Can't add HDF5 library in empty Qt-project

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 :)

Please_Help_me_D

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 ?

@SGaist Now I wrote:

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

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
