Question

我是新手并试图在qt 5.5下使用Quazip。所以我刚刚从http://quazip.sourceforge.net/下载了项目源并打开了.pro文件。当我尝试构建项目时，我遇到了多个错误：

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

为了避免在Windows上构建zlib，我刚刚安装（从这里：http://gnuwin32.sourceforge.net/packages/zlib.htm）C：\ GnuWin32中的Windows完整包。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

但改变这一行

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

解决这个问题。

#if HAVE_UNISTD_H

不幸的是现在我得到25个未解析的外部符号，其中一些是：

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

但那并没有解决问题。什么是在Qt下使用Quazip最简单的方法？

Answer 1

从quzip site
由Qt Creator quazip.pri打开
替换所有字符串#include＆＃34; zlib.h＆＃34;或＆＃34; #include＆lt; zlib.h＆GT;＆＃34;

到

#include <QtZlib/zlib.h>

构建项目并运行单元测试。

在Windows 8.1和qt creator下编译quazip
