I cannot get it to compile in linux. I would like to know if it is supposed to, before digging any further.
$ uname -a
Linux hostname 5.2.9-arch1-1-ARCH #1 SMP PREEMPT Fri Aug 16 16:24:43 UTC 2019 x86_64 GNU/Linux
$ git clone https://github.com/wtfutil/wtf
[...]
$ cd wtf
$ make
[...]
$ ./bin/wtfutil
seems to work fine here
