Hmm, it seems like timeval should be supported even in MUSL LibC, do you think this is related?

quartzjer commented

Try again and let me know if that fixes it, I think it was just a missing include.

Ran

  1. git pull
  2. make clean
  3. make

I'm just guessing now, if this doesn't work I'll try to get musl-gcc working myself to reproduce :)

systmkor commented

Okay so after a little searching and asking. The definition is located in bits/alltypes.h line number 256.

quartzjer commented

I can clearly see the struct timeval being used in the official included sys/time.h, is it not in your local build system somehow?

http://git.musl-libc.org/cgit/musl/tree/include/sys/time.h

systmkor commented

It is in my local build system. bits/alltypes.h I tried compiling while including that header in unix/util.c however I keep getting the same error. I think I need to look through what the pre-processor generates.

systmkor commented

Just tried again from a clean start and it appears to compile correctly. Thanks 👍

Awesome!!
