Just looking for general advice/guidance around creating Apache 2.4
modules, i have not been able to get any of the examples I've found
on-line to work.

I'm using Debian 9, Apache 2.4, FPC 3.0.4 and Lazarus 1.8.0

Did you read the "FPC and Apache Modules" wiki  page?

yep I've read Apache Modules page but was unable to get the example
working, I did use httpd24 etc.

I also found the following
32bit

freepascal_29.html
64bit

ubuntu-910.html

still no joy, I have a feeling I'm not loading the module correctly
under Apache 2.4

I'll just keep plodding, many thanks for you reply.

I would first check if your module has executable rights when
deployed: this is not automatically the case.

@Thaddy I checked the execute permissions and it was set, the error i
get when i try to restart Apache is

/usr/sbin$ sudo apache2ctl restart
apache2: Syntax error on line 231 of /etc/apache2/apache2.conf: Cannot
load /usr/lib/apache2/modules/mod_hello.so into server:
/usr/lib/apache2/modules/mod_hello.so: undefined symbol: ap_rputs
Action 'restart' failed.
The Apache error log may have more information.

i am out of my depth, but all part of the learning process

Right, getting nowhere fast with this one, so went back to the start
and double checked everything still no joy. So I removed Apache 2.4
and built 2.2.34 from source and recompiled the example so/dll I've
been working with, only changes I made was to use httpd22 rather than
httpd24 packages, it worked first time, did this to prove to myself I
was following the instructions correctly. I shall do some more digging
around Apache 24.4 and the httpd24 packages I sure its going to be
something really simple

the rights on the module make no difference - you can chmod 000
mod_hello.so and aoache2 will still load it fine

If you take a look at

https://github.com/graemeg/freepascal/blob/master/packages/httpd24/src
/http_protocol.inc

ap_rputs() is commented out. I believe ap_rwrite() or ap_rvputs() is
function that you need to write something. Example also use
ap_rwrite()
