undefined reference to `[email protected]'未定義的引用的WinMain @ 16個未知編譯指示
我運行的代碼塊,最新版本。我試圖編譯我在教程網站中找到的代碼,並且出於某種原因出現錯誤。我將我的項目設置爲DirectX9,並安裝了2010年6月的DirectX SDK。我也收到警告「未知的編譯指示」,即使編譯代碼也會無法正常運行。

問題太多了。看起來你只是在猜測。請閱讀初學者的書或教程。投票結束,這不是一個真正的問題。 –
您使用哪種編譯器?你得到的編譯錯誤告訴我它的gcc。無論如何,如果你試圖編寫一個Windows應用程序,你自己一個忙,並得到視覺工作室表達。隨着windows的sdk你有什麼版本的Windows。 – johnathon
