NetBeans不編譯openGL項目

我在Netbeans中編程，使用MSYS，Qt，mingw和openGL，並想知道如何解決鏈接器問題。NetBeans不編譯openGL項目

myWindow.h

這似乎是你在編譯（或更具體地說，鏈接）過程中不包括QtOpenGL模塊。

如果您使用.pro文件爲您的項目，你將需要添加QT += opengl吧，告訴你使用QtOpenGLqmake。其他構建系統可能需要你做不同的事情。

當使用NetBeans管理配置時，如果進入項目屬性，在Build - > Qt下，應該有用於各種Qt模塊的複選框，其中包括QtOpenGL。在這裏你可以啓用/禁用鏈接到任何Qt模塊。

在NetBeans中，沒有.pro文件，我不知道如何將此語句添加到此文件 – test1604 2012-02-13 13:48:47

根據輸出結果，它似乎會*使用'qmake'和'.pro 'file'nbproject/qt-Debug.pro'，至少在內部。如果你進入項目的屬性，在Build - > Qt下，應該有用於各種Qt模塊的複選框，包括'QtOpenGL'。 – Kitsune 2012-02-13 14:02:42

非常感謝，現在正在工作） – test1604 2012-02-13 14:06:27
