Re: Need help with loading .SO file

Otherwise the symbols of your *.so get mangled (c++ - style) and the

BTW if you don't have to use C++, you can simply rename your file to
"Proc.c". This way the C compiler is used and no name mangling occurrs.

Strictly, the C compiler does name mangling too, but the mangling it
does is really very simple; it just puts an underline in front. In the
case of C++ though, things are more horrible since the type of the
function is encoded in the mangled name and IIRC not all compilers use
the same method for doing this. This is why Tcl doesn't try to figure
it out, and since C linkage is perfectly adequate for this and has to
be supported by the compiler anyway, there's no incentive to change.
