Something that will likely speed your transition is to split your task into as 
small of portions as possible, and tackle those one at a time from a higher 
level perspective.  For example, if a module is doing some custom 
authentication, look at what’s available in 2.4 already and see if something 
now stock can do the job, or at least get you 90% of the way there and serve as 
an updated template for your code.  For example, there are already modules for 
authentication providers like ldap, content caching, database access, etc.

The time savings on the simplified troubleshooting steps are likely to be far 
from insignificant, and you would have the benefit of a more 
standardized/modern codebase.  For example, get the server up and running with 
static content, then compile one module with apxs, get it to load, then work on 
the related config.  Work through any issues you find with this, then move on 
to the next.  This may be a good time to split one large config file up in many 
smaller ones with includes, etc.  Trying to migrate an existing non-trivial 
site in one step is likely to be overwhelming for most, especially for a novice.

In 2.4 itself the error is same.

The signature created turns out to be 00000000. I could not understand this 
part. I have gone through the internet and there are always some definite 
signature is available but in my case it turned out to be 0.

It is not a loadable library object.  Rather than fighting with cc's flags, 
review
the helper utility;

  https://httpd.apache.org/docs/2.4/programs/apxs.html

This will make your life much simpler for compiling and linking loadable 
modules. It retains the flags initially used for compiling httpd and modules, 
so that the results are consistent.
