Greetings...I am attempting to install gnu-emacs on an IBM PC RT (running AIX 2.2) with 4 MBytes of memory. The compilation crashes at window.c in the .../src subdirectory. The error message is: Fatal error in ccom1: Memory fault *** error code 64 Any suggestions would be most appreciated. Please respond by mail; I unfortunately don't get to read news very much. Thanks in advance. -- Steve Wechsler | wechsler@leah.albany.edu Late at night, in the City of Angels, sometimes someone gets the urge to pet a small furry animal. That's where I come in.

Since you don't have very much memory (e.g. 4megs) and I suspect that GNU-emacs has some pretty big files, its possible that you don't have enough swap space to compile it. Because AIX doesn't preallocate swap space this is usually evidenced by a Memory fault at run time when the system has to page out part of your process (the compiler) and there isn't enough swap space (BSD at least tests before it gives you the memory so that once processes are given memory the system doesn't usually have to send a nasty signal to the process later on). Another possiblity if you can't easily add swap space is to get rid of all expendable processes to increase the available swap space. In particular, if you're running X windows, shut it down while you do the compile. Also you might be able to cut the compiler memory requirements by dropping out -O (if you're using that). ---------------------------------------------------------------- The above views are my own, not necessarily those of my employer.

The above does not jive with my experience. I've never gotten this sort of scenario when I've run low on paging space. What I've seen is that when you get low on paging space you get a "syncmode entered" message, with the warning "kill processes now" and then, before I can manually kill any processes, the system picks the most important process I'm running, such as the X server or GNUemacs and kills it, along with several others. :-) But I've never heard of getting a memory fault from being low on page space. My suggestion is to upgrade to 2.2.1 and get the latest version of emacs from prep. If you can't compile a particular file with -O, compile it manually without -O and then finish the compilation with -O. -- Nick Simicich --- uunet!bywater!scifi!njs --- njs@ibm.com (Internet)
