Hi, I'm trying to export the following code to python, but failed. Please help me! Here is the code: -------------- c++ code: -------------- class IWorker { public: virtual int getData() = 0; };
class Worker : public IWorker { public: int getData() { return 100; } }; extern "C" { IWorker* createWorker(); } -------------- py++ code: -------------- mb.free_fun('createWorker').call_policies = call_policies.return_value_policy(call_policies.return_pointee_value) -------------- In python: -------------- >>> w = createWorker() I got 'TypeError: No to_python (by-value) converter found for C++ type: class IWorker I found that if the IWorker class is not abstract, for example: class IWorker { public: virtual int getData() { return 0; } }; Python doesn't report that error, but the result of the following code is not expected(I think it should be 100). >>> w = createWorker() >>> w.getData() 0 How to solve this problem? Please give some advise.
