Dear XEmacs developers and users,
I am attempting to compile the native port of XEmacs (tip of the
"default" branch in https://bitbucket.org/xemacs/xemacs) with VS 2015
Community ('free') edition on a Windows 7 64-bit machine. I saw HST's
report at http://list-archive.xemacs.org/pipermail/xemacs-beta/2015-July/025761.html,
and applied the patch in that email to the tip. (It sounded like the
patch allowed HST to compile a working copy of XEmacs). Unfortunately,
the copy I end up with crashes in pdump, with the following stack
trace (viewed in WinDbg):

The line at which the segmentation violation occurs is marked with an
ASCII arrow:
/* Put back the pdump_root_block_ptrs */
p = (Rawbyte *) ALIGN_PTR (p, pdump_static_pointer);
for (i = 0; i < header->nb_root_block_ptrs; i++)
{
pdump_static_pointer ptr = PDUMP_READ (p, pdump_static_pointer);
#ifdef NEW_GC
(* ptr.address) = (Rawbyte *) pdump_get_mc_addr (ptr.value);
#else /* not NEW_GC */
-> (* ptr.address) = ptr.value + delta;
#endif /* not NEW_GC */
}
The header record looks like this:
dt header
Local var @ 0xa8daf8 Type pdump_header*
0x010c32b0
+0x000 signature : [8] "XEmacsDP"
+0x008 id : 0x55fabbe2
+0x00c stab_offset : 0x22df98
+0x010 reloc_address : 0
+0x014 nb_root_block_ptrs : 0n76
+0x018 nb_root_blocks : 0n135
+0x01c nb_cv_data : 0n0
+0x020 nb_cv_ptr : 0n0
the ptr record looks like this:
dt ptr
Local var @ 0xa8daa8 Type pdump_static_pointer
+0x000 address : 0x00906014 -> ????
+0x004 value : 0x001ccc74 "--- memory read error at
address 0x001ccc74 ---"
The memory at ptr.address doesn't appear to be accessible (hence the crash).
I have checked the FAQ/PROBLEMS, and none of the entries about pdump
crashes appear to apply: I am not compiling with optimization, and I
am not trying to use system's memory allocator under Cygwin. The
crash does reproduce reliably for me, so I can keep poking at it.
Does someone have suggestions on where to look next?
On another note, i.exe causes an assertion failure for me as well (HST
worked around it by not using i.exe, but it isn't clear how batch
compilation would work without i.exe).

Hello
This seems a odd problem, I can bind in Emacs/Xemacs
The left/right arrow keys, like
control+left, or left (alt/hyper/super)+left
but *not* shift+left.
Somebody has an idea?
thanks
Uwe Brauer

Hello
Since GNU emacs has now Bidi support I am starting to use it more
often, so naturally I came across their package system.
Here are a couple of comments and some suggestions.
1 I cannot judge how difficult it is to maintain a GNU emacs
package (and to generate one).
2 I tested in only on Linux Kubuntu, so I don't know who it works
on other platforms, but I would guess that there is not much of a
difference.
3 from a user point of view GNU emacs pkg system seems easier to
use, because:
4 you just have to type: package-list-packages, no need to set up a
server, no need to download a database.
5 once you fire up that command a list of available packages is
presented and it is described which pkg is official and which is
beta. That is more comfortable than the Xemacs approach where you
have to download two different database files.
6 if you as user want to install a beta package, it will be
installed in your local home directory ~/.emacs.d which is the
equivalent of ~/.xemacs/xemacs-package. So it is not necessary to
run GNU emacs as root.
7 there is no conflict between the experimental package and the
official one. As I understand if GNU emacs finds two packages, it
chooses the one which is installed in the user home directory. I
tried that out, installing an experimental pkg for GNU emacs 25
and then calling GNU emacs 24 and it complained. GNU emacs 24
could be only run when this packages was uninstalled.
As I wrote in my recent bug report, we have already feature 6, but it
seems that feature 7 is not implemented. So I suggest to give that
feature a try.
