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

g++ (i686-posix-dwarf-rev1, Built by MinGW-W64 project) 4.9.2

我正在遵循官方指示。但是，我收到编译错误：

看起来 zlib 存在一些问题，我试图通过 CMake GUI 指定 zlib 的路径（由我自己使用 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？

在文件“MarbleZipReader.h”中，更改

struct Q_GUI_EXPORT FileInfo

至

struct MARBLE_EXPORT FileInfo

这对我有用，但不确定它是否完全正确。我认为这将在某个阶段进行修补。我正在使用 Marble 分支“Application/15.12”。

感谢@user5792278的回答，问题的链接错误可以解决。但是，您可能会遇到其他链接错误（关于libz）。就我而言，这是版本Application/15.12++ Qt5.5：GCC4.9.2

CMakeFiles\marblewidget-qt5.dir/objects.a(MarbleZip.cpp.obj):MarbleZip.cpp:(.text+[...]): undefined reference to inflateInit2_ [...]

解决此问题的快速（尽管不一定干净）的方法是替换该行

TARGET_LINK_LIBRARIES (${MARBLEWIDGET} astro)

和

TARGET_LINK_LIBRARIES (${MARBLEWIDGET} astro z)

在文件中sources\src\lib\marble\CMakeLists.txt
