है, मुझे अपने क्लास ग्राफिक्स मैनेजर के साथ त्रुटियां मिल रही हैं।सी ++ त्रुटियां: 'grmanager' में सदस्य '...' के लिए अनुरोध जो गैर-वर्ग प्रकार 'ग्राफिक्स प्रबंधक'

अब तक मैं इस साइट पर कई त्रुटियों के लिए चारों ओर खोज की है और मेरी नवीनतम त्रुटि के साथ फंस गया है। अगर कोई इस समस्या में कुछ अंतर्दृष्टि प्रदान कर सकता है तो इसकी सराहना की जाएगी। मैं विंडोज विस्टा चला रहा हूं और Code::Blocksmingw कंपाइलर और SDL पुस्तकालयों के साथ उपयोग कर रहा हूं। यहाँ निर्माण संदेशों है:
