APR on OS390?

["Charles, Steve" <St...@tesseract.com>]

At the risk of displaying my total ignorance . . . 

I am investigating using APR on z/OS (OS 390) and have a few questions.

1)  Where can I find an OS390 version of APR.h ?
2)  Does APR require z/OS Unix System Services?
3)  Is there anything that would prevent APR from working with CICS?

build apr on your box and you get apr.h customized for your level of the OS

Please see http://www.apache.org/~trawick/apache-2-on-zos.html.  The 
instructions for building Apache will get you apr as well.  That should be 
reasonable for Apache 2 + apr 0.9.x.  (Bug me directly if you hit problems with 
Apache 2.0.x or apr 0.9.x.)

I have not tried to build apr 1.0 on z/OS since a little before Python was 
added as a prerequisite for natural development of APR 1.0.  There are a couple 
of issues to investigate:

1) is the somewhat odd autoconf 2.13 port I've always used really necessary, or 
will a configure generated elsewhere work on z/OS?
2) (based on outcome of #1) either skip the buildconf step totally or hack 
buildconf to use the configure created on z/OS but the make file input created 
elsewhere

yes

I have no idea.  An APR application is just a typical Unix app running on z/OS, 
so if those work with CICS in the way you desire then your APR application can 
work with CICS in the same way.
