# Setup your Keyman build environment on Ubuntu
## Target Projects
On Linux, you can build the following projects:
* [Keyman for Linux](#keyman-for-linux)
* [Keyman Core](#keyman-core) (Linux only) (aka core)
<!-- TODO: document how to build for Android, Web, Core-Wasm and Common/Web on Linux. See TC build agent for details. -->
* Keyman for Android
* Keyman Core (wasm targets)
* Common/Web
* KeymanWeb
The following projects **cannot** be built on Linux:
* Keyman for Windows
* Keyman Developer
* Keyman for macOS
* Keyman for iOS
## System Requirements
* Minimum Ubuntu version: Ubuntu 18.04
Other Linux distributions will also work if appropriate dependencies are installed.
## Repository Paths
Recommended filesystem layout:
```text
$HOME/keyman/
keyman/ this repository (https://github.com/keymanapp/keyman)
keyboards/ https://github.com/keymanapp/keyboards
sites/
keyman.com/ https://github.com/keymanapp/keyman.com
...
```
## Prerequisites
The current list of dependencies can be found in the `Build-Depends` section of `linux/debian/control`.
They are most easily installed with the `mk-build-deps` tool:
```bash
sudo apt update
sudo apt install devscripts equivs
sudo mk-build-deps --install linux/debian/control
```
## Keyman for Linux
All dependencies are already installed if you followed the instructions under [Prerequisites](#Prerequisites).
Building:
* [Building Keyman for Linux](../../linux/README.md)
## Keyman Core
All dependencies are already installed if you followed the instructions under [Prerequisites](#Prerequisites).
Building:
* [Building Keyman Core](../../core/doc/BUILDING.md)
## Docker Builder
The Docker builder allows you to perform a linux build from anywhere Docker is supported.
To build the docker image:
```shell
cd ../../linux
docker pull ubuntu:latest
docker build . -t keymanapp/keyman-linux-builder:latest
```
Once the image is built, it may be used to build parts of Keyman.
- core
```shell
# build 'core' in docker
cd ../core
# keep linux build artifacts separate
mkdir -p build/linux
docker run -it --rm -v $(pwd)/..:/home/build -v $(pwd)/build/linux:/home/build/core/build keyman-linux-builder:latest bash -c 'cd core; bash build.sh -d'
```
- linux
```shell
# build 'linux' installation in docker
# runs as root!
# note: run 'git clean -fdx linux' afterwards to cleanup
cd keymanapp/keyman
docker run -it --rm -v $(pwd):/home/build/src/keyman -u root -w /home/build/src/keyman keymanapp/keyman-linux-builder:latest bash -c "cd linux && make reconf && make fullbuild && make install"
```
