openFrameworksLib.xcodeproj error in XCode

Hi everyone.
I’m trying OF for the first time, and I tried to configure XCode to work with it.

I’ve set up a new project using the projectGenerator, but when I open it I get one error:

/SDK/Frameworks/OpenFrameworks074/libs/openFrameworksCompiled/project/osx/openFrameworksLib.xcodeproj Couldn’t load openFrameworksLib.xcodeproj because it is already opened from another project or workspace

Now, the project works regardless, but I wonder how could I do to get rid of that problem.

Update: I closed the project, closed Xcode and restarted it. Now I don’t get the error, but when I do a run, it compiles correctly and then it doesn’t launch the app. No error is given, it just ends telling me everything went right, but nothing happens.

My testApp goes like this:

  
#include "testApp.h"  
int myCircleX;  
int myCircleY;  
  
//--------------------------------------------------------------  
void testApp::setup(){  
    myCircleX=300;  
    myCircleY=200;  
    ofSetFrameRate(60);  
}  
  
//--------------------------------------------------------------  
void testApp::update(){  
    myCircleX+=4;  
    if (myCircleX>1024)  
    {  
        myCircleX=300;  
    }  
}  
  
//--------------------------------------------------------------  
void testApp::draw(){  
    ofSetColor(120, 200, 200);  
    ofCircle(myCircleX, myCircleY, 60);  
    ofDrawBitmapString(ofToString(ofGetFrameRate())+"fps", 10, 15);  
}  

Hi
change your build target like this:

Oh, I guess I know nothing about XCode. Thanks for the tip, now it’s much clearer!
