Issue compiling using Burrito and Zig

[m0rt3nlund]

Hi!

I am trying to compile this project as it is part of the Elixir Ash library.

I am compiling it using Burrito which is using Zig (Mingw)

I have tried to make my own .h files that link to the files inside Zig but it is a never ending rabit hole as file x links to y and y to z and so on...

This is the output I get:

I was able to compile it when I added -DNGETRUSAGE=1 to the CFLAGS for Linux

I am not sure how to fix this in a way to allow it to be compiled by Zig though.. I guess this is happening because the Makefilx.win does not apply when compiling picosat_elixir when the host is linux and the target is Windows. Somehow..

UNAME_SYS := $(shell uname -s)
ifeq ($(UNAME_SYS), Darwin)
    CFLAGS := -std=c99 -finline-functions -Wall
    LDFLAGS := -flat_namespace -undefined suppress
else ifeq ($(UNAME_SYS), FreeBSD)
    CFLAGS := -std=c99 -finline-functions -Wall
else ifeq ($(UNAME_SYS), Linux)
    CFLAGS := -std=c99 -finline-functions -Wall -DNGETRUSAGE=1
endif
