problems

windows版本的emacs

If you want to stick with the Cygwin FTP client, you can work around
this problem by putting this in your `.emacs' file:

 (setq ange-ftp-ftp-program-args '("-i" "-n" "-g" "-v" "--prompt" "")


* Versions of the W3 package released before Emacs 21.1 don't run
under Emacs 21.  This fixed in W3 version 4.0pre.47.

* On AIX, if linking fails because libXbsd isn't found, check if you
are compiling with the system's `cc' and CFLAGS containing `-O5'.  If
so, you have hit a compiler bug.  Please make sure to re-configure
Emacs so that it isn't compiled with `-O5'.

* Compiling on AIX 4.3.x or 4.4 fails.

This could happen if you use /bin/c89 as your compiler, instead of
the default `cc'.  /bin/c89 treats certain warnings, such as benign
redefinitions of macros, as errors, and fails the build.  A solution
is to use the default compiler `cc'.

* Old versions of the PSGML package use the obsolete variables
`before-change-function' and `after-change-function', which are no
longer used by Emacs.  Please use PSGML 1.2.3 or later.

* The Calc package fails to build and signals errors with Emacs 21.

Apply the following patches which reportedly fix several problems:

* The `oc-unicode' package doesn't work with Emacs 21.

This package tries to define more private charsets than there are free
slots now.  If the built-in Unicode/UTF-8 support is insufficient,
e.g. if you need more CJK coverage, use the current Mule-UCS package.
Any files encoded as emacs-mule using oc-unicode won't be read
correctly by Emacs 21.

* ps-print commands fail to find prologue files ps-prin*.ps.

This can happen if you use an old version of X-Symbol package: it
defines compatibility functions which trick ps-print into thinking it
runs in XEmacs, and look for the prologue files in a wrong directory.

The solution is to upgrade X-Symbol to a later version.

* Using epop3.el package causes Emacs to signal an error.

The error message might be something like this:

  "Lisp nesting exceeds max-lisp-eval-depth"

This happens because epop3 redefines the function gethash, which is a
built-in primitive beginning with Emacs 21.1.  We don't have a patch
for epop3 that fixes this, but perhaps a newer version of epop3
corrects that.

* The arrow indicating the current execution line in GUD is invisible.

This was reported to happen when Emacs 21 is run on an xterm, and the
python-mode package was loaded.  It appears that python-mode is
incompatible with Emacs 21; newer versions of python-mode are likely
to fix that.

* On systems with shared libraries you might encounter run-time errors
from the dynamic linker telling you that it is unable to find some
shared libraries, for instance those for Xaw3d or image support.
These errors mean Emacs has been linked with a library whose shared
library is not in the default search path of the dynamic linker.

Similar problems could prevent Emacs from building, since the build
process invokes Emacs several times.

On many systems, it is possible to set LD_LIBRARY_PATH in your
environment to specify additional directories where shared libraries
can be found.
