# Build xds-agent from scratch ## Dependencies Install [Go](https://golang.org/doc/install), [npm](https://www.npmjs.com/), [nodejs](https://nodejs.org/en/) and some other tools. Refer to [Prerequisites chapter](../1_Prerequisites.html) for more details. ## Building Clone sources under `$ROOTDIR/src/gerrit.automotivelinux.org/gerrit/src/xds/xds-agent` in order respect directory hierarchy that match Go package import logic (see [How to Write Go Code](https://golang.org/doc/code.html) for more details). Then use delivered Makefile : ```bash # Declare ROOTDIR, can be any location (for example xds-build) ROOTDIR=$HOME/xds-build # Create directory hierarchy that match Go package import logic mkdir -p $ROOTDIR/src/gerrit.automotivelinux.org/gerrit/src/xds cd $ROOTDIR/src/gerrit.automotivelinux.org/gerrit/src/xds # Clone sources git clone https://gerrit.automotivelinux.org/gerrit/src/xds/xds-agent # or git clone ssh://YOUR_USERNAME@gerrit.automotivelinux.org:29418/src/xds/xds-agent # Build xds-agent # (note that GOPATH will correctly be set by Makefile) cd xds-agent make all ``` Generate xds-agent packages / tarballs for Linux, MacOS, Windows ```bash make package-all ``` And to install `xds-agent` (by default in `/opt/AGL/xds/agent`): ```bash make install ``` **Warning:** Makefile install rule and default values in configuration file are set to fit the docker setup. So you may need to adapt some settings when you want to install xds-agent natively. **Note:** Used `DESTDIR` to specify another install directory ```bash make install DESTDIR=$HOME/opt/xds-agent ``` ### Cross build For example on a Linux machine to cross-build for Windows, just follow these steps. The first time you need to install all the windows-amd64 standard packages on your system with ```bash # List all supported OS / ARCH go tool dist list # Install all standard packages for another OS/ARCH (eg. windows amd64) GOOS=windows GOARCH=amd64 go install -v -a std ``` Then compile and package xds-agent using provided makefile ```bash export GOOS=windows export GOARCH=amd64 make all make package ```
