我已经开始在 Kubuntu 上使用 QT。我首先通过包管理器安装了 g++。然后我安装了 QT 5.0.1。然后我做了一个测试项目来检查一切是否正确。然后我遇到了以下问题。- 找不到 -lGL - collect2：错误：Id 返回 1 退出状态
我在编译输出中看到
11:32:05: Running steps for project untitled2...
11:32:05: Configuration unchanged, skipping qmake step.

Error while building/deploying project untitled2 (kit: Desktop Qt 5.0.1 GCC 64bit)

请帮我修复这些错误。
