Multi-package Makefile Example

[Mitchell Hashimoto]

Hi,

I'm currently working on a standalone application which is comprised of multiple packages. I was previously using godag for compilation (http://code.google.com/p/godag/) which is a fantastic tool. Unfortunately, this doesn't work with the latest weekly and I require the latest weekly for the database standard libraries. So now I think I'm stuck with moving back to Makefiles, but I can't find any up-to-date examples of a multi-package makefile for a project. The basic layout of the project is the following:

src/main.go

src/package_A/package_A.go

src/package_B/package_B.go

src/package_C/package_C.go

The packages may have dependencies on each other (but nothing circular), and main depends on all packages.

Can anyone point me in the right direction of where I can look into how to easily build this project?

Best,

Mitchell

the "go" tool can do it, if you set the right env vars.

gb (http://code.google.com/p/go-gb) can do it, and also generate makefiles for you (gb --makefiles).

Anywhere I can find documentation on these env vars?

Thanks, I'll take a look at this as well.

I strongly recommend gb, it just works.

If you decided to use makefiles, the DEPS= stanza may be of some use.

Cheers

In a terminal, run "go help gopath". This is the best documentation I have found regarding that env var. Unfortunately it doesn't show up in the godoc - you have to get it from the terminal (someone please correct me if I'm wrong).

It's not in the cmd/go documentation, but it's still visible under src/cmd/go/help.go if you want to hunt for it :)

FWIW I've been keeping a simple project on Github up-to-date with the
latest changes to the build tools. I've just converted it over to
using the 'go' tool and it was fairly easy to set up and get working.
The project consists of two commands (buffer and hello), one of which
relies on another package in the project. Perhaps it will give you an
idea of how you might set things up.
