@cindex ASDF-binary-locations
Each Common Lisp implementation has its own format for
compiled files (fasls for short). If you use multiple
implementations (or multiple versions of the same
implementation), you'll soon find your source directories
littered with various `DFSL`s, `FASL`s, `CFSL`s and so on.
Worse yet, some implementations use the same file extension
or change formats from version to version which means that
you'll have to recompile binaries as you switch from one
implementation to the next.
As of version 1.365, ASDF includes @emph{ASDF-binary-locations} to
mitigate the problem.
@section Default locations
@vindex *place-binaries-in-implementation-specific-directories*
@vindex *centralize-lisp-binaries*
@vindex *default-toplevel-directory*
@vindex *include-per-user-information*
@vindex *map-all-source-files*
@vindex *source-to-target-mappings*
@findex output-files-for-system-and-operation
The default binary location for each Lisp implementation is a
subdirectory of each source directory. To account for different Lisps,
Operating Systems, Implementation versions, and so on, ASDF borrows code
from SLIME to create reasonable custom directory names. Here are
some examples:
@itemize
@item SBCL, version 1.0 on Mac OS X for intel: @code{sbcl-1.0-darwin-x86}
@item Franz Allegro, version 8.0, ANSI Common Lisp: @code{allegro-8.0a-macosx-x86}
@item Franz Allegro, version 8.1, Modern (case sensitive) Common Lisp: @code{allegro-8.1m-macosx-x86}
@end itemize
If you want to keep compiled files out of the source tree entirely, use
@code{*centralize-lisp-binaries*} to put compiled files into
sub-directories of a single central location (see below).
Here is a summary of the variables that control ASDF's source-to-binary mappings:
@itemize
@item @code{*place-binaries-in-implementation-specific-directories*}:
If false, then ASDF will place binaries in the same directory as the
source. If true, then ASDF will move the binaries using the rest of
the configuration. Defaults to @code{nil}.
@item @code{*centralize-lisp-binaries*}: If true, compiled lisp files
without an explicit mapping (see @code{*source-to-target-mappings*})
will be placed in subdirectories of
@code{*default-toplevel-directory*}. If false, then compiled lisp
files without an explicit mapping will be placed in subdirectories
of their sources. Defaults to @code{nil}.
@item @code{*default-toplevel-directory*}. If
@code{*centralize-lisp-binaries*} is true, then compiled lisp files
without an explicit mapping (see @code{*source-to-target-mappings*})
will be placed in subdirectories of
@code{*default-toplevel-directory*}. Defaults to a sub-directory
named `.fasls` in the current user's home directory.
@item @code{*include-per-user-information*}. specifies whether or not
to include user information in the directory. Only used when
@code{*centralize-lisp-binaries*} is true. Defaults to @code{nil}.
@item @code{*map-all-source-files*}. If true, then all source files
will be mapped by ASDF. If @code{nil}, then only Common Lisp Source
Files (i.e., instances of cl-source-file or its subclasses) will
be. Defaults to @code{nil}.
@item @code{*source-to-target-mappings*}. This specifies mappings
from source to target. If the target is nil, then it
means to *not* map the source to anything. I.e., to leave
it as is. This has the effect of turning off
ASDF-Binary-Locations for the given source directory. The
default depends on the Lisp implementation.
@end itemize
These variables are used by
@code{output-files-for-system-and-operation} to determine where to
place a source file's binary. You can further customize asdf-binary-locations
by writing additional methods on the generic function
@code{output-files-for-system-and-operation}.
@c See the [manual][binary-locations] for more details.
@subsection Notes and Issues
SBCL ships with several included ASDF libraries which used to confuse
ABL because it would try to recompile the FASLs and then run into
directory permission problems. ASDF knows about these and uses a mapping
like @file{/usr/local/lib/sbcl} to @code{nil} so that the FASLs are not
relocated.
