Please add instructions on how to install dependencies

[xrmx]

For go newbies (like myself) it is quite daunting how go handle package dependencies. What I've tried seems not to be sufficient:

export GOPATH=$(pwd)
go get github.com/tools/godep
./bin/godep get ./...

I got some issues like having to download dependencies with go get because godep did not find them:

src/github.com/onsi/gomega/ghttp/handlers.go:12:2: cannot find package "github.com/golang/protobuf/proto" in any of:
    /usr/lib/go/src/github.com/golang/protobuf/proto (from $GOROOT)
    /home/rm/src/arduino-create-agent/src/github.com/golang/protobuf/proto (from $GOPATH)

Looks like there are some issues on Godeps due to some broken libs. We are considering to add all the deps inside the git repo to have it always consistent.

@mastrolinux if it's a godeps issue then nothing to fix here. Is that the corrrect way to install dependencies, if so i can do a pull request.

So after getting somehow the dependencies installed, trying ./compile_webidebridge.sh. It fails in createZipEmbeddableFileArduino because i am missing some stuff in arduino/.

In createZipEmbeddableFileArduino
cp: cannot stat 'arduino/hardware': No such file or directory
cp: cannot stat 'arduino/tools_linux_arm': No such file or directory
cp: cannot stat 'arduino/boards.json': No such file or directory
cp: cannot stat 'fakecerts/*.pem': No such file or directory
cp: cannot stat 'fakecerts/*.cer': No such file or directory
mv: cannot stat 'arduino/arduino/tools*': No such file or directory

The workaround is easy (see below), would it make sense to add a switch to avoid the zip creation or the missing files are really needed?

 extractVersionFromMain

BTW that script should probably be a Makefile.

[facchinm]

I agree that the script needs some love, createZipEmbeddableFileArduino function is a legacy of the pre-installer version and the whole script could be simplified.
I wouldn't turn it into a Makefile because its target is simply cross compiling, since the native compilation only needs

export GOPATH=$PWD
go get
go build

to generate an arduino-create-agent binary on any platform
