Making C++ Loadable Modules Work

A question frequently popping up on comp.lang.tcl is why loadable modules written in C++ ``won't work''. Sometimes, they refuse to link, others refuse to load, and some link and load, but then crash for no apparent reason. I have spent a lot of research and experimentation into this subject and have distilled my experiences in these texts.

The Document

The document is available in several formats.

Files

Some files that are used or referenced.

module.cc A sample module that we want to load dynamically.
tclAppInit.c Slightly modified so that it can be compiled with a C++ compiler. Necessary on HP-UX using CC or aCC.
global.c An initialization function that g++'s ``collect2'' produces for example on HP-UX when linking an application. FYI only, you don't need this.
ctor.c A table of global constructors that g++'s ``collect2'' produces for example on Ultrix when linking an application.

Or, you can simply download tcl-c++.tar.gz containing all of the above.
