I am working on a swig prototype that interfaces CppAD Algorithmic Differentiation to octave, python, and perl. That should be enough to know it would work in general; see https://github.com/bradbell/cppad_swig The python version works under mingw-msys, but I am having some trouble linking the octave version. For example, I get the message swig_exampleOCTAVE_wrap.cxx:912: undefined reference to ` octave_value::octave_value(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, char)' my CMakeLists.txt code is locating the octave libraries that have a dll.a extension, to be specific -- octave_liboctinterp = C:/Octave/Octave-4.0.0/lib/octave/4.0.0/liboctinterp.dll.a -- octave_liboctave = C:/Octave/Octave-4.0.0/lib/octave/4.0.0/liboctave.dll.a It seems to me that these are import libraries because the have the '.dll.a' extension; see Answer 1 on http://stackoverflow.com/questions/6422478/linking-a-lib-and-def-files I cannot find the corresponding liboctinterp.dll and liboctave.dll to make sure they are in my windows path (so that the system can find them for dynamic linking). Is there some other dll that I am missing or do the '*dll.a' files contain the required routines and I just have the wrong linking conventions ?
Take a look in the C:/Octave/Octave-4.0.0/bin directory for the dlls, to link you should only need the export libs, unless cmake is trying to run some built executable whilst determining whether the libs work
