gfapi.Volume not defined error when attempting to cross compile

[chrisbecke]

Problem

Building the sample main.go from the README.md on MacOS I get the following result:

$ go build
# pkg-config --cflags  -- glusterfs-api glusterfs-api glusterfs-api
Package glusterfs-api was not found in the pkg-config search path.
Perhaps you should add the directory containing `glusterfs-api.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glusterfs-api' found
Package glusterfs-api was not found in the pkg-config search path.
Perhaps you should add the directory containing `glusterfs-api.pc'
to the PKG_CONFIG_PATH environment variable

pkg-config: exit status 1

Ok. It seems that glusterfs-api is not available natively for Mac. Perhaps I can try cross compile the binary for a linux image:

$ GOOS=linux GOARCH=amd64 go build
# main 
./main.go:6:10: undefined: gfapi.Volume

Steps to replicate

1. a test go project was created as per the instructions on github.com/gluster/gogfapi
2. GOOS=linux GOARCH=amd64 go build was executed to do the build
