大理石窗编译

Question

我正试图在Windows 10上编译Marble，使用Mingw和QT5.5。

g++ (i686-posix-dwarf-rev1, Built by MinGW-W64 project) 4.9.2
Copyright (C) 2014 Free Software Foundation, Inc.

我正在跟踪官方的说明。但是，我收到了编译错误：

看起来zlib有一些问题，我试图通过CMake图形用户界面指定zlib的路径(由我自己用明图手工编译)，但是结果是在链接libmarblewidget-qt5.dll时出现了相同的错误。所以..。有人知道我该怎么修吗？

Answer 1

在"MarbleZipReader.h“文件中，更改

struct Q_GUI_EXPORT FileInfo

至

struct MARBLE_EXPORT FileInfo

这对我有效，但不确定它是否完全正确。我想这会在某个阶段被修补。我在使用大理石支行“应用程序/15.12”。

Answer 2

由于@user5792278的回答，这个问题的链接错误可以被解决。但是，您可能会遇到其他链接错误(涉及libz)。在我的例子中，这是Application/15.12 + Qt5.5 + GCC4.9.2的版本

CMakeFiles\marblewidget-qt5.dir/objects.a(MarbleZip.cpp.obj):MarbleZip.cpp:(.text+...)：未定义引用inflateInit2_ ..。

要解决这个问题，一个快速的(虽然不一定是干净的)攻击，就是替换行。

TARGET_LINK_LIBRARIES (${MARBLEWIDGET} astro)

使用

TARGET_LINK_LIBRARIES (${MARBLEWIDGET} astro z)
