copied!<p>I'll do the best I can with this, given not much Perl knowledge.</p> <p>It looks to me like the <a href="http://perldoc.perl.org/DynaLoader.html" rel="nofollow">Dynaloader</a> in perl is a utility that lets you load dynamicly loadable libraries (lib*.so's on Unix systems) into a perl program.</p> <p>For that to work for an Ada program, there are several things you'll need to take into account.</p> <ol> <li>You need to build your Ada program as a proper dynamic library. It looks like you did that. However, I'm no expert on this, so perhaps you missed something. I'd highly suggest looking over TFM on this.</li> <li>You need to call your Ada code properly. Ada programs generally require a process called "elaboration" be performed before any actual code may be run. To accomplish this, most Ada compilers create a special entry-point to the program, rather than just using the one associated with your "main" routine. I think Gnat's is something like <code>C_yourprogramname</code>, but don't hold me to that. Even if you are implementing a library of some sort, the elaboration should be run first (execpt in some special circumstances, that do not apply here). However, if you want a routine to be a library routine called from outside of Ada, you generally don't want a "main", so there are some extra steps. How to do this with Gnat is <a href="http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Binding-with-Non_002dAda-Main-Programs.html#Binding-with-Non_002dAda-Main-Programs" rel="nofollow">described in their user guide</a>, but in general it involves telling the compiler to not make a "main", calling <code>adainit</code> before running any Ada routine from outside, and calling <code>adafinal</code> when you are all done.</li> </ol>
