# libmach Build the `libmach` dynamic library by running `make` (or running `zig build` in the parent directory). The resulting binary should be located in `libmach/build/`. Test the functionality of `libmach` using `make test_c` and `make test_lisp`. These commands use C and Lisp to call into `libmach`, and both should show a blank window for 5 seconds. If you resize the window, it should print the new dimensions to the standard output. Note: `make test_lisp` requires a relatively recent version of Steel Bank Common Lisp (`sbcl`) to be installed, plus Quicklisp. You can find the Zig source code for `libmach` in `src/platform/libmach.zig`.
