The GNAT Community Edition is available directly from the official Arch repositories.

sudo pacman -Syu          # Update the system first
sudo pacman -S gnat       # Installs the compiler, runtime, and standard library

After the install you should have:

| Tool | Path | Purpose | |------|------|---------| | `gnatmake` | `/usr/bin/gnatmake` | Build Ada programs | | `gnat` | `/usr/bin/gnat` | Compiler driver | | `gnatbind` | `/usr/bin/gnatbind` | Binder | | `gnatlink` | `/usr/bin/gnatlink` | Linker | | `gnatgcc` | `/usr/bin/gnatgcc` | GCC wrapper for Ada |

Create a simple “Hello, Ada!” program:

cat <<'EOF' > hello.adb
with Ada.Text_IO; use Ada.Text_IO;

procedure Hello is
begin
   Put_Line ("Hello, Ada!");
end Hello;
EOF

Compile and run:

gnatmake hello.adb
./hello

You should see:

Hello, Ada!

If you want the latest bleeding‑edge version or a specific build, you can use an AUR helper:

# Using yay (replace with your preferred AUR helper)
yay -S gnat-community

The AUR package usually builds the same binaries as the official repo but may include newer patches.
