If you have a small number of duplicated +libraries, it is probably one or more packages available both in the +XEmacs distribution and in third-party distributions. If you prefer the +third-party version, use ＠kbd{M-x list-packages} to get the package +management UI, and uninstall the particular packages. Removal of third +party packages must be done manually, if you wish to keep the version +distributed by XEmacs. + +When you have many duplicate packages, a common cause is that XEmacs +finds ＠emph{package root directories} that are duplicates of each other. +This can occur in some automounter configurations, or when the roots +share some subtrees via symlinks. In this case, you will get a warning +for ＠emph{all} of the packages you have installed. Although this is +basically a site configuration problem, please report these cases. +XEmacs is already aware of many automounter artifacts, and automatically +adjusts for them. Code is being added to try to detect symlinks. We +may not be able to handle every case, but we'd like to know about them, +and where possible incorporate workarounds. + +Package root directories are specified at configuration time via the +＠code{--prefix}, ＠code{--exec-prefix}, and the ＠samp{--with-*-packages} +options; at runtime relative to the XEmacs binary (＠file{../share} and +＠file{..} (for run-in-place)); and at runtime via the +＠samp{EMACS*PACKAGES} environment variables. Unless you have special +needs, it is best to install XEmacs and the packages (configuring with +＠code{--with-prefix=$prefix} for XEmacs and by untarring the SUMOs in +＠file{＠code{$prefix}/share/xemacs/}. + +Note that older versions of XEmacs (21.1, 21.4, and early releases of +21.5) by default expect the packages to be installed under +＠file{＠code{$prefix}/lib} rather than ＠file{＠code{$prefix}/share}. See +the documentation for ＠file{configure} for how to point XEmacs at +＠file{＠code{$prefix}/share/xemacs/} if that is preferred, or older +XEmacsen need to share packages with recent versions. + ＠node Editing, Display, Installation, Top ＠unnumbered 3 Editing Functions _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-patches
