As with all make-based build systems, variables used in the makefiles can be overridden by the user. This section describes variables that developers may find useful to override while installing. The variables are listed alphabetically.
Provide an alternate installation prefix than what was set at configuration time. This is handy if testing the installation process or if no prefix was given at configuration time. Specifying a value for this variable is all that is necessary to change the entire installation path of Juggler.
Define an alternate ABI/ISA combination than the default set by configure. This accepts exactly the same values as the --with-abi argument to the configure script. Results of its use can be seen near the bottom of Makefile.base. If this was used as part of compiling, it must also be used for installing to ensure that everything is installed properly.
Disable ths installation of VRJConfig by setting this variable to 1 when building. This is very handy when VRJConfig is not building properly or is not needed for whatever reason.
Provide a different version of a Perl 5.004 or newer binary than what configure found. Perl is crucial to the installation process because several Perl scripts are used (see the section called “Custom Scripts”). If it necessary to use a different perl binary than the one that configure found, it can be named with this variable. All Perl scripts will use it.
