In addition, if you use an unusual directory layout you can give

options like `--bindir=DIR' to specify different values for particular
|

kinds of files. Run `configure --help' for a list of the directories
|

'CONFIG_SITE' environment variable to the location of the site script.

A warning: not all 'configure' scripts look for a site script.

Defining Variables
|

==================
|

|

Variables not defined in a site shell script can be set in the
|

environment passed to `configure'. However, some packages may run
|
||||
environment passed to 'configure'. However, some packages may run
|
||||
configure again during the build, and the customized values of these
|
||||
variables may be lost. In order to avoid this problem, you should set
|
||||
them in the `configure' command line, using `VAR=value'. For example:
|
||||
them in the 'configure' command line, using 'VAR=value'. For example:
|
||||
|
||||
./configure CC=/usr/local2/bin/gcc
|
||||

causes the specified 'gcc' to be used as the C compiler (unless it is

overridden in the site shell script).
|
||||
|
||||
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
||||
an Autoconf limitation. Until the limitation is lifted, you can use
|

this workaround:

`--cache-file=FILE'

Enable the cache: use and save the results of the tests in FILE,

traditionally `config.cache'. FILE defaults to `/dev/null' to
