c++ - How to combine template method pattern and multiple inheritance? -

-

can change code make work? possible combine template method pattern , multiple inheritance? seems convenient implement different algorithms in different classes. thank you.

class tbase { public:     virtual void do1() const = 0;     virtual void do2() const = 0;      void do() const {         do1();         do2();     } };  class tfirstalgorithm { public:     void do1() const {} };  class tsecondalgorithm { public:     void do2() const {} };  class talgorithm     : public tbase     , public tfirstalgorithm     , public tsecondalgorithm {};

fundamentally, problem tfirstalgorith::do1 isn't related tbase::do1 (and likewise tsecondalgorithm::do2 tbase::do2.

one possible way fix make them related:

class tbase { public:     virtual void do1() const = 0;     virtual void do2() const = 0;      void do() const {         do1();         do2();     } };  class tfirstalgorithm : public virtual tbase { public:     void do1() const { } };  class tsecondalgorithm : public virtual tbase { public:     void do2() const { } };  class talgorithm     : public tfirstalgorithm     , public tsecondalgorithm {};

c++ - Troubles when compiling phash program -

here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
