c++ - MXE Qt5 应用程序在 Docker 容器中构建失败

Question

所以，我已经在 Docker 容器(基于 Ubuntu 18.04)中成功构建了 MXE 和 Qt5 (make qt5)，并将内容复制到 /opt/mxe 中，附加 PATH 和 /opt/mxe/usr/bin。

但是，当我尝试在容器内构建 Qt5 应用程序时，qmake 和 CMake 都失败了。由于某种原因，Qt 工具无法正常工作。这是 qmake 的输出:

# i686-w64-mingw32.static-qmake-qt5 ../heimer.pro

资源编译器找不到任何东西。

CMake 构建失败，如下所示:

让我们检查容器内的 Qt 配置:

看起来没问题。

当然，无论是否使用 MXE，以及使用 qmake 和 CMake，我的应用程序都可以在我的主机上完美编译。

有什么想法吗？

使用 --privileged 运行 docker 容器解决了该问题。
