I do not have experience on C++. And I have to use stasm for face detection. I'm traying to build the minimal example. On page 4 of this tutorial is possible to know what is necessary to make it work. But I'm these two errors:

What am I doing wrong? Can someone help me?
Thanks.
I've found a solution for this problem. If somebody has a problem like mine, you should enter on this site and use the CMakeList.txt and CMake to build Stasm. If you get any error you can try the intructions provides o the readme.

From GCC 5, A new ABI is enabled by default. In that new ABI, std::__cxx11 namesapce was introduced.
According to your error message, It seems that your program and OpenCV library you want to link with were build with different GCC version, which made incompatible binary.
For more information, you can read the following page:
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html

Can any one suggest what exact modification I have to do with the code in order to resolve the error
if anybody can help me to sort out this... It will be very helpful.
thank you.
link problem : ld can't find a definition of hdr_rtp_v2::access::Packet(Packet const*) and hdr_rtcp_v2::access::Packet(Packet const*), Constructors of Packet I guess.
This means you have not defined these functions
Or you forgot to link a lib
Or you are trying to link with ld a lib built with VC which use another name mangling causing this problem

And of course the header:
#ifndef __OgreTest__OgreInit__
#define __OgreTest__OgreInit__
#include <iostream>
#include <string>
#include <memory>
#include "OGRE/Ogre.h"
#include "MainLoop.h"
class OgreInit
{
public:
OgreInit();
~OgreInit();
private:
void initOgre();
void initScene();
MainLoop *mainLoop;
Ogre::Root *root;
Ogre::RenderWindow *window;
static Ogre::SceneManager *sceneManager;
Ogre::Viewport *viewport;
Ogre::Camera *camera;
Ogre::SceneNode *cameraNode;
};
#endif /* defined(__OgreTest__OgreInit__) */
I have seen this issue on Stackoverflow quite often, but usually it happened because some required libraries were not included. I don't think that is the issue here because I am not getting any errors if I change: static Ogre::SceneManager *sceneManager; to: Ogre::SceneManager *sceneManager;
Thanks in advance.
As well as declaring it in your header file, you need to actually define the sceneManager in your implementation file:
...
#if OGRE_PLATFORM == OGRE_PLATFORM_APPLE
#include "macUtils.h"
#endif
Ogre::SceneManager *OgreInit::sceneManager = 0;
OgreInit::OgreInit()
{
...
I have installed Eclipse+CDT and OpenCV with:
$ sudo apt-get install libcv1 libcv-dev libcvaux1 libcvaux-dev \
libhighgui1 libhighgui-dev \
opencv-doc \
python-opencv
After that I've opened Eclipse and created a new c/c++ project.
So I've typed this code:
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <cv.h>
#include <highgui.h>
int main(int argc, char *argv[])
{
IplImage* img = 0;
img=cvLoadImage("C:/.../Pictures/immagine.jpg"); // carica l'immagine
cvNamedWindow("mainWin", CV_WINDOW_AUTOSIZE); // crea la finestra
cvShowImage("mainWin", img ); // mostra l'immagine
cvWaitKey(0); // wait for a key
cvReleaseImage(&img ); //rilascia l'immagine
system("PAUSE");
return 0;
}
The problem is that I have these errors returned:
Unresolved inclusion: <cv.h>
Unresolved inclusion: <highgui.h>
But in my eclipse workspace project I have these libraries under /usr/include...
What may be wrong?
Thanks.
Open a terminal and execute:
pkg-config --cflags opencv
On my system it returns:
-I/usr/local/include/opencv -I/usr/local/include
Those are the directories you'll have to add on Eclipse to compile your application.
Or, you could try replacing your includes for:
#include <opencv/cv.h>
#include <opencv/highgui.h>
