This crate provides Rust bindings to the quilc C library.

SBCL must be installed from source to make sure you have the libsbcl shared library available.

1. Install sbcl from a package manager for bootstrapping purposes.
2. Clone the repository: git clone --branch sbcl-2.2.0 git://git.code.sf.net/p/sbcl/sbcl

• Tag sbcl-2.2.0 is known to work. These instructions have not been tested against a newer version.

1. Inside the cloned repo: sh make.sh && sh make-shared-library.sh
2. Uninstall the package manager version of sbcl.
3. Run sh install.sh to install the compiled sbcl
4. Copy src/runtime/libsbcl.so to /usr/local/lib/libsbcl.so

1. Follow the official instructions to install Quicklisp.

Quicklisp has a local projects mechanism which we'll be using to build quilc with it's dependencies. By default, this directory is $HOME/quicklisp/local-projects. If you want to use something different, you need to make sure $HOME/.sbclrc contains the following (replace $LISP_WORKSPACE with the actual value):

;;; The following lines added by ql:add-to-init-file:
#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
                                       (user-homedir-pathname))))
  (when (probe-file quicklisp-init)
    (load quicklisp-init)))

#+quicklisp
(push "$LISP_WORKSPACE" ql:*local-project-directories*)

From here on, we'll refer to the local project directory you've chosen to use, whether it's the default or not, as $LISP_WORKSPACE.

Important: The above sbcl folder must not be in the workspace folder -- it will cause issues.

1. Clone the following repos into $LISP_WORKSPACE
   • https://github.com/quil-lang/qvm
   • https://github.com/quil-lang/magicl
   • https://github.com/quil-lang/quilc
   • https://github.com/quil-lang/sbcl-librarian

Note: The build commands in quilc assume you are running on MacOS and will error on other systems.

Run the following from $LISP_WORKSPACE:

make -C quilc
make -C quilc/lib

Optionally, run tests:

# Optional -- run tests
make -C quilc/tests/c  # Builds executables to manually run
cp quilc/lib/libquilc.core quilc/lib/tests/c/
# MacOS
cp quilc/lib/libquilc.dylib quilc/lib/tests/c/
# *nix
cp quilc/lib/libquilc.so quilc/lib/tests/c/
echo "H 0" | quilc/lib/tests/c/compile-quil

By default, this library assumes quilc is in the default Quicklisp local projects directory ($HOME/quicklisp/local-projects). If you defined a non-default local projects directory for quilc, you need to set $QUILC_LIBRARY_PATH to the folder where you built the quilc library (the folder containing libquilc.dylib). For example,

export QUILC_LIBRARY_PATH=$LISP_WORKSPACE/quilc/lib

Then, from the root of this repository:

cp "$LISP_WORKSPACE/quilc/lib/libquilc.dylib" .
cp "$LISP_WORKSPACE/quilc/lib/libquilc.core" .
cargo test
