I have some classes that are defined in C using the xotcl (cersion 1.4) C API. Things seem to work (I can create objects and invoke methods), but I can't get chaining to function. I can invoke the "next" command (using Tcl_Eval( interp, "xotcl::next")), but that fails with "next: can't find self"
I've stepped into the XOTcl code and it looks like it's searching the the interpreter's call stack to determine the active object but as near as I can tell, my C-defined methods don't correctly annotate Tcl's call stack.
I'm not aware of any documentation for the C API, so I used the library code (xotclsdbm.c) as an example. Is there anything I need to do beyond XOTclAddIMethod to get "next" to function? I'm using a locally built version of XOTcl (the binary versions don't include header/libs). Is it possible I've built something incorrectly? I see two defintions for the RUNTIME_STATE macro which looks like it plays a role in this. I don't know which version I'm using or if it even matters, but I assume I'm using the default version.
