leo build

To compile your program into Aleo instructions and verify that it builds properly, run:

leo build

On invoking the build command, Leo automatically creates a build/⁠ and output/⁠ folder in the project directory. The compiled .aleo file is contained in the build directory. The output directory is used to stored intermediate artifacts from compilation.

console output:

  Leo     2 statements before dead code elimination.
  Leo     2 statements after dead code elimination.
  Leo     The program checksum is: '[...]'.
  Leo ✅ Compiled '{PROGRAM_NAME}.aleo' into Aleo instructions.
