB_TILDE.
