[Dev-C++] Re: Creating import libraries

[DXFX <vin...@ed...>]

I'm sorry, but I stated it wrong...

I have the DLLs, precompiled for me. Particularly, the .DLL files is what I have.

What I know is to use this DLLs in new programs, I have to make interface libraries for the DLLs... How do I do that? I've been trying to use dlltool with this purpose. I'm using the following in the command line...

dlltool -D MyDLL.dll -l MyDLL.a

and the interface library comes out just fine. However, When I try to compile programs linking with the library, I'm still getting undefined references to functions. I have made a header file for the library, which contains the DLLs exported functions... but when I compile, I get the an undefined reference to the functions.

Am I doing the thing right? I created the import/interface library then created my own header files. I included this header files with my code, then linked with the interface library... was it right?

Let me guess you are using the mingw-compiler?

Got some problems with it myself here
	http://www.cygwin.com/ml/cygwin/1999-12/msg00382.html
is a bug report which talks about 'interesting link time errors'.

Some of my problems (all of my 'undefined references') get solved by 
switching to the cygwin compiler. The Problem with the cygwin compiler 
is it isn't the easiest to install and its 'stdlib.h' does not declare 
the itoa(..)function which I personally need.

So this tradeoff is on yourself.

If you are not shure if your libs are OK pack them via the ar-tool from 
cygwin.
The command
	ar rsc libWhateverYouWant.a *.o
packs all object code into the lib file 'libWhateverYouWant.a' which get 
used by Dev-C++ as -lWhateverYouWant

Hope this helps
