For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
perl modules for c libraries

Posted by nevilleh (nevilleh), 11 September 2003
We have an application written in C and ported to multiple platforms. The application has an API also in C. We provide a perl module interface to that API.
However, we find there is a dependency between the version of perl used to generate the module. Consequently the module must be re-compiled for every version of perl that is used by a client.
Can anyone offer a way of creating the perl module API interface without the dependency to the version of perl?

Yes, Perl modules that include C (as yours will) do need to be compiled for the appropriate version of Perl - as I recall, it doesn't change with every Perl release, but certainly it does from time to time.

How much control over / access to your C application do you have? How complex (number of calls, etc) is the API?  I don't think I've an answer that will give you a solution in 5 minutes, but how about writing a little bit of "C" to offer the API as a service, then your Perl module could be pure Perl?   Could be very neat - or utterly impractical - depending on the metrics of your application!
