我正在尝试使用Mingw和Qt 5.5在Windows 10上编译Marble。

我正在关注官方instruction。但是，我收到编译错误：

似乎zlib出现问题，我试图通过CMake GUI指定zlib的路径（由我自己与Mingw手动编译），但结果是相同的-链接libmarblewidget-qt5.dll时出错。所以...有人知道我该如何解决吗？
最佳答案
在文件“ MarbleZipReader.h”中，更改
struct Q_GUI_EXPORT FileInfo
至
struct MARBLE_EXPORT FileInfo
这对我有用，但不确定是否完全正确。我认为这将在某个阶段进行修补。我正在使用大理石分支“ Application / 15.12”。
