This container is available from Docker Hub.
docker pull droboports/compiler
docker build --tag="droboports/compiler" https://github.com/droboports/docker-cross-compiler.git
docker run --rm -t -i droboports/compiler
From the container prompt:
cd ~/build
git clone https://github.com/droboports/busybox.git
cd busybox
./build.sh
ls -la *.tgz
From the container prompt:
cd ~/build
git clone https://github.com/droboports/samba.git
cd samba

From the container prompt:
cd ~/build
export GOPATH=/mnt/DroboFS/Shares/DroboApps/hello-world
cat > hello-world.go << EOF
package main
import "fmt"
func main() {
fmt.Println("hello world")
}
EOF
go build -o hello-world hello-world.go
This is the resulting hello-world:
$ file hello-world
hello-world: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, not stripped
This container provides a special build command to build projects in Git repositories.
The build command has two forms: build PROJECT_NAME and build GIT_URL.
The build PROJECT_NAME form is a shortcut to build a project from the DroboPorts GitHub organization (https://github.com/droboports), with the PROJECT_NAME being the last component of the GitHub URL. For example, the PROJECT_NAME for the https://github.com/droboports/busybox project would be simply busybox.
The build GIT_URL form allows any arbitrary Git repo to be built. For GitHub repos, GIT_URL would be the clone URL (e.g., https://github.com/droboports/busybox.git). The URL can optionally include a fragment ID to specify a branch or tag name. For example, to build the v0.0.1 tag in your https://github.com/username/project.git repo, the GIT_URL would be https://github.com/username/project.git#v0.0.1. Without a branch or tag name specified, the default Git branch will be used.
(Note that the building a specific branch or tag only works with the build GIT_URL form.)
To use the build command, first create a folder to host the resulting packages:
mkdir -p ~/dist
chmod a+rw ~/dist
Then start the container using the special build syntax:
docker run --rm --volume ~/dist:/dist droboports/compiler build PROJECT_NAME
Once the build is done, ~/dist will contain PROJECT_NAME.tgz.
