Compiler doesn't recognize QSslCertificate class when using static library

  • Hi everyone
    I want to build Qt 4.8.5 statically and it's done. Now, I config new qmake for Qt creator. But when I compile my application, I get this error
    @error: 'QSslCertificate' has not been declared@
    I'm using a QSslCertificate object in my project. The compiler with new static qmake doesn't recognize this class. I have included
    @#include <QtCore>
    #include <QtGui>
    #include <QtNetwork/QSslCertificate>
    #include <QtNetwork/QSslKey>@

    and no errors found when using shared library (I have both shared and static library in seperated path).

    Any problems with when ./configure parameter when I do build statically:
    ./configure -prefix /usr/local/Trolltech/Qt-4.8.5_static -largefile -static -qt-libjpeg -qt-libpng -qt-libmng -qt-zlib -debug-and-release -phonon -phonon-backend -svg -dbus -script -qt-sql-mysql -multimedia -audio-backend -opengl -stl -glib -xrender -xshape -xcursor -xinput -xrandr -xfixes -xsync -xkb -xmlpatterns -fontconfig -glib -mitshm -sm -pch -nis -cups -gtkstyle -nomake demos -nomake examples -nomake tools
    How can I build statically Qt library with all libraries?
    Please help me!!
    Thank you

    AFAICS, you didn't enable any openssl option when building your static Qt

  • Thanks SGalst for your reply
    I have tried build Qt normally, I mean non-static.

    just ./configure
    make and make install

    After everything is done, I open my project and this shows the same error.
    @error: 'QSslCertificate' has not been declared@
    What do I have to do? rebuild Qt library again with openssl option enable?
    it takes me more than 2 hours :(

  • Does it required openssl installed? Because when I build Qt, the Ubuntu hasn't been installed openssl.

    Yes it does

    Qt doesn't include OpenSSL

  • Hi SGaist
    After install openssl package
    I've re-build Qt4.8.5 no-static
    make install

    but it cannot find "QSslCertificate"

    @error: 'QSslCertificate' has not been declared@

    My project is using this class.
    I'm using Ubuntu 12.10 x64 and QtCreator 2.8.0

  • Hi, I figured out somthing...
    I've installed Qt4.8.5 on Ubuntu 12.10 32bits. It created "qmake-qt4" file located in /usr/bin and QtCreator using this file as Qt Version to compile qt project. When using that My project has no errors. When I config that linked Qt Version to "qmake" file located in /usr/local/Trolltech/Qt4.8.5/bin and compile my project, the errors:
    @error: 'QSslCertificate' has not been declared@
    appear. So, I use "qmake-qt4" as my current Qt Version on Ubuntu 12.10 32 bits.

    Now, I use the same Qt4.8.5 source code library to build on Ubuntu 64bits.
    After done, I cannot found "qmake-qt4" file in /usr/bin. My QtCreator cannot detect Qt Version automatically. So, I have to manually add Qt Version by browsing to "qmake" located in /usr/local/Trolltech/Qt4.8.5/bin and of course,
    @error: 'QSslCertificate' has not been declared@
    appear like on Ubuntu 32 bits.
    I wonder that, the reason either is my gcc 64 bits or Qt library source?
    I can't see the seperate sources for Ubuntu 32 bits and 64 bits. They use the same source code.
    Any ideas?
    Thank you

    When configuring Qt check the log to see if it found openssl. If not add the -I and -L parameters to tell Qt where to find the includes and libs
