我是新手，正在尝试在qt 5.5下使用Quazip。因此，我只是从http://quazip.sourceforge.net/下载项目源并打开了.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，我刚刚在C:\ GnuWin32中为Windows安装了完整的软件包(从此处:http://gnuwin32.sourceforge.net/packages/zlib.htm)。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
但是改变这条线
#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，现在我得到了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)

我尝试添加以下行:
LIBS += -LC:\GnuWin32\lib
但这并不能解决问题。在Qt下使用Quazip是最简单的方法吗？
最佳答案
至
#include <QtZlib/zlib.h>
关于c++ - 在Windows 8.1和Qt Creator下编译quazip，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/32611058/
