As mentioned earlier, I am trying to install Apache 2.2.9
onto z/OS 1.9. Had some difficulties, seem to have solved.
However, a few questions...
I started with the page
http://people.apache.org/~trawick/apache-2-on-os390.html
which describes a process for installing Apache 2.0 onto
OS/390. So, a similar code base, but somewhat dated. On
this page, the author asserts:
1. you need to get, in addition to the Apache tarball, the
GNU libtool, autoconf, and m4
Although I got these, it looks like I don't really need
them for Apache 2.2.9; it looks like these come along
with the Apache tarball.
Is this correct?
2. you need to run buildconf then configure
but the Apache instructions say you run configure, then make,
then make install
So, is buildconf no longer necessary? Or is it needed
for z/OS? (I actually had trouble with running it on
z/OS, getting an error message saying I needed python
installed.)
Now, here's some feedback to the developers: running
httpd-2.2.9/configure took over five hours!
While I realize I'm running on a weak platform (I'm only
on a ThinkPad, which runs Linux, which runs flex-es (which
simulates the z machine instruction set, so very slow, but
functional), which runs z/OS, it still seems a long time.
I saved and examined the stdout and config.log lines, and
it seems to me there is a lot of redundancy. It looks like
configure runs APR configure and other stuff. I see messages
like "checking size of char" at least two times. Now I see
that some of the checks can be time consuming. Can't you
build in some kind of memory, so if a check has been run
once at one level, it doesn't have to be run again at a
different level?

It can also use an optional file (typically called `config.cache' and
enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
