CLSQL uses ASDF to compile and load its components. ASDF is included in the CCLAN collection.
CLSQL uses UFFI as a Foreign Function Interface (FFI) to support multiple ANSI Common Lisp implementations.
You can download UFFI from its FTP site. There are zip files for Microsoft Windows systems and gzipped tar files for other systems.
The implementations that support CLSQL is governed by the supported implementations of UFFI. The following implementations are supported:
AllegroCL v6.1 on Redhat Linux 7.2, FreeBSD 4.5, and Microsoft Windows XP.
Lispworks v4.2 on Redhat Linux 7.2 and Microsoft Windows XP.
CMUCL 18d-pre on Redhat Linux 7.2, FreeBSD 4.5, and Solaris 2.8.
