Build Hangar

Hangar is written in Golang.

You can follow the below instructions to build hangar executable binary.

Building in a container

1. Requirements:

   • Ensure docker, curl, make installed.
   • Hangar only supports Linux & Unix systems.

2. Clone the source code.

   git clone https://github.com/hangar.git && cd hangar

3. Build hangar in container by executing make commands:

   # Get help information
   make help
   
   # Build hangar in container
   make build

4. The built binary file is available in bin directory.

Building without a container

1. Install following build dependencies:

   • Golang >= 1.22.2

   # Arch Linux
   sudo pacman -S base-devel gpgme device-mapper btrfs-progs
   
   # Ubuntu/Debian
   sudo apt install libgpgme-dev libassuan-dev libbtrfs-dev libdevmapper-dev pkg-config gcc
   
   # macOS
   brew install gpgme
   
   # openSUSE
   sudo zypper install libgpgme-devel device-mapper-devel libbtrfs-devel glib2-devel
   
   # Fedora
   sudo dnf install gpgme-devel libassuan-devel btrfs-progs-devel device-mapper-devel

2. Clone the source code.

   git clone https://github.com/hangar.git && cd hangar

3. Build hangar by execute build scripts manually:

   ./scripts/build.sh

4. The built binary file is available in the bin directory.

Disable CGO

You can add DISABLE_CGO=1 environment variable when building hangar with CGO disabled.

note

Keep in mind that the resulting binary is unsupported and might crash randomly. Only use if you know what you're doing!
