Q6.1.2: What compiler do I need to compile XEmacs?
--------------------------------------------------
- You need Visual C++ 4.2 or 5.0, with the exception of the Cygwin
-port, which uses Gcc.
+ You need Visual C++ 4.2, 5.0, or 6.0, with the exception of the
+Cygwin port, which uses Gcc. There is also a MINGW32 port of XEmacs
+(using Gcc, but using native libraries rather than the Cygwin
+libraries). #### More information about this should be provided.

* make sure HOME is set. This controls where you `.emacs' file comes
from;
- * CYGWIN32 needs to be set to tty for process support work. e.g.
- CYGWIN32=tty;
+ * CYGWIN needs to be set to tty for process support work. e.g.

+ You will need version b19 or later. The latest current version is
+1.1.1. Other common versions you will see are b20.1.
- You will also need the X libraries. There are libraries at
-`http://dao.gsfc.nasa.gov/software/grads/win32/X11R6.3/', but these are
-not b19 compatible. You can get b19 X11R6.3 binaries, as well as
-pre-built ncurses and graphic libraries, from:
+ Another location, one of the mirror sites of the site just mentioned,
+is usually a last faster:
+
+ `ftp://ftp.freesoftware.com/pub/sourceware/cygwin/'
+
+ You can obtain the latest version (currently 1.1.1) from the
+`latest/' subdirectory of either of the above two just-mentioned URL's.
+
+ *WARNING: The version of GCC supplied under `latest/', as of June
+6th, 2000, does not appear to work. It generates loads of spurious
+preprocessor warnings and errors, which makes it impossible to compile
+XEmacs with it.*
+
+ You will also need the X libraries. You can get them on the XEmacs
+FTP site at
+
+ `ftp://ftp.xemacs.org/pub/xemacs/aux/cygwin/'
+
+ You will find b19 and b20 versions of the X libraries, plus b19 and
+b20 versions of stuff that should go into `/usr/local/', donated by
+Andy Piper. This includes pre-built versions of various graphics
+libraries, such as PNG, JPEG, TIFF, and XPM. (Remember, GIF support is
+built-in to XEmacs.)
- `ftp://ftp.parallax.co.uk/pub/andyp/'.
+ (X libraries for v1 and beyond of Cygwin can be found on the Cygwin
+site itself - look in the `xfree/' subdirectory.)
+
+ _NOTE:_ There are two versions of the XPM library provided in Andy's
+packets. Once is for building with X support, and the other for
+building without. The X version should work if you're building with
+both X and Windows support. The two files are called `libXpm-X.a' and
+`libXpm-noX.a' respectively, and you must symlink the appropriate one
+to `libXpm.a'. *CAREFUL:* By default, the non-X version is symlinked
+in. If you then configure XEmacs with X, you won't run into problems
+until you start compiling `events.c', at which point you'll get strange
+and decidedly non-obvious errors.
+
+ Please see `http://www.xemacs.freeserve.co.uk/' (Andy Piper's home
+page) for more information.
+
+ BTW There are also libraries at
+`http://dao.gsfc.nasa.gov/software/grads/win32/X11R6.3/', but these are
+not b19 compatible, and may in fact be native-compiled.
