DE.SETF.AMQP: How to Build It

In principle, de.setf.amqp is built with asdf.


  1. Obtain the required libraries (see amqp.asd). The sources are reflected in the respective system names:
  2. Obtain the de.setf.amqp source and that for the de.setf.utility library
  3. Obtain and load asdf, add the hierarchical names utility.
  4. Place the libraries in a source tree to mirror their global identity as reflected in the required system names, and add the root of this tree to the asdf registry. If the central registry entry specifies a logical host with binary mapping, the hierarchical naming mechanism should suffice to map binaries the specified location. The bordeaux-threads -> alexandria reference is unqualified, and as such, requires additional registration.
  5. Compile and load as: (asdf:operate 'asdf:load-op :de.setf.amqp._version_)

The example initialization file was used for CCL and SBCL. Contact me should any questions arise.



ASDF requires version 1.622 in order to construct correct component pathnames where the system has a logical root pathname.

On OS X, I have observed symbolic registry finder links to fail to work from ccl and sbcl. An ln -s in the terminal is required.

hierarchical system names

There are, to date, 498 .asd files in my combined production and development source trees. Each system is identified by provenance and found in the file system at a location to be inferred from its identifier. Thus, given the development source tree root


the pathname for the de.setf.amqp system definition is


This convention is supported by the asdf hierarchical names extension. It adds a system search method which parses the system identifier and uses its elements to prospectively augment locations from the *central-registry* with directory paths. Versions are supported by probing with a wild suffix added to the name of the final directory, and by electing the most recently modified system file if several versions are found. A nickname is added to each loaded system to augment an unqualified name with a qualified one.

Where the dependencies in a system definition use unqualified cross-references, this fails. Thus alexandria requires a registry addition to permit the cross-reference from usocket.

logical pathnames

The source and binary file names are expressed as logical pathnames in order that they can be remapped to new locations for delivered images.

  • LIBRARY : locates the root of the source tree
  • AMPQ : locates the root of the specific AMQP source

If asdf output location mapping is disabled, the binary files are stored in LIBRARY:bin; and AMPQ:bin;. Once can change this, but changing the logical pathname transaltions. In order to update the host translations for a relocaed image

(setf (logical-pathname-translations "AMQP") nil
      (logical-pathname-translations "LIBRARY") nil)
(asdf:find-system :de.setf.utility)
(asdf:find-system :de.setf.amqp)

Macintosh Common Lisp

If the asdf version includes mandatory output translations, either disable that or otherwise ensure that it does not choke on the default binding for user-homedir-pathname.
