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:

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.
