OSX App Bundle not starting

Question

I have a problem with a Mac OSX app bundle. If I want to run my app bundle nothing happens (double clicking myApp.app).

I can run the app by executing ./myApp.app/Contents/MacOS/myApp without any problem.

The directory structure:

myApp.app/
    Contents/
        Info.plist
        PkgInfo
        Resources/
        Frameworks/
        MacOS/
            myApp

My Info.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>CFBundleDevelopmentRegion</key>
    <string>en</string>
    <key>CFBundleExecutable</key>
    <string>myApp</string>
    <key>CFBundleIconFile</key>
    <string>icon</string>
    <key>CFBundleIdentifier</key>

    <key>CFBundleInfoDictionaryVersion</key>

    <key>CFBundleName</key>
    <string>${PRODUCT_NAME}</string>
    <key>CFBundlePackageType</key>
    <string>APPL</string>
    <key>CFBundleShortVersionString</key>
    <string>1.0.0</string>
    <key>CFBundleSignature</key>
    <string>com.whatever.test</string>
    <key>CFBundleVersion</key>
    <string>1.0.0</string>
    <key>LSMinimumSystemVersion</key>
    <string>${MACOSX_DEPLOYMENT_TARGET}</string>
    <key>NSHumanReadableCopyright</key>
    <string>Copyright © 2014. All rights reserved.</string>
</dict>
</plist>

Edit:

Console.app result:

Answer 1

It was a working directory problem. using getcwd while executing "myApp.app" gives /

I fixed it by using the bundle dir instead of getcwd:

#include <CoreFoundation/CoreFoundation.h>

std::string getBundleDir()
{
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef resourcesURL = CFBundleCopyResourcesDirectoryURL(mainBundle);
    char path[PATH_MAX];
    if (!CFURLGetFileSystemRepresentation(resourcesURL, TRUE, (UInt8 *)path, PATH_MAX))
        return "";

    CFRelease(resourcesURL);

    chdir(path);

    return path;
}
