I am trying to install the latest version of gnu emacs on an IBM RT
running AIX. I haven't succeeded yet; if anybody out there has
managed to bring up emacs on an AIX system, could you let me know what
I'm doing wrong?
Summary of my efforts:
* I am using the s- and m- files recommended in MACHINES.
* I added a line in m-ibmrt.h declaring STACK_DIRECTION to be -1.
alloca.c wouldn't compile without that.
* I am trying to compile it without X. (I have X Version 10, but
there's no need to be fancy yet.)
* I modified xmakefile so that the bsd library would be included:
several functions from it appear to be necessary.
* I am using the -g compiler switch rather than -O.
The program will now compile, but it dies immediately (it thinks that
it's receiving a signal 9) when I start it up. I can't find anything
useful with sdb.
Any advice?

If you're getting signal 9 (SIGKILL) during startup of Emacs, it probably means that the binary was created invalidly, which probably suggests that the unexec() logic is screwed for RT AIX. Sdb will tell you nothing, because the process is being killed with extreme prejudice by the kernel in the exec() logic when it detected (e.g.) bad alignment of the regions needed for your file. That is, the process isn't even getting started; main() (er, _start) was never called. Try forcing fewer heroics in unexec() by stipulating NO_REMAP and rebuilding from scratch. --Karl
