[xemacs-hg @ 2003-03-01 07:25:26 by ben] build patch Makefile.in.in: Move src deletions to src/Makefile.in.in. dump-paths.el, dumped-lisp.el: Delete. Combine stuff into setup-paths.el. find-paths.el: Removed. Make this file contain generic routines only. Move stuff to compute Emacs roots to setup-paths.el. startup.el: Removed. Move these variables into setup-paths.el. setup-paths.el, startup.el: Removed. Combine all high-level code for computing the paths into setup-paths.el. Create new function startup-find-load-path to encapsulate all logic for computing `load-path'. Eliminate invocation-directory and invocation-name parameters since there is no point (false generality) -- the code references other globals, which cannot be specified. Eliminate some code duplicated between setup-paths.el and startup.el. Clean up the debug-paths code and output load-path in addition. Add logic to paths-emacs-root-p to support separated source and build trees. loadup.el, make-docfile.el, update-elc-2.el, update-elc.el: Rewrite to allow for separated source and build trees, as may occur in MS Windows. NOTE TO BUILD HACKERS: loadup.el, make-docfile.el, update-elc.el and update-elc-2.el made two assumptions that are no longer correct: (1) The source and build trees are in the same place. (2) They can make assumptions about where `.' is. These files now compute the locations of the source and build roots at the top of the file. *ALL* constant file names or path snippets must now be made absolute using expand-file-name and one of these roots. dumped-lisp.el, packages.el: Removed. Remove some unused lists of Lisp files. packages-hardcoded-lisp (empty, in any case) moved to dumped-lisp.el. startup.el: When a compiled init file is out-of-date wrt the uncompiled version, load the uncompiled version and issue a nasty warning. update-elc-2.el: Force touching of auto-autoloads files when REBUILD_AUTOLOADS was set. update-elc.el: Fix code that checks whether dumping is necessary to check against xemacs.dmp, not xemacs.exe, when Unix and pdump. lwlib-Xm.c: Fix compile warning. README, config.inc.samp, xemacs.mak: -- Major reorganization and cleanup. -- Add support for separated build tree and source tree. -- Delete all support for X Windows building, since it's totally bit-rotten and will never be fixed up. Instruct people to use Cygwin if they want such support. make-build-dir: New script to create a skeleton build tree for use with separated build and source tree compilation. m/acorn.h, m/alliant-2800.h, m/alliant.h, m/altos.h, m/amdahl.h, m/arm.h, m/att3b.h, m/aviion.h, m/clipper.h, m/cnvrgnt.h, m/convex.h, m/cydra5.h, m/delta.h, m/delta88k.h, m/dpx2.h, m/elxsi.h, m/ews4800r.h, m/gould.h, m/hp800.h, m/hp9000s300.h, m/i860.h, m/ibmps2-aix.h, m/ibmrs6000.h, m/ibmrt-aix.h, m/ibmrt.h, m/intel386.h, m/iris4d.h, m/iris5d.h, m/iris6d.h, m/irist.h, m/m68k.h, m/masscomp.h, m/mg1.h, m/mips-nec.h, m/mips-siemens.h, m/mips.h, m/nh3000.h, m/nh4000.h, m/ns32000.h, m/plexus.h, m/powerpc.h, m/sequent-ptx.h, m/sequent.h, m/sgi-challenge.h, m/stride.h, m/tad68k.h, m/targon31.h, m/tekxd88.h, m/template.h, m/tower32.h, m/tower32v3.h, m/ustation.h, m/wicat.h, m/xps100.h, data.c, doc.c, editfns.c, emacs.c, lrecord.h, ntheap.c, process-unix.c, sysdep.c, unexec.c: Delete all support for bit-rotten CANNOT_DUMP. Just use pdump. Makefile.in.in: Lots o' cleanup. Use names like LISP, SRC instead of lispdir, srcdir, for consistency with xemacs.mak and the conventions in the rest of the file. Eliminate use of ${...} in favor of $(...), to make it easier to move code between this file and xemacs.mak. Fix dependency handling wrt NEEDTODUMP to eliminate problems some people (e.g. Vin) have been seeing with non-GNU makes. Write a long section about the subtle but oh-so-important differences in dependency processing between nmake, make, and GNU make. Add unicode-encapsulate target, from xemacs.mak. chartab.c, lrecord.h: Fix crash due to attempt to free objects across dump/undump.

/* The purpose of this file is to let the user choose which packages
   to install, and which versions of the package when more than one
   version is provided.  The "trust" level serves as an indication as
   to which version should be the default choice.  At the moment, all
   we do is compare with previously installed packages to skip any
   that are already installed (by setting the action to ACTION_SAME).
   While the "trust" stuff is supported, it's not really implemented
   yet.  We always prefer the "current" option.  In the future, this
   file might have a user dialog added to let the user choose to not
   install packages, or to install packages that aren't installed by
   default. */
