MRufus:
I am working on latest distro of Ubuntu on Codeblocks and trying to compile this code


/*

 *
 * For macosx users, install ffmpeg (e.g. from fink) and recompile opencv this way
 * http://stackoverflow.com/questions/583969/compile-opencv-on-mac-with-ffmpeg-instead-of-quicktime

 */
#include "cv.h"
#include "highgui.h"

#include <iostream>

#define MISSING_FRAMES_TIMEOUT 10

using namespace std;
// Uncomment if you have OpenCV + FFMPEG
#define HAVE_FFMPEG
#ifdef HAVE_FFMPEG
extern CvCapture* cvCreateFileCapture_FFMPEG( const char* filename );
#endif

/**
 *   Main entry point of Motion. Launches all the motion threads and contains
 *   the logic for starting up, restarting and cleaning up everything.
 */
int main (int argc, char **argv) {

#ifdef HAVE_FFMPEG
  /* If i is 0 it means no thread files and we then set the thread number to 1 */

  string host("http://at@15.12.156.145/mjpg/video.mjpg");
 CvCapture *capture = cvCreateFileCapture_FFMPEG(host.c_str());
  string winBlobsName("Camera over network");
  cvNamedWindow(winBlobsName.c_str());
  while (capture) {
    // Grab frame
    int grab=cvGrabFrame(capture );
    if (grab<0) {
      cerr << "Error in capturing frame\n" << endl;
      break;
    }
    // Retrieve frame
    IplImage *img = cvRetrieveFrame(capture);

    cvShowImage(winBlobsName.c_str(),img);

    cvWaitKey(2);

  }
#endif
  return 0;
}

It requires Opencv and ffmpeg which I installed earlier. But when Im trying to compile the code it tells me

Compiling: main.cpp
g++: no input files
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings
 
If I try to run it it will say that it seems like this project has not been built yet. Would you like to build it? I say yes, it asks me the same question once more I say yes again and then nothing.
If I put in some simple code like hello world it works fine. Did anyone encounter this kind of problem before?

Jenna:
Please turn on full commandline logging and post the build log here:
change "Settings -> Compiler and debugger... -> Global compiler settings -> [the compiler you use] -> Other settings(rightmost tab)" "Compiler logging" to "Full commandline"

And please tell us which version of Code::Blocks you use.

MRufus:
here is a full build log

g++ -Wall -fexceptions  -g 'pkg-config opencv --cflags' 'sdl-config --cflags'     -c /home/rufat/Desktop/hello/TesttheFFMPEG/main.cpp -o obj/Debug/main.o
g++: no input files
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings
 

The version of Code blocks I'm using is 8.02

MRufus:
Additional info:

In order for it to recognize Opencv I had to go to Project build options -> Compiler Settings-> Other options and added
'pkg-config opencv --cflags'
'sdl-config --cflags'

Also in Linker setting -> Other linker options I added 
'pkg-config opencv --libs'
'sdl-config --libs'

It looks like you use an apostrope to surround the pkg-config stuff. You need a backtick ( "`" , french grave accent) here.
