I am currently trying using OpenCV with wxDev-C++, and I have tried compiling the following code:

 #include <"C:\OpenCV\build\include\opencv2\core\core_c.h">
#include <"C:\OpenCV\build\include\opencv\cxcore.h">
#include <"C:\OpenCV\build\include\opencv\highgui.h">


int _tmain(int argc, _TCHAR* argv[])
{
    IplImage *img = cvLoadImage("D:\Projects\display_image\lel.bmp");
    cvNamedWindow("OpenCV",1);
    cvShowImage("OpenCV",img);

    cvWaitKey(0);
    cvDestroyWindow("OpenCV ");
    cvReleaseImage(&img);

    return 0;
}

I get this error when I compile the code: "Invalid argument" and "D:\Projects\display_image\Makefile.win [Build Error] [Objects/MingW/display_image.o] Error 1"

I think this might be because of how I modified the compiler options. Here are the stuff I added under Compiler options:

I have added the following commands to the linker command line under Compiler options:
-lcxcore -lcv -lhighgui -lcvaux -lcxts -lml

And added this directory to the "Binaries": C:\OpenCV\build\x86\mingw\bin

Added this to "Libraries": C:\OpenCV\build\x86\mingw\lib

And added the following directories to C and C++ Includes:
C:\OpenCV\include\opencv
C:\OpenCV\build\include\opencv
C:\OpenCV\include\opencv2
C:\OpenCV\build\include\opencv2

I'm not sure if what I did is correct.

Thanks in advance

I don't use wxDev-C++, so this maybe a stupid question. Is there a way to tell the IDE to give you verbose build logs? If so, use that option so that it will show you how it is exactly calling the compiler and/or the linker.

If you don't understand the output, don't worry. I'm quite sure that if you post the verbose logs here, somebody will be able to decipher it and lead you to a fix.

Try removing the <> from your includes.

#include "C:\OpenCV\build\include\opencv2\core\core_c.h"

If you give the full path you should be using quotes, But you should never use both quotes and <>.
