Using HDF5 libraries on QT

[breotone]

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:
7282

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?

See Declaring Other Libraries

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.
