Irix with CC='gcc Martin> -mabi=64', for example. Don't forget the potentially most prominent platform (today, hopefully not tomorrow): 21.2/man/xemacs-faq.texi: ＠node Q6.4.1, ,Q6.3.3, MS Windows ＠unnumberedsec 6.3: Troubleshooting ＠unnumberedsubsec Q6.4.1 XEmacs won't start on Windows. (NEW) XEmacs relies on a process called "dumping" to generate a working executable. Under MS-Windows this process effectively fixes the memory addresses of information in the executable. When XEmacs starts up it tries to reserve these memory addresses so that the dumping process can be reversed - putting the information back at the correct addresses. Unfortunately some .dlls (For instance the soundblaster driver) occupy memory addresses that can conflict with those needed by the dumped XEmacs executable. In this instance XEmacs will fail to start without any explanation. Note that this is extremely machine specific. 21.1.10 includes a fix for this that makes more intelligent guesses about which memory addresses will be free, and this should cure the problem for most people. Unfortunately, no binary is yet available for this version. Check back periodically at ＠uref{ftp://ftp.xemacs.org/pub/xemacs/binaries/}. 21.2 implements "portable dumping" which will eliminate the problem altogether. You might have better luck with the 21.2 beta binary, available at ＠uref{ftp://ftp.xemacs.org/pub/xemacs/beta/binaries/}.
