In another time sink I located the patches in com.unix.aux and was able to get Top 3.3 to compile for A/UX 3.x systems. My release notes:
I am pleased to announce the availability of Top 3.3 for A/UX 3.x:
This directory contains a pre-compiled version of top 3.3 for A/UX 3.1.1 as well as the source code from which the binaries were built.
It was compiled on an A/UX 3.1.1 Macintosh Quadra 700 using Apple's cc and make.
The included m_aux31.c machine module was buggy and would not compile with either cc or gcc. I tracked down a patch on comp.unix.aux that was never committed to the included machine module. Credit to Richard Henderson, who was responsible for top on A/UX, for this patch:
I was unable to use the patch files in A/UX or OS X, so I hand-applied the patches.
The three files patched, display.c, utils.c, and m_aux31.c, are included in this release.
Top is pretty machine-specific because it is looking at memory usage, etc. The patches should make this version of top run on any A/UX 3.x release.
Download and uncompress the top-3.3-aux-bin.tar.gz file:
gzip -dc top-3.3-aux-bin.tar.gz | tar xvfmo -
To install use CommandShell to navigate to the top-3.3-aux-bin directory and from within the directory type:
The parts will be copied to the correct locations (/usr/local/bin/top and /usr/local/man/top.man1) on your A/UX box.
