    I finally found the solution. I had copied the qwt.framework folder to the wrong directory.

    I had copied the qwt.framework folder to the /Users/kelvinsp/Library/Frameworks/ directory and I should have copied to the /System/Library/Frameworks/.

    I just copied the qwt.framework folder to the correct directory ( /System/Library/Frameworks/) and everything ran like a charm.

    Thanks a lot for your help and sorry for waste your time.

    @GiveMeMyName

    I know this topic is kind of old, but I followed the instructions by Kretikus but didn't work. So, I tried to use the link in your post, but it seems it is broken.
    Can you give me some idea of how to solve the issue on your end?

    Here is what I've done so far.

    Even though the build was successful and the dll and lib were generated, there was this error. Do you know why I have the error?

    error: LNK1107: invalid or corrupt file: cannot read at 0x2C0

    I googled it and investigated the issue, and it turned out that the solution file (cryptest.sln) was not correct. I followed the following instructions.
    http://stackoverflow.com/questions/33263734/rebuild-crypto-5-6-2-for-md-release-under-visual-studio-2013
    https://cryptopp.com/wiki/Visual_Studio

    But still I have the following errors.

    mainwindow.obj:-1: error: LNK2001: unresolved external symbol "public: virtual unsigned __int64 __thiscall CryptoPP::ThreadUserTimer::GetCurrentTimerValue(void)" (?GetCurrentTimerValue@ThreadUserTimer@CryptoPP@@UAE_KXZ)

    Is the following code correct?

    INCLUDEPATH += "../extern/msvc2013/cryptopp562/include" LIBS += -L"../extern/msvc2013/cryptopp562/lib" -lcryptopp

    Should I also add dll like this?

    LIBS += -L"../build-user_account_registration-Desktop_Qt_5_6_0_MSVC2013_32bit-Release/release/cryptopp.dll"

    Any help would be appreciated.
    Thank you so much.

    Looks like this is Netbeans thing indeed, as it treats OS output regarding it not being able to start the program the same way.

    Several possibilities for charting in Qt (widgets) are:

    The QtCharts module (still requires a commercial license last time I checked) QCustomPlot (3d party widget), I believe it's under GPL The widgets for technical applications library (Qwt, a set of 3d party widgets).

    This code is hanging by a thread, it works more as a coincidence than anything. As I said LPTSTR is a pointer!

    LPTSTR * name = new LPTSTR [size+1];

    should simply be:

    TCHAR * name = new TCHAR[size + 1];

    And this:

    LPCWSTR newname= reinterpret_cast<LPCWSTR> (name);

    is not needed.

    Hi and welcome to devnet,

    I'd recommend trying to contact the KDSOAP authors. They'll be the more knowledgeable about that matter.

    Hi,

    You should bring this to the QWT folks. They likely be faster to help you with this question.

    Hi,

    IIRC you have to add the DYLD_FRAMEWORK_PATH environment variable to the Run part of the project panel. Copy there the path to then folder containing the qwt.framework bundle.

    Hi,

    The most likely situation: you have either MySQL installed through brew, MacPorts or even from the package on their website and it's not the same version nor the same path than the one used to build Qt.
    Run otool -L on libsqlmysql.dylib to see what's the status.

    It was pretty close:

    unix: CONFIG += link_pkgconfig
    unix: PKGCONFIG += fox

    works nice
