I downloaded the Intel C/C++ compiler for x86 architectures and have been running with it in order to add some spice to my life. I have discovered some interesting things: 1. By default, 21.4 will only build with this compiler if I configure with pdump. If I try to configure --pdump=no, I get an error because -lgcc is not a valid library. This aborts configure because sizeof(short) = 0. 2. If I edit src/s/linux.h and #define ORDINARY_LINK, I can configure and build successfully. However, upon first run, I get an error which looks suspiciously like the HANNIBAL LECTOR error: gdb /opt/build/xemacs-21.4-2003-01-09-1600-icc3/src/xemacs core then type `where' at the debugger prompt. No GDB on your system? You may have DBX, or XDB, or SDB. (Ask your system administrator if you need help.) If no core file was produced, enable them (often with `ulimit -c unlimited' in case of future recurrance of the crash. Lisp backtrace follows: # bind (frame-being-created) make-frame(nil #<x-device on ":0.0" 0x1d64>) frame-initialize() # bind (debugger debug-on-error command-line-args-left) command-line() # (condition-case ... . ((t (byte-code " o‡" ... 1)))) # bind (error-data) normal-top-level() # (condition-case ... . error) # (catch top-level ...) zsh: segmentation fault (core dumped) src/xemacs 3. In fact, it was our old friend Hannibal, because, when I ran configure with LDFLAGS='-z nocombreloc', I could successfully run my shiny new XEmacs. 4. While building (either with or without pdump, I noticed a number of warnings: /opt/src/xemacs-21.4-2003-01-09-1600/src/emacs.c(2915): warning #556: a value of type "void (*)(void *)" cannot be assigned to an entity of type "void (*)(void *, const void *)" __free_hook = ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/emacs.c(2989): warning #556: a value of type "void (*)(void *)" cannot be assigned to an entity of type "void (*)(void *, const void *)" __free_hook = ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/process-unix.c(236): warning #266: function declared implicitly master_fd = getpt (); ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/process-unix.c(292): warning #266: function declared implicitly slave_name = ptsname (master_fd); ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/process-unix.c(292): warning #556: a value of type "int" cannot be assigned to an entity of type "const char *" slave_name = ptsname (master_fd); ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/process-unix.c(321): warning #266: function declared implicitly grantpt (master_fd); ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/process-unix.c(335): warning #266: function declared implicitly unlockpt (master_fd); ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/glyphs.c(1992): warning #186: pointless comparison of unsigned integer with zero assert (XIMAGE_INSTANCE_YOFFSET (image_instance) >= 0 ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/glyphs.c(1992): warning #186: pointless comparison of unsigned integer with zero assert (XIMAGE_INSTANCE_YOFFSET (image_instance) >= 0 ^ /usr/local/intel/compiler70/ia32/bin/icc -c -O3 -mcpu=pentiumpro -tpp6 -march=pentiumiii -axK -ip -Demacs -I. -DHAVE_CONFIG_H -I/usr/local/include -I/usr/X11R6/include /opt/src/xemacs-21.4-2003-01-09-1600/src/glyphs-eimage.c /opt/src/xemacs-21.4-2003-01-09-1600/src/glyphs-eimage.c(1286): warning #186: pointless comparison of unsigned integer with zero for (i = height - 1; i >= 0; i--) ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/redisplay-x.c(980): warning #167: argument of type "long *" is incompatible with parameter of type "unsigned long *" if (!XGetFontProperty (xfont, XA_UNDERLINE_POSITION, &upos)) ^ /opt/src/xemacs-21.4-2003-01-09-1600/src/redisplay-x.c(982): warning #167: argument of type "long *" is incompatible with parameter of type "unsigned long *" if (!XGetFontProperty (xfont, XA_UNDERLINE_THICKNESS, &uthick)) I hope someone finds all this interesting. - Vin
