C++ HDF5 cannot find -lhdf5d

问题

Situation: I want to create a program to read something from a .hdf5 file.

What i did: Nothing, but adding the hdf5.lib to the project.

Problem:

I get two Errors

when i try to run the program.

cannot find -lhdf5d
error: ld returned 1 exit status

My Code:

HDF5_Test.pro:

TEMPLATE = app
CONFIG += console c++11
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += \
     main.cpp

win32:CONFIG(release, debug|release): LIBS += -L'C:/Program Files/HDF_Group/HDF5/1.10.2/lib/' -lhdf5
else:win32:CONFIG(debug, debug|release): LIBS += -L'C:/Program Files/HDF_Group/HDF5/1.10.2/lib/' -lhdf5d
else:unix: LIBS += -L'C:/Program Files/HDF_Group/HDF5/1.10.2/lib/' -lhdf5

INCLUDEPATH += 'C:/Program Files/HDF_Group/HDF5/1.10.2/include'
DEPENDPATH += 'C:/Program Files/HDF_Group/HDF5/1.10.2/include'

main.cpp:

#define H5_SIZEOF_SSIZE_T H5_SIZEOF_LONG_LONG //this is needed to avoid redefinition conflict of ssize_t (Qt vs HDF5)
#include <hdf5.h>
#include <H5Cpp.h> //Tried with and without this include

int main()
{
    return 0;
}

Using:

C++
Qt 5.10.1
MinGW 32bit
HDF5 1.10.2
Windows 7

In another project for whatever reason these Errors doesn't occur, but these.

回答1:

I linux, using apt-get install libhdf5-dev we get 8 libs installed but none is lihdf5 in its "nature". What i mean by that is that my include would be -lhdf5_openmpi and not-lhdf5. as you didn't provide the download source, try to check if you have multiple libs in your /lib file

回答2:

The Solution was for me to delete the final "d" in this line:

else:win32:CONFIG(debug, debug|release): LIBS += -L'C:/Program Files/HDF_Group/HDF5/1.10.2/lib/' -lhdf5d

Meaning i changed -lhdf5d to -lhdf5.

This problem was fixed this way but lead to another problem.
