How to build Quazip 0.5.1 on Windows 7? - qt

Question

I'm trying to build the quazip libary (version 0.5.1) on Windows 7 (32-bit) with Qt 5.0.1 32-Bit LGPL installed.
When i run in the Qt-Commandprompt:
qmake
mingw32-make
with the directory set to the folder in which I extracted Quazip (C:\Qt\quazip-0.5.1\quazip), I get the following error-log:
C:\Qt\quazip-0.5.1\quazip>mingw32-make

But in my Zlib-Folder (C:\Qt\Qt5\5.0.1\Src\qtbase\src\3rdparty\zlib) are all this listed files installed.
.
As I tried to solve the problem, I have added into the quazip.pro and into the quazip.pri:
INCLUDEPATH += $$[QT_INSTALL_PREFIX]/src/3rdparty/zlib
, how it is suggested here.
All other solutiuons I have found on Google so far aren't helping.
I hope someone of you can help me.

Answer 1

The problem is that QuaZIP can not find the zlib library. You should include the path of the headers an also the libraries when you run qmake:
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
There is a full explanation in my blog if you want to check it out: http://www.antonioborondo.com/2014/10/22/zipping-and-unzipping-files-with-qt/

Answer 2

Here is what worked for me (QuaZip 0.7 on Windows 7 compiled with MSVC13 32 bits):
In the command line type:
SET INCLUDE=<PathToZib\include>;%INCLUDE%
SET LIB=<PathToZib\lib>;%LIB%
qmake PREFIX=<FolderWhereInstallWillPutFiles> LIBS+=<PathToZib\lib>/zdll.lib
nmake
nmake install
everything between <> must be changed to your applicable path
NOTE:
in the LIBS+= part use / instead of \ as folders delimiter

try to make the lib of quazip on windows - look here:
https://www.maefloresta.com/wiki/doku.php?id=quazip_windows
but - try the following command - instead of "make" take "mingw32-make".
