qt - 如何在 Windows 7 上构建 Quazip 0.5.1？

Question

我正在尝试在安装了 Qt 5.0.1 32 位 LGPL 的 Windows 7(32 位)上构建 quazip 库(0.5.1 版)。

当我在 Qt-Commandprompt 中运行时:

qmake
mingw32-make

将目录设置为我提取 Quazip 的文件夹(C:\Qt\quazip-0.5.1\quazip)，我得到以下错误日志:

C:\Qt\quazip-0.5.1\quazip>mingw32-make

但是在我的 Zlib 文件夹(C:\Qt\Qt5\5.0.1\Src\qtbase\src\3rdparty\zlib)中，所有列出的文件都已安装。

.

当我试图解决这个问题时，我已经添加到 quazip.pro 和 quazip.pri 中:

INCLUDEPATH += $$[QT_INSTALL_PREFIX]/src/3rdparty/zlib

, 怎么建议 here .

到目前为止，我在 Google 上找到的所有其他解决方案都无济于事。

我希望你们中有人能帮助我。

你好，

问题是 QuaZIP 找不到 zlib 库。当你运行 qmake 时，你应该包括头文件的路径和库:

qmake "INCLUDEPATH+=C:/Qt/Qt5/5.0.1/Src/qtbase/src/3rdparty/zlib" "LIBS+=-LC:/Qt/Qt5/5.0.1/Src/qtbase/src/3rdparty/zlib -lz"
mingw32-make
