Maybe that installation was made using another installer, or used .gaprc file containing a call to load Grape? Also, 'RequirePackage' is an old name which was already replaced by 'LoadPackage' some time ago. Anyhow, with GAP 4.5 the concept of autloaded packages has been withdrawn. Please see '?The gap.ini and gaprc files' for the description of the current mechanism for the user's customisation. If you don't have the gap.ini file yet, the easies way is to call WriteGapIniFile and then to edit the file which will be created, for example: gap> WriteGapIniFile(); #I File ......some-path/gap.ini successfully written. true Now open the file in the location told by the command above and find there the lines: ## A list of names of packages which should be loaded during startup. For ## backwards compatibility, the default lists most of packages that were ## autoloaded in GAP 4.4 (add or remove packages as you like). # SetUserPreference( "PackagesToLoad", [ "autpgrp", "alnuth", "crisp", # "factint", "fga", "irredsol", "laguna", "polenta", "polycyclic", # "resclasses", "sophus" ] ); Now, if you wish Grape to be loaded automatically each time you start GAP, all you need to do is to uncomment SetUserPreference call and add "grape" there.
