but hashcat building seems right..

I also met this problem before.
This works for me.
1.Uninstall your hashcat first(I have installed hashcat via homebrew) - brew uninstall hashcat
2.git clone hashcat & git submodule update
3.Set SHARED to 1 in src/Makefile
4.make & make install
5.cp -r include/ /usr/local/include/hashcat
After these I can make build in gocrack
Before you build you have to ensure there have "gocat" and "zerolog" in your $GOPATH$

@EasyTraveller's instructions should fix it as it sounds like hashcat is not built as a shared library. (They're documented on this page https://github.com/fireeye/gocrack/blob/master/docs/building.md#step-1-building-hashcat).

You'll also want to make sure the code lives in a proper go workspace (as defined by the GOPATH environment variable). Mine is set to GOPATH="/Users//code/golang/" and the code should be in "/Users//code/golang/src/github.com/fireeye/gocrack". go get -u github.com/fireeye/gocrack should take care of downloading and setting up that folder hierarchy and will most likely complain about no buildable files but that can be ignored.
