[Dev-C++] Problems with linking to a VC++-lib

Dear list members,

I am quite new to windows and C++ programming (did quite much C under 
unix up to now).

My task is to write a program using a proprietary C++-API (device 
driver) which I only have in a binary version for VC6 or VS.net. I 
can compile using VC6, but would like to switch to Dev-C++ or plain 
MinGW/gcc. However, when linking against the library, I always get 
"undefined references" for the methods contained in the library.

I tried converting the library using reimp, but apart from that it 
works other than expected (it gives me a bunch of object files that I 
can then again put together to a library using ar) this does not make 
any difference.

The API in question can be found here:
http://www.dektec.com/Downloads/Drivers.asp
(same results with both VC6 and VS.NET version).

My program is at the moment a modified version of "DtRecord" on the 
page "utilities", to get started.

As already said, everything works fine with VC6, but I really would 
like to move to gcc for using GTK+ and other stuff... I am using dev-
C++ 4.9.9.2 in the "full" version (including MinGW).

I am not sure if it is really a "typical" VC++ problem or simply a 
difference in calling convention - but in the latter case, I have 
even less clue about how to get around it. Here an example nm output 
of the Symbol TsOutpChannel::SetTsRateBsp:
My_Example.o:
U __ZN13TsOutpChannel12SetTsRateBpsEii
DTAPI.lib:
00000000 T ?SetTsRateBps@TsOutpChannel@@QAEKHH@Z
For me it looks really strange, but I have absolutely no idea about 
symbol names in C++, so maybe somebody else can say more seeing these 
symbols...

In case I left out some important information, please let me know.

Regards,
Wolfgang
