Can't add HDF5 library in empty Qt-project

Please_Help_me_D

@Pablo-J-Rogina
That is interesting, thank! Why those path are not equal?
But anyway, I changed those lines to the following:

LIBS += -LC:/apps/MSVC_apps_debug/HDF5/ -lhdf5_cpp_D

INCLUDEPATH += C:/apps/MSVC_apps_debug/HDF5/include
DEPENDPATH += C:/apps/MSVC_apps_debug/HDF5/include

and nothing changed...

@Please_Help_me_D Are you sure the missing symbols are in the lib you added? You should check that and add other libs if needed. Also, you added debug version of the lib: do you build your app in debug or release mode?

Please_Help_me_D

@jsulm How to check the missing symbols are in the or not?
I build debug version of libraries and I try to lauch Qt in debug mod. What is the difference between debug version of libraries and release? Can I build library in debug mod and launch it in Qt in release mod?
Sorry for so many questions but I need to understand the basics of programming in Qt.

Don't know how to do it on Windows, on Linux there is nm tool.
Take a look at https://stackoverflow.com/questions/305287/how-to-see-the-contents-of-windows-library-lib

On Windows you should not mix debug and release binaries. But since you're building in debug mode it should be fine.

Seeing the numbers of .dll files in your bin folder, you shall have the same number of .lib files somewhere. I suspect that you are not linking enough of the hdf5 libraries.

Please_Help_me_D

@jsulm I followed the link you gave and output of dumpbin command:

dumpbin /EXPORTS hdf5_cpp_D.lib

is inside the link (let me know if it works): output_from_dumpbin
I don't know know yet how to read it.

@SGaist I looked to the lib folder and the number of libraries doesn't match to the number of .dll in bin folder. I also tried to add all the libraries:

LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/lhdf5_cpp_D.lib"
LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/lhdf5_D.lib"
LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/hdf5_hl_cpp_D.lib"
LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/hdf5_hl_D.lib"
LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/hdf5_tools_D.lib"

INCLUDEPATH += C:/apps/MSVC_apps_debug/HDF5/include
DEPENDPATH += C:/apps/MSVC_apps_debug/HDF5/include

but the errors don't change

@Please_Help_me_D said in Can't add HDF5 library in empty Qt-project:

LIBS += "-LC:/apps/MSVC_apps_debug/HDF5/lib/lhdf5_D.lib"

This is not a correct syntax. Please try

LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/hdf5_D.lib"

and so on

Please_Help_me_D

@Konstantin-Tokarev I just tried:

LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/lhdf5_cpp_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/lhdf5_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/hdf5_hl_cpp_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/hdf5_hl_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/hdf5_tools_D.lib"

INCLUDEPATH += C:/apps/MSVC_apps_debug/HDF5/include
DEPENDPATH += C:/apps/MSVC_apps_debug/HDF5/include

I get an error:
error: LNK1104: can't open file "C:\apps\MSVC_apps_debug\HDF5\lib\lhdf5_cpp_D.lib"
Does it depend that libraries were built with GUI Cmake and the project I run with qmake?

Konstantin Tokarev

@Please_Help_me_D You have an error in your path: file name is hdf5_cpp_D.lib while you are using lhdf5_cpp_D.lib

Please_Help_me_D

@Konstantin-Tokarev i'm sorry, my mistake. I changed it to the correct name and the errors now are:
main.obj: -1: error: LNK2001: unresolved external character "" public: static class H5 :: FileAccPropList const & const H5 :: FileAccPropList :: DEFAULT "(? DEFAULT @ FileAccPropList @ H5 @@ 2AEBV12 @ EB)"

etc...

Konstantin Tokarev

Make sure that all paths correspond to existing files.Find in which library H5 :: FileAccPropList is defined

Please_Help_me_D

@Konstantin-Tokarev I did

dumpbin /EXPORTS each_of_my_labrary

and I only found that FileAccPropList belongs to hdf5_cpp_D.lib.
One thing seemed to me interesting... When I built HDF5 libraries there was an option to include C++ libraries and I included them. Now output from dumpbin C and C++ libraries are very different. Here are few lines of dumpbin C.lib:

How do you think, maybe C++ libraries were installed incorretly?

@Konstantin-Tokarev @SGaist @jsulm as you suspected the problem was that used wrong libraries. Those libraries whose names begin with lib are static. And those who don't those are shared (information from HDFGroup web-site, see picture).
Previously I tried to include shared libraries and they don't work (don't know why). Now I use static libraries and they work.
So I use the followng lines (it works):

LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/libhdf5_cpp_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/libhdf5_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/libhdf5_hl_cpp_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/libhdf5_hl_D.lib"
LIBS += "C:/apps/MSVC_apps_debug/HDF5/lib/libhdf5_tools_D.lib"

INCLUDEPATH += C:/apps/MSVC_apps_debug/HDF5/include
DEPENDPATH += C:/apps/MSVC_apps_debug/HDF5/include

Can you give me advise why shared libraries don't work? How should I decide whether to use shared or static libraries?

SGaist

So you tried to link to .dll files which are the shared libraries but not what you use to link to on Windows.

.lib files can be either the static version of the libraries or an "import file" used to tell the linker what symbols it will have from the library. The usual way to know which type it is is by looking at its size. Small sizes suggest that you have the import file while bigger sizes suggest static libraries.

Please_Help_me_D

@SGaist thank you for information about the weight of static and shared libraries. One of my shared library weighs 380 kb and the same static library weighs 33 Mb.
I opened them with help of 7zip and I saw that shared .lib-file include .dll files, and static .lib-file includes .obj files (see picture).
Is there a connection between libraries .lib and .exe files and .dll files that are in the bin folder?

SGaist

I was talking about the .lib files themselves.

.dll are in any shared libraries.

I encountered a problem that when I build HDF5 without ZLIB I can run HDF5 library in Qt (as static library for example). But when building HDF5 with ZLIB=on then I can run HDF5 only as dynamic library and still I get error: LNK2001: unresolved external character "H5T_STD_I32BE_g" when I set format for my saving data like integer 32 big endian (or any other data formats). The other functionality works properly (for example I can create empty HDF5-files and add groups in them etc). What maybe the reason of this strange behaviour?
ZLIB, HDF5 builded in DEBUG mode.
If my HDF5 library depends on ZLIB library then in QMake should I add some strings about ZLIB?

Please_Help_me_D

I added ZLIB library to the QMake and it worked :)

To the New Yaer event I got SSD-disk :)
So I decided to install Windows 10 x64 and now I have disk C:\ on SSD and HDD stores all my data from previous installed Windows 7 x64.

I have strange situation... When I run Qt project that uses HDF5 library and this library is on old HDD then I can normally run it.
If I copy HDF5 library to the SSD then I get the following error:
error: C1083: Cannot open include file: 'hdf5.h': No such file or directory

I use:

#include "hdf5.h"

and in .pro file I have:

LIBS += С:/apps/MSVC_apps_debug/HDF5_1106/lib/libhdf5_D.lib \
        С:/apps/MSVC_apps_debug/HDF5_1106/lib/libhdf5_hl_D.lib \
        С:/apps/MSVC_apps_debug/ZLIB/lib/libzlib_D.lib

INCLUDEPATH += С:/apps/MSVC_apps_debug/HDF5_1106/include \
               С:/apps/MSVC_apps_debug/ZLIB/include
DEPENDPATH += С:/apps/MSVC_apps_debug/HDF5_1106/include \
              С:/apps/MSVC_apps_debug/ZLIB/include

By the way it doesn't depend if I recompile HDF5 library with installation folder on C:/ or just copy it from E:/ to C:/ (I mean copy from HDD to SSD). In both cases I get the same error.

Why Qt can't see this header file in include folder?

SGaist

Did you check the build log to see if the paths you added are used ?
