XEmacs is reasonably 64 bit clean, but it's been fairly difficult getting it that way and it's easy to break and a royal pain to debug when things go wrong. You need to isolate where in the code it's crashing, then look over diffs between it used to work and now to see what has changed. Which distribution of Linux are you using? (and kernel, gcc, glibc, binutils versions, etc.)

xemacs crashes immediately on Alpha Linux 25 years, 1 month

Falk Hueffner

Hi, when building xemacs from CVS, it crashes at this point: [...] Loading /usr/local/src/xemacs-21.2/lisp/itimer-autosave.elc... Loading /usr/local/src/xemacs-21.2/lisp/printer.elc...

SL Baur

The main tarballs contain many empty directories in lisp/. I think the simplest fix is to add the line: checkout -ko -P to ~/.cvsrc in the account being used to generate them. In the meantime, it might be a good idea to do a 21.1.11 quickly. Quail is definitely broken by the current state. [Thanks to Maxime Froment for bringing this to my attention.]

directory-files and case search 25 years, 1 month

Didier Verna

Since this function can perform matching based on regular expressions, it should handle the case folding facilities offered to the programmer. The most logical and natural way to achieve this is IMO to make it respect the variable `case-fold-search'. The drawback is that it might then be affected by some current-buffer settings (case-fold-search itself, plus some other stuff, see `fast_string_match'). If we do this, we take the risk of breaking existing code. Of course, I'm willing to fix all core and external packages that we distribute. But do we want to do this change ? Another alternative would be a new flag, but I hate this. This function has already too many insane flags, and the long term solution would probably be to to write a better designed replacement for it.

ring-insert, pcl-cvs, and vc-cc 25 years, 1 month

Raymond Toy

Previously, Adrian mentioned the problem with ring-insert and pcl-cvs v2_9_9 where pcl-cvs was calling (ring-insert vc-comment-ring <string>) but vc-comment-ring was nil. I didn't see any patch or comments in the mail archives so here is my patch. Without it, I can't commit anything with pcl-cvs. It's a bug in vc-cc/vc.el for not initializing vc-comment-ring to a ring.

This is all taken care of by the standardized XEmacs dynamic-module interface. Dynamic modules must define several functions and constants for Xemacs to find it and properly load it. These must be exported from the DLL, so it wouldn't be too hard to create a .h file (with ellcc or make the user do it) with #if defined(WIN32) && defined(HAVE_SHLIB) #define EXPORT __declspec(dllexport) #define IMPORT __declspec(dllimport) #else #define EXPORT #define IMPORT #endif (or put that in symdll.h or somewhere nice). Then make the user put EXPORT in front of all of these standard symbols (defs_of_<module>, syms_of_<module>, etc.) > > 2.

I needed these: Qt DATA message defsubr dumpopaque Qnil DATA staticpro defvar_magic assert_failed make_uninit_string Fbuffer_substring Fcons Ffind_face Fintern alloc_lcrecord gcprolist DATA print_readably DATA signal_simple_error write_c_string boolean_specifier_methods DATA display_table_specifier_methods DATA image_specifier_methods DATA integer_specifier_methods DATA generic_specifier_methods DATA natnum_specifier_methods DATA toolbar_specifier_methods DATA lrecord_implementations_table DATA lrecord_markers DATA lrecord_type_count DATA As you can see, some of them are symbols, some are functions... You need a macro like this: #if defined(WIN32) && defined(HAVE_SHLIB) #ifdef BUILDING_XEMACS #define EXTERNAL __declspec(dllexport) #endif #ifdef BUILDING_MODULE #define EXTERNAL __declspec(dllimport) #endif #if defined(BUILDING_XEMACS) && defined(BUILDING_MODULE) #error "BUILDING XEMACS and BUILDING_MODULE both defined!" #endif #if !defined(BUILDING_XEMACS) && !defined(BUILDING_MODULE) #define EXTERNAL #endif #else #define EXTERNAL #endif and then put EXTERNAL in front of all Xemacs symbols and functions that potentially may be used by dynamic modules. Since I couldn't hope to guess what a module may or may not use, I'd just as soon as put EXTERNAL in front of every non-static symbol. If you do this, you won't need to define the export library for XEmacs (just #define BUILDING_XEMACS), though you will still need the import library for compiling the DLL (where you'll #define BUILDING_MODULE). andy > > These kinds of mechanisms eliminate the need to do what you > describe below. > From your description, I suspect that some significant work > needs to be > done with regard to defining the API. > > What would be extremely useful is if you could make a list of > the kinds of > things that you need access to in the application and another > list of the > kinds of things that you expect to provide to the > application.
