- By default, files are installed into this structure. It matches the
- World According to Stallman, aka the GNU filesystem standard.
-
- A "feature" of this standard is to scatter files around the file system
- depending on their purpose. This map is my attempt to document where
- everything ends up and why.
-
- The exact locations depend on arguments given to configure when compiling.
- Type './configure --help' for a summary of available options. See also
- comments after the map.
-
- Some of the directories in this tree are empty. They are included here
- because they are defined in the GNU FSS.

- The following C preprocessor symbols are defined, along with their
- default values:
-
- LIBEXECDIR="/usr/local/libexec/siag"
- DATADIR="/usr/local/share/siag"
- DOCDIR="/usr/local/doc/siag"
-
- The following C and SIOD string variables are set, along with their
- default values:
-
- libexecdir=LIBEXECDIR
- datadir=DATADIR
- docdir=DOCDIR
-
- The libexecdir variable is used to find plugins. The datadir is used to
- find Scheme libraries. The docdir is used to find online documentation.
- The docdir is a de facto standard extension to the GNU standard.
-
- Important change: nothing is installed into the /usr/local/lib
- directory. Previous versions installed plugins and Scheme files there.
-
- As usual, things are meant to be installed by typing "make install" and
- not moved around manually afterwards. Putting files where Siag can't find
- them will inevitably lead to loss of functionality and possibly loss of
- data. However, it is possible to move the files if the environment
- variables SIAGHOME and SIAGDOCS are used to tell Siag their new
- whereabouts. If the variables are set, the following changes are
- made to the directory structure:
-
- $SIAGHOME
- |-/siod SIOD runtime library
- |-/common Dictionaries, common Scheme libraries
- |-/xcommon Scheme libraries for X support
- |-/plugins Plugins, scheme libraries for plugins
- |-/siag Scheme for all versions of Siag
- |-/xsiag Scheme for Xt version of Siag
- |-/pw you get the picture...
- |-/xpw
- |-/egon
- `-/xegon
-
- $SIAGDOCS
- |-/siod SIOD docs
- |-/common Common docs
- |-/xcommon Common X docs
- |-/siag Siag docs
- | `-/examples Siag examples
- |-/xsiag Xt Siag docs
- |-/pw PW docs
- | `-/examples PW examples
- |-/xpw Xt PW docs
- |-/egon Egon docs
- | `-/examples Egon examples
- `-/xegon Xt Egon docs
-
- Setting the variables changes these C and SIOD variables in the
- following way:
-
- libexecdir=$SIAGHOME
- datadir=$SIAGHOME
- docdir=$SIAGDOCS
-
- Simply put: $SIAGHOME contains the merged contents of
- /usr/local/libexec/siag and /usr/local/share/siag.
- $SIAGDOCS contains the contents of /usr/local/docs/siag.
-
- This exercise is not recommended. It is only meant for installing
- pre-compiled binaries on systems where you are not root and recompiling
- is not an option. Better solutions include:
-
- - become root
- - get a compiler
- - get a new system
- - grow tomatoes
