Var-Som-Dual i.mx6, Yocto, OpenCV

[andreascala]

Hello EveryOne !!!

I'm trying to build an OpenCV application on a Var-Som-Dual i.mx6 [yocto].

I've created the image file with the corretcs EXTRA_IMAGE_INSTALL....etc..

I wrote a code with just the #include<opencv2....> 

using namespace cv; using namespace std; int main(){ return0;};.....and it compile.

But when i add the simple line IplImage* image=cvLoadImage("Myimg",1);

the compiler says to me "undefined reference to cvloadimage".....

...the problem is that al the libraries (.so file) and the include are in the correct directory.....

....how can i fix that problem ????
