OF crashing when compiling more than once

x-code
#1

Hi,

I have written an openFrameworks application in Xcode which communicates with an Arduino Nano board using ofArduino.cpp.

When I first start up my computer, then the first time I compile the code it works fine, and the application runs and can be closed as expected. However, if I then compile/launch the app again, the whole system crashes and I have to turn the computer off by holding down the power button.

When this happens, it SOMETIMES flashes up with this error:
GBD: Program received signal: “EXC_BAD_ACCESS”

But this is not consistent, and appears in a different place each time (sometimes in the ofArduino.cpp file, sometimes in the ofTrueTypeFont code…)

I’m totally stuck… any help much appreciated!

#2

The same error for me with different arduino boards.

#3

Actually i’m receiving.

Program received signal: “EXC_BAD_ACCESS”.
sharedlibrary apply-load-rules all
warning: Could not find object file “/Users/theo/Documents/CODE/__OPENFRAMEWORKS/SANDBOX/COMPILE_LIBRARIES/buildGlutFramework/libForeground.a(macx_foreground.o)” - no debug information available for “/Users/mcast/Code/GLUT-ToPost/macx_foreground.m”.

And Xcode is pointing to line 453 of ofArduino and processSysExData method.

Any help?

Thanks

I have the same problem “EXC_BAD_ACCESS” on line 506 of ofArduino.cpp. I’m using of 0.8.1. on Yosemite.
Any idea?
It appears 8 times on 10, when i run my app.

#5

can you post your code?

Hi Zach, the code is from the example “firmataExample”. I just changed the string of my serial port. Sometimes works, sometimes not.
But here you can find the code of my project and there is the same problem:

void ofApp::setup(){
  ofSetVerticalSync(true);
  ofSetFrameRate(60);
  ofBackground(0);
  ofEnableAlphaBlending();
  ofSetCircleResolution(100);
  ard.connect("/dev/tty.usbmodemfd141", 57600);
  ofAddListener(ard.EInitialized, this, &ofApp::setupArduino);
  bSetupArduino	= false;
}

void ofApp::update()
{
  updateArduino();
}


void ofApp::setStations(int pinMin, int pinMax)
{
  for(int pin = pinMax; pin <= pinMax; pin++)
  {
    setStation(pin);
  }
}

void ofApp::setStations(int totStations)
{
  for(int pin = 0; pin < totStations; pin++)
  {
    setStation(pin);
  }
}

void ofApp::setStation(int pin)
{
  ard.sendAnalogPinReporting(pin, ARD_ANALOG);
}

int ofApp::getTotStations()
{
  return stationsValues.size();
}

//--------------------------------------------------------------
void ofApp::setupArduino(const int & version)
{
  ofRemoveListener(ard.EInitialized, this, &ofApp::setupArduino);
  bSetupArduino = true;
  ofLogNotice() << ard.getFirmwareName();
  ofLogNotice() << "firmata v" << ard.getMajorFirmwareVersion() << "." << ard.getMinorFirmwareVersion();
  setStation(5);
  ofAddListener(ard.EAnalogPinChanged, this, &ofApp::analogPinChanged);
}

void ofApp::updateArduino()
{
  ard.update();
  if (bSetupArduino)
  {
  }
}

void ofApp::analogPinChanged(const int & pinNum)
{
  cout << "analog pin: " + ofToString(pinNum) << " = " << ofToString(ard.getAnalog(pinNum)) << endl;
}


//--------------------------------------------------------------
void ofApp::draw()
{
  ofSetColor(255);
  if (!bSetupArduino)
  {
    cout << "arduino not ready..." << endl;
  }
  else
  {
  }
}

do you see any difference in what’s printed to the console ?

#8

Now it crashed just one time on my project and zero on the example.
In che console i had the same output

[notice ] ofSerial: [0] = tty.usbmodemfd141
[notice ] ofSerial: [1] = cu.usbmodemfd141
[notice ] ofSerial: [2] = cu.Bluetooth-Modem
[notice ] ofSerial: [3] = tty.Bluetooth-Modem
[notice ] ofSerial: [4] = tty.Bluetooth-Incoming-Port
[notice ] ofSerial: [5] = cu.Bluetooth-Incoming-Port
[notice ] ofSerial: opening /dev/tty.usbmodemfd141 @ 57600 bps
[notice ] ofSerial: opened /dev/tty.usbmodemfd141 sucessfully @ 57600 bps
[notice ] StandardFirmata.ino
[notice ] firmata v2.3

and also this when it crashes

(lldb)

Really don’t understand :-\
