Problem building quazip-Libary 0.5.1



  • 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.

    Greetings, LVreg



  • 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/
