What do I need to link to gpib-32.obj in MinGW?

I want to link to ..\National Instruments\Shared\ExternalCompilerSupport\C\lib32\msvc\gpib-32.obj using MinGW. I used the new GPIB header and I made a import library (lib<name>.a) using pexports ("pexports gpib-32.dll > gpib-32.dll"). But when I try to compile, I get these errors:

..: undefined reference to `ThreadIbsta@0'

I think this is similar to http://forums.ni.com/t5/Multifunction-DAQ/Howto-use-NIDAQmx-with-mingw-gcc-3-4-2/m-p/294361, where the exports of nidaq32.dll (NI-DAQmx library) need to be first merged with the nicaiu.dll exports in order to create libnidaqmx.a. This can then be compiled in MinGW.

what language are you compiling this in?

It's C++ compiled with g++. The tooling & commands that I use to make the lib are:

 

pexports gpib-32.dll > gpib-32.defs

dlltool -k -d gpib-32.defs -l libgpib.a GPIB.DLL

 

The link above doesn't work. Use this link instead:
