Dear Ed & others,
Many thanks for your reply! A inline module sounds (much) better, but looking
through the documentation it seems a bit beyond my current skill level.
If you/someone else on the list would be available to implement this as a small
project, please let me know! I have some funding available.
But for now, I'll use inline:CPP directly - and to clarify my previous
explanation, the "dlib/matrix" is indeed an external library that will not be
found automatically..
So, I've looked at the Inline C documentation, and probably need something like
this in Inline Cpp format:
use Inline C => config => libs => '-L/your/path -lyourlib';
I also need to provide the following commands to the GCC compiler:
'-std=c++11 -O3 -fopenmp'
but haven't found any documentation on this yet..
And I need to make sure that inlines writes to a location where it has
read/write permission:
use Inline (Config => DIRECTORY => '/usr/local/apache/Inline', );
because I my survey system uses CGI (wasn't aware of this before, but I noticed
this in the Inline C documentation)
Could you/someone else show me how to implement this (correctly) in the Perl
script below)?
Many thanks,
Marcel
