AOT compiling projects

Given a jank Leiningen project, you can ahead of time (AOT) compile all of your code and dependencies to an executable using this command.

lein compile

As with GCC, Clang, etc, the default output name is a.out. When you invoke your executable, your -main function will be called.

Note

There is not yet a way to change the output name using Leiningen, but this will be implemented.

Building for release

By default, lein compile will build you a debug executable with fewer optimizations enabled. To get a release executable, you can enable the release profile.

lein with-profile release compile

Distributing your executables

Currently, AOT compiled executables still depend on jank, Clang, and LLVM. This makes distribution more complicated, especially since the Clang/LLVM version jank requires is bleeding edge. We are working on ways to both better package these together as well as to provide options for building executables which are standalone.
