REVISED
I inherited this apache server from a Perl shop that I now work. When this web server was on ubuntu 14.04, I had no issues starting apache. I upgraded the server to ubuntu 18.04 and now apache does not start, here is the error
apache2: Syntax error on line 225 of /etc/apache2/apache2.conf: Syntax error on line 61 of /etc/apache2/sites-enabled/vhost.conf: no macro defined before Use
line 225 of main apache config
224 # Include the virtual host configurations:
225 IncludeOptional sites-enabled/*.conf
line 61 of vhost file
<IfModule perl_module>
Use Pconf /home/xxxx/xxxxx/xxxxx/htdocs 4 10 Hawaii
</IfModule>
This is where I am at a standstill, I have enabled the macro package.
Module macro already enabled
I can't start apache so there are no errors in the logs.
The error is trying to tell you that you need to define the macro Pconf before using a macro named Pconf.
The mod_macro: Usage documentation has an example that should help get you going.
