To be able to cross-compile for Linux, the main requirement is the GTK+ library, which provides the widgets for andlabs UI on Linux. Installing this is a little more difficult as the operating systems don't come with a standard package manager, but if you follow the steps described here it should be possible. The process also involves installing the cross-compiling toolchain, much like other examples in this section. The details for setting up cross-compilation can be found in Cross compiling for Linux with CGo section given in the Appendix, Cross-Compiler Setup. The main steps are outlined here for quick reference.
