[Insight-users] Problem for building DLL from ITK

[Luis Ibanez]

Hi Bo,

Could you please post to the mailing list the source code
of the ITKLib32.cpp file ?

It is likely that you are missig some export symbols of the type:

    __declspec(dllexport)
    __declspec(dllimport)


Thanks


     Luis
