This is a small Wiki page about the golang package on Maemo. The package contains the standalone go compiler and libraries targeting armv6.
[edit] Creating a Hello world application using the go programming language
Creating a Hello world application using the go language on the N900. The go compiler and libraries for Maemo are packaged in a package called golang
that can be installed from the fremantle/free repository. The package puts all its content in a directory called /opt/go
to follow Maemo packaging policies.
Once the package is installed we need to set a few environments variables to make the go compiler happy.
Those are:
export GOROOT=/opt/go export GOOS=linux export GOARCH=arm export GOBIN=/opt/go/bin export GOPKG=/opt/go/pkg PATH=$PATH:$GOBIN
The packager provides a script to to this that can be sourced
~ $ . /opt/go/bin/go_profile
Now off to create Hello world. We will create a directory in the users home directory create a small go hello world file, compile, link and run it.
Creating the directory using mkdir
mkdir hello_go
Go into that directory and fire up an editor
cd hello_go vi hello.go
Paste the following
package main import "fmt" func main() { fmt.Printf("Hello, Maemo\n") }
exit vi and compile hello.go
~/hello_go $ 5g hello.go
Link it against the go libs (the output is a staticaly linked binary)
~/hello_go $ 5l hello.5
and now run it
~/hello_go $ ./5.out Hello, Maemo
If all went well you just ran your first go code on Maemo!
