    Default Using HDF5 libraries on QT

    Hi,

    I need to use the format HDF5 for some data we collected (.h5 files). I was trying to install the libraries, but I am having a lot of problems with it. I was searching for it, but I couldn't find any useful information.

    I will appreciate your help!

    Thanks

    Provide more info on those errors you get.

    For the first step, I installed the libraries directly from the ubuntu repositories:

    libhdf5-serial-1.6.6-0 (not this version, the new one)
    libhdf5-serial-dev
    libhdf5-doc
    hdf5-tools

    Then, I try with a simple code on QT, this is:

    #include <iostream>
    using namespace std;

    #include <H5Cpp.h>
    using namespace H5;

    int main(int argc, char *argv[])
    {
    QApplication a(argc, argv);
    MainWindow w;

    H5File fout("data.h5",H5F_ACC_TRUNC);

    w.show();

    return a.exec();
    }

    And I get the following compilation errors:

    I think it is a problem of linking the libraries, but I was searching online and I couldn't find a solution yet...

    Thanks for your help!

    How does your .pro file look like?

    I switched the line in the .pro file

    LIBS += /usr/lib/libhdf5_cpp.so

    for the suggested

    LIBS += /usr/lib/libhdf5_cpp.so -lhdf5

    And at least with the first examples, it is working!

    Thank you very much for you reply and help!! (I will keep on working on this, so if I finally can make it, I will write a small guide for setting up this library)

    You should not need the /usr/lib/libhdf5_cpp.so part of that line.
