c++ - windows 8.1和qt creator下编译quazip

Question

我是新手，正在尝试在 qt 5.5 下使用 Quazip。所以我刚刚从 http://quazip.sourceforge.net/ 下载了项目源代码并打开 .pro 文件。当我尝试构建项目时出现多个错误:

C1083: Cannot open include file: 'zlib.h': No such file or directory

为了避免在 Windows 上构建 zlib，我刚刚在 C:\GnuWin32 中安装了(从这里:http://gnuwin32.sourceforge.net/packages/zlib.htm)完整的 Windows 包。然后我在 .pro 文件中添加了这一行:

INCLUDEPATH += C:\GnuWin32\include

这产生了另一个错误:

Cannot open include file: 'unistd.h': No such file or directory

但是改变这一行

#if 1           /* HAVE_UNISTD_H -- this line is updated by ./configure */

解决了这个问题。

#if HAVE_UNISTD_H

不幸的是，现在我得到 25 个未解析的外部符号，其中一些:

quaadler32.obj:-1: error: LNK2019: unresolved external symbol adler32 referenced in function "public: virtual unsigned int __cdecl QuaAdler32::calculate(class QByteArray const &)" (?calculate@QuaAdler32@@UEAAIAEBVQByteArray@@@Z)

我尝试添加这一行:

LIBS += -LC:\GnuWin32\lib

但这并没有解决问题。在 Qt 下使用 Quazip 最简单的方法是什么？

Answer 1

1. 从 quzip site 下载 quazip 源代码
2. 通过 Qt Creator quazip.pri 打开
3. 替换所有字符串 #include "zlib.h"或 "#include "

到

#include <QtZlib/zlib.h>

1. 构建项目并运行单元测试。
