Hi there,
to learn how to use dlls I used the IDL example code for simple_vars. But
instead of using nmake, I wanted to move the compilation process inside
Visual C++ (with nmake everything works fine).
So I built a dll frame with the wizard and included stdio.h and export.h in
StdAfx.h, and linked to idl32.h
I also moved the function definition:
int IDL_STDCALL simple_vars(int argc,void* argv[])
{
snip
}
as is into my .cpp file, and the function declaration in the header file.
Everything compiles and links fine, but I get the following eror after
calling simple_vars from idl54:
% CALL_EXTERNAL: Error loading sharable executable.
Symbol: simple_vars, File =
C:/users/joern/ccode/idl/MyExternal/DEBUG/MyExternal
ERROR_PROC_NOT_FOUND
% Error occurred at: SIMPLE_VARS 62
C:\users\joern\Ccode\Idl\MyExternal\simple_vars.pro
% $MAIN$
What the hexter does that mean?
Thanks, joern

Thanks Ronn, and
yes, I included idl32.lib, and no I didn't include the .def file, but used
_declspec(export) instead.

Joern,
First let me recommend that you go straight to using DLM's and skip
call_external. You will be much happier with the results.
Now, you really meant idl32.lib not idl32.h, right? Assuming that is correct
did you include the call_examples.def file in the project? I avoid using
call_external so I don't know if you also need to have an export file, but
that might be a problem also.
If you want to get a really good book on calling C from IDL using DLM's go
to http:\\www.rkling.com and click the link to "Books on IDL" at the top of
the page;) Of course, I am biased on the book but I have received a ton of
positive comments on it!
