Problem building quazip-Libary 0.5.1

LVreg

I have problems building 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 output:

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 at http://stackoverflow.com/questions/4449467/how-to-compile-and-use-quazip-on-windows-do-i-need-to-separately-install-zlib

I can't find anything more, what could help me...

I hope someone of you can help me.

I had the same problem:

this is "dirty solution", but it worked for me:

extract quazip somewhere - for example here - C:\Qt\quazip-0.5.1\quazip
download src zlib-1.2.5

extract it somewhere

C:\Qt\zlib-1.2.5

copy all necessary files from zlib-1.2.5 except example.c, CMakeLists.txt...
to C:\Qt\quazip-0.5.1\quazip

and run qmake and mingw32-make...

that's all

a late note to this thread.
I had nearly the same problems with quazip 0.5.1 and Qt5.1 under win7.
My solution is using the command line from Qt and replacing all
#include "zlib.h"
with
#include <QtZlib/zlib.h>

than I could compile quazip dlls separatly and inside my project.

what are those necessary files from zlib-1.2.5?
i can't build quazip on qt5, at windows 8
kinda need help..

I not tink a depend from version of zlib..
To only extract file from zip you can use the class from namenspace
namespace KZip on file:
https://github.com/pehohlva/wv2qt/blob/master/kzip.h
https://github.com/pehohlva/wv2qt/blob/master/kzip.cpp

@
KZip::Stream *unzip = new KZip::Stream(docfilename);
if (debugmodus) {
unzip->explode_todir(this->get_cachedir(), 1);
}
/// or
QMap<QString, QByteArray> all_file = unzip->listData();
// to access on memory all file ...
@

I write this to access docx & odt document.

Hi LVreg,

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/
