Hi All<br><br>Follow-up to the note below...<br><br>I compiled IGSTK in dynamic library format, and successfully call a<br>class in it from Slicer.</blockquote><div><br>I guess you were building on linux. <br><br>On windows you need to export the symbols using dllexport to tell the linker to make the symbol visible outside the dll. Since IGSTK doesn't define the dllexport directive, its equivalent to IGSTK having the entire dll as one module and all functions static (visible only within the dll).
<br><br>In slicer, each module is a shared library, loaded at runtime. So my guess is slicer on windows, when it opens the dll using dlopen, won't see any symbols in there. <br><br>- karthik<br><br></div><div><br><br>
