c++ - 使用 SFML 和 Qt 窗口不显示

Question

在过去的 2 天里，我试图让 SFML 与 Qt Creator 一起工作，但它就是不起作用。该程序无法创建新窗口，我不确定原因。

应用输出

Starting E:\Programiranje\QT programi\build-SMFLConsoleGame-Desktop_Qt_5_3_MinGW_32bit-Debug\debug\SMFLConsoleGame.exe...
The program has unexpectedly finished.
E:\Programiranje\QT programi\build-SMFLConsoleGame-Desktop_Qt_5_3_MinGW_32bit-Debug\debug\SMFLConsoleGame.exe crashed

编译输出

你好哈布斯堡，欢迎堆栈交换!我目前没有设置来对此进行测试，但我怀疑您使用了错误的库。我注意到您正在使用 mingw，如果您查看 sfml 下载页面，则有两种类型的库(SJLJ 和 DW2)，使用错误的库可能会导致崩溃，但是调试输出可以提供更多关于问题。
