Installation

Linux/Unix

This is the bare minimum to get the server running. To set up a full Common Lisp development environment, see here

• Install sbcl and lmdb from apt or using your favorite method.
  e.g. sudo apt install sbcl liblmdb0

• Install quicklisp
  curl -O https://beta.quicklisp.org/quicklisp.lisp
sbcl --load quicklisp.lisp --eval '(quicklisp-quickstart:install)' --eval '(ql:add-to-init-file)' --eval '(exit)'

• Clone required git repositories to the quicklisp local-projects directory. (You can also use symlinks if you want to put them elsewhere.)
  cd ~/quicklisp/local-projects
git clone https://github.com/kronusaturn/liblmdb.git
git clone https://github.com/kronusaturn/lmdb.git
git clone https://github.com/kronusaturn/plump.git
git clone https://github.com/kronusaturn/lw2-viewer.git

• Start the server
  cd ~/quicklisp/local-projects/lw2-viewer
sbcl --eval '(ql:quickload :lw2-viewer)' --eval '(hunchentoot:start (make-instance (quote hunchentoot:easy-acceptor) :port 4242 :document-root "./www/"))'

• Open http://localhost:4242 in your browser

Mac

Similar to above, but:

• sbcl and lmdb are available from MacPorts.

• Make sure to run system updates, using an outdated OS version can cause installation errors.

• As Mac OS does not support sparse files, the system will create an empty 16 GB file on startup. If you want to reduce disk space usage, before starting the server, copy config-example.lisp to config.lisp and change the line (defparameter *lmdb-mapsize* (expt 2 34)) to, for example, (defparameter *lmdb-mapsize* (expt 2 28))

• You will need to set the DYLD_LIBRARY_PATH environment variable to the location where liblmdb.dylib is installed, for example export DYLD_LIBRARY_PATH=/opt/local/lib/
