# Minimal Python source build on Linux

This directory shows how to bootstrap a local build from source on Linux with
an eye toward maximum portability across different Linux distributions. This
may help for contributors debugging build issues caused by their local
environments.

## Fedora 31

First, build the Docker image using:
```
docker build -t arrow_fedora_minimal -f Dockerfile.fedora .
```

Then build PyArrow with conda or pip/virtualenv, respectively:
```
# With pip/virtualenv
docker run --rm -t -i -v $PWD:/io arrow_fedora_minimal /io/build_venv.sh

# With conda
docker run --rm -t -i -v $PWD:/io arrow_fedora_minimal /io/build_conda.sh
```

## Ubuntu 18.04

First, build the Docker image using:
```
docker build -t arrow_ubuntu_minimal -f Dockerfile.ubuntu .
```

Then build PyArrow with conda or pip/virtualenv, respectively:
```
# With pip/virtualenv
docker run --rm -t -i -v $PWD:/io arrow_ubuntu_minimal /io/build_venv.sh

# With conda
docker run --rm -t -i -v $PWD:/io arrow_ubuntu_minimal /io/build_conda.sh
```

## Building on Fedora - Podman and SELinux

In addition to using Podman instead of Docker, you need to specify `:Z`
for SELinux relabelling when binding a volume.

First, build the image using:
```
podman build -t arrow_fedora_minimal -f Dockerfile.fedora
```

Then build PyArrow with pip/virtualenv:
```
# With pip/virtualenv
podman run --rm -i -v $PWD:/io:Z -t arrow_fedora_minimal /io/build_venv.sh
```
