BobLiu20 commented 8 years ago

I use python2 and cmake 2.8.

  1. enter test
  2. do 'cmake .'
  3. do 'make'
  4. lost of error happen.

for example: ''' In file included from /usr/local/include/opencv2/core.hpp:60:0, from my_lib_wrap.cxx:3309: /usr/local/include/opencv2/core/persistence.hpp:741:25: note: cv::FileStorage& cv::operator<<(cv::FileStorage&, const cv::String&) CV_EXPORTS FileStorage& operator << (FileStorage& fs, const String& str); ^ /usr/local/include/opencv2/core/persistence.hpp:741:25: note: no known conversion for argument 1 from ‘std::ostream {aka std::basic_ostream}’ to ‘cv::FileStorage&’ /usr/local/include/opencv2/core/persistence.hpp:1059:14: note: template cv::FileStorage& cv::operator<<(cv::FileStorage&, const _Tp&) FileStorage& operator << (FileStorage& fs, const _Tp& value) ^ /usr/local/include/opencv2/core/persistence.hpp:1059:14: note: template argument deduction/substitution failed: In file included from /usr/local/include/opencv2/core.hpp:3163:0, from my_lib_wrap.cxx:3309: /usr/local/include/opencv2/core/operations.hpp:3994:12: note: cannot convert ‘out’ (type ‘std::ostream {aka std::basic_ostream}’) to type ‘cv::FileStorage&’ out << "[" << p.x << ", " << p.y << "]"; '''

Do you have any idea for me ? Thank you .

renatoGarcia commented 8 years ago

It sounds like the std::ostream& operator<<(std::ostream&, <opencv type>) functions aren't being found. If that is the problem, you can solve it by putting an #include <file.hpp> inside a %header section of your SWIG project file, where <file.hpp> is the OpenCV source file defining that functions. What is the SWIG and OpenCV versions you are using? Could you share a minimal project that raise that error?

Hi , Thank you for your feedback. I just build your sample in test folder. it is lots of errors appear. Anyway , I also coding following your README.md , the same error again. My SWIG is 2.0.11 and OpenCV is 2.4.11. (By the way , python2 and cmake 2.8 in Ubuntu14.04)

@BobLiu20 I have added support to OpenCV 2.4.11 and Python 2. Could you please run the tests again? The only difference between ours systems is that I'm using SWIG version 3.
