Hi all, For my Machine Learning toolkit, I'm looking to draw on the work of either the Java Weka ML system or the MLC++ library. My question to the Drupal community is: which is easier to bridge (Java or C++) to PHP (and specifically to Drupal)? My vote is for Java, as I can distribute the (GPL'd) bytecode more easily than pre-compiled C++ binaries. Let's take performance off the table for this discussion. My design calls for the ML algorithms to be pluggable via an API to the interaction code, so high perf classifiers could be written later if my selected method proves slow. On a more general note, do any modules currently require php extensions that are not in PEAR? If so, how do they handle getting the module compiled and installed. Thanks, Mark Fredrickson
