# Installation

## Bioconda (binary)

The recommended way to install NGLess is through [bioconda](http://bioconda.github.io):

conda install -c bioconda ngless

This will install the most recent released version

### Docker

Alternatively, a docker container with NGLess is available at [docker hub](https://hub.docker.com/r/nglesstoolkit/ngless):

docker run -v $PWD:/workdir -w /workdir -it nglesstoolkit/ngless:1.4.1 ngless –version

Adapt the mount flags (-v) as needed. You can use the latest tag to get a more up to date version as well.

## Linux (binary)

You can download a [statically linked version of NGless 1.4.1](https://github.com/ngless-toolkit/ngless/releases/download/v1.4.1/NGLess-v1.4.1-Linux-static-full).

This should work across a wide range of Linux versions (please [report](https://github.com/ngless-toolkit/ngless/issues) any issues you encounter):

curl -L -O https://github.com/ngless-toolkit/ngless/releases/download/v1.4.1/NGLess-v1.4.1-Linux-static-full chmod +x NGLess-v1.4.1-Linux-static-full ./NGLess-v1.4.1-Linux-static-full

This downloaded file bundles bwa, samtools and megahit (also statically linked).

## From source

[Stack](https://docs.haskellstack.org/en/stable/README.html) is the simplest way to install the necessary requirements.

The following sequence of commands should download and build the software

git clone https://github.com/ngless-toolkit/ngless cd ngless make

The first time you run this, it will take a while as it will download all dependencies. After this ngless is ready to use and subsequent builds will be much faster.

## Make targets

The following are targets in the Makefile.

• make: compiles NGLess and haskell dependencies
• clean: remove local generated files by compilation
• check: run tests
• bench: run benchmarks
