Unable to open *.el.gz files

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. Please describe as succinctly as possible: - What happened. - What you thought should have happened. - Precisely what you were doing at the time. Please also include any C or lisp back-traces that you may have. ================================================================ Dear Bug Team! I am unable to open any *.el.gz in load-path using find-library. It works fine when /usr/lib/xemacs-21.4.9/lisp directory is owned by the person who installed it (in this case myself). In order to avoid any changes by mistake to the files under /usr/lib/xemacs-21.4.9/lisp, I changed the ownership to root. After that I am unable to open any library which is gzipped. I get the following stack trace when I try to do so: Signaling: (buffer-read-only #<killed buffer>) signal(buffer-read-only (#<killed buffer>)) byte-code("..." [buf data kill-buffer signal] 3) find-file-noselect("/usr/lib/xemacs-21.4.9/lisp/font-lock.el.gz") find-file("/usr/lib/xemacs-21.4.9/lisp/font-lock.el.gz" nil) #<compiled-function (library &optional codesys display-function) "...(39)" [codesys load-path display-function path library "" locate-file ":.el:.el.gz:.el.Z:.elc" fboundp find-file error "(find-library): Cannot locate library `%s'"] 5 928139 (list (read-library-name "Find library: ") (if current-prefix-arg ...))>("font-lock" nil) call-interactively(find-library) Since the files have world read permissions, why can't emacs read the *.el.gz files and decode it in memory without relying on the permissions ? If I am totally offtarget and I should have built my XEmacs with zlib support, please tell me how to do that. -kitty. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux samba 2.4.18-11smp #1 SMP Thu Aug 15 06:41:59 EDT 2002 i686 unknown ./configure '--prefix=/usr' '--cflags=-Os -march=pentium3' '--pdump' '--with-sound=none' '--mail-locking=lockf' '--error-checking=none' '--infodir=/usr/share/info' '--mandir=/usr/share/man' '--with-file-coding' XEmacs 21.4.9 "Informed Management" configured for `i686-pc-linux'.
