Subject Re: [users@httpd] URGENT: Apache HTTP Migration from 1.3 to 2.0 UNIX Solaris
Date Wed, 14 Nov 2018 19:48:39 GMT
We have used the same compiler for both.

My main concern is "expected signature 41503234 but saw 00000000"

What could be the reason of signature 00000000?

This implies that no signature is generated in my case

Thanks & Regards

"External email. Open with Caution"

Do you use a "similar" compiler for httpd and the module?

'example_hooks_module' in file 
/app/quartz/COMS/EAI_324/ph/http/src/.libs/mod_example_hooks.so is garbled 
- expected signature 41503234 but saw 00000000 - perhaps this is not an 
Apache module DSO, or was compiled for a different Apache version?

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.

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.
