Can't add HDF5 library in empty Qt-project

Please_Help_me_D

@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 ?

Please_Help_me_D

@SGaist As far as I see yes. I marked it with bold style.
The compilator output uses backslashes () and I use slash (/) when pointing a directory. In Windows 7 slashes worked normally, couldn't that be a reason in Windows 10?

SGaist

That's surprising... the slash/backslash conversion should be handled automatically for you.

What happens if you uses backslashes in your .pro file ?

Please_Help_me_D

@SGaist Now I wrote:

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

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

and I get the same error:

Both variants are possible? That is useful because I always forget the way I should use slash or backslash :)

SGaist

Well, by default use forward slashes. Qt does the conversion and you even have specific functions in QDir for converting if you need the native version.

Can you show the exact path where the header is located including the file name ?

Please_Help_me_D

@SGaist ok
i write from my phone now but it is here:
C:/apps/MSVC_debug/HDF5_1106/lib/libhdf5_D.lib
C:/apps/MSVC_debug/HDF5_1106/include

I probably mistaken a little but there is no spaces in path.
A little bit later i can copy the correct path

Please_Help_me_D

@SGaist On SSD disk include directory that contains "hdf5.h" is in:
C:\apps\MSVC_apps_debug\HDF5_1106\include\hdf5.h

And on HDD disk (that used to be the C:\ folder when I had Windows 7):
E:\apps\MSVC_apps_debug\HDF5_NO_MPI\include\hdf5.h

SGaist

Might be a silly question but do you have proper read access to these folders ?

One other thing to try, create a new default project and just put the minimal needed to use hdf5.

Please_Help_me_D

@SGaist yes I have permission. And yesterday I've tried to create new project and copy the content to it but it did't solve the problem.

Few minuts ago I just tried the following. I have two QtCreator: one is standart that comes with Qt (compiled with MSVC 32 C:\Qt\Tools\QtCreator) and other I installed to the folder C:\Qt\Tools\qtcreator-4.11.0 that is compiled with MSVC 64. Yesterday I was trying to use the one that compiled with MSVC 64. But now I tried to use standart QtCreator x32 and it runs the apllication without problem. After that I launched QtCreator x64 and it runs too.

I don't know why this happened but I think there is two possible reasons:

I always used wrong path to the library and include directory (I checked it many times but still such things sometimes happen)
something that is connected with the build type of QtCreator x32 or x64 (or how they were installed or kits). Both of them of version 4.11.0

SGaist

What I meant was to not use anything from your other project so you would have something completely independent.

As for Qt Creator, its architecture has nothing to do with the architecture of the Qt version you are using.

Anyway, glad you have it working now !

Please_Help_me_D

@SGaist Thank you for the time you spent!
