Build examples

Building your software with Flox is as simple as providing a short script to run the build command and copy the artifact to a Flox-provided directory. Below are examples for various ecosystems.

Autotools

[build.myproject]
command = '''
  ./configure --prefix=$out
  make
  make install
'''

Go

[build.myproject]
command = '''
  GOBIN=$out/bin go install
'''

Rust

[build.myproject]
command = '''
  cargo build --release
  mkdir -p $out/bin
  cp target/release/myproject $out/bin/myproject
'''

Python

For Python projects a build looks like installing the project to the $out directory.

[build.myproject]
command = '''
  pip install --target=$out .
'''

Note the trailing . to indicate that you're installing the package in the current directory. If you're working in a repository with multiple packages in subdirectories, you would replace . with the path to the package sources.

This works for projects using pyproject.toml as well (including Poetry) as long as the [build-system] section of pyproject.toml is filled out.

Node.js

Node.js applications should have their node_modules directory placed under the $out/lib directory.

[build.myproject]
command = '''
  npm install --production --prefix=$out/lib
'''
