Paul, if your compiled code doesn'thave any references to the symbols defined
in the dictionary, the object module from the dictionary may not be linked in.
When (in your example #2) you load the library explicitly, you get the correct
behaviour. Therefore you may
- either to compile the dictionary into a separate library and to load it in
at run-time using
gSystem->Load("your_library");
from the compiled code
- or to force linker to link the dictionary by declaring one of the global
symbols defined in the dictionary as external in your code.
regards, pasha
