Due to the dependency on CGo, compiling for a platform other than the one you are developing in is, unfortunately, not as simple as setting the GOOS environment variable. Building for a different platform requires an installation of the C compiler for the target operating system. If you've been working through the previous chapters, then this may already be set up, but if not, then the process is documented in Appendix 2, Cross-Compiler Setup.

Once you have the appropriate compiler installed, then the build process is configured by setting the GOOS, CGO_ENABLED, and CC environment variables. You may also need to update your path—it's advisable to put this in your Terminal or shell configuration:

Now that we've explored the details of getting up and running and compiling for multiple platforms, let's look more at how Fyne is designed and organized.
