these are parameters to the run rule which I use. But I didn't write
it. I'm just a user of it.

But now that you've been sucked into the discussion, what about this:

in my test code I have the following statement:

     void * hDLL; // Handle to DLL
     hDLL = dlopen("", RTLD_NOW | RTLD_GLOBAL);
     BOOST_CHECK_MESSAGE((0 != hDLL), "Failed to find/load
plugin_polymorphic_derived2" );
     BOOST_CHECK_MESSAGE((0 != hDLL), dlerror() );

Which displays the messages

test_dll_plugin.cpp(196): Failed to find/load
plugin_polymorphic_derived2 in function 'int test_main(int, char**)'

test_dll_plugin.cpp(197): cannot open shared
object file: No such file or directory in function 'int test_main(int,

This code is meant to dynamically load the shared object named

It can't seem to find the shared object file named
"". OK so I went looking for it. I found the

ls */*/*.so*


which look to be the correct files several directory levels above the
tests. They also have unexpected names. How is my test program supposed
to find these? What should I do differently?
