I'm in the process of trying to create a shared disk library.  The
problem is simple, actually:  it doesn't work! :-)

My question is this:  what shouldn't I be doing from a shared library
that I can do from a program that would be calling it?

If I link the library object directly with the test programs, they
work fine.  When I try using the shared lib, things start dying.
I'm getting seemingly random errors ... invalid address, F line
type opcode ( invalid opcode ), invalid instructions ... I can't
really figure it out.  

I followed it through the interface and it is ending up inside the 
code, but it is dying somewhere inside ...

I am using Manx FFP for the math inside the lib.  It seems to 
work.  I am passing in GfxBase, but that isn't relavent (yet! :-) since
it isn't in a routine that used any graphics routines.

To construct the lib I converted one of my source files to a format
usable my mklib and then took the output as a sample and did the
rest of the interface.asm and link.asm routines by hand.  

Anybody have any pointers about where I can start looking?  

Blair
