@drmhkelley Use -prefix parameter when you call configure. See http://doc.qt.io/qt-5/configure-options.html

You can compile Qt yourself, see this link. Source code is available from git, or here as zip/ tarball.

same error message

Yes those SQL Server paths are annoying. In my case I've long since removed them. I'm pretty sure that the environment variables are expanded when the command is executed so making that switch won't help in this case.

Then the quick and dirty method would be to comment out the win32 line in qtbase/src/plugins/printsupport/printsupport.pro so the plugin doesn't get built.

How to solve this above errors?

Could you please provide detail information on qt5 build procedure.

Thanks and Regards,
Swathi.

Hey there. I want to build a simple application with some textboxes and dropdowns. Nothing fancy like charts or the like. I did not use QT until now and did not start my project yet as I'm not able to get the "obligations" QT wants. I read though some threads but those did not help me out.

1: Using parts of Qt that are only available under GPL requires open sourcing of your application when distributing
What? I thought LPGL is open source as well. Whats the difference between "GPL open source" and "LGPL open source"?

2: Must provide a relinking mechanism for Qt libraries
How do I provide a "mechanism"? I would assume that it would be enough to link dynamically to the QT librarys. But that would ommit static linking (which seems is only allowed with commercial license anyway). But I understand the "obligation" in the way that I need to provide a possibility for the user to define the name of the library that is getting linked.

3: Must make a Qt source code copy available for customers
As the FAQ states it is not sufficient enough to link to the QT download page. But the download of QT is ~400MB unzipped. But this includes the QTCreator editor. How to ship/provide the Source Code in a reasonable size?
Alternatively you need to provide a written offer with instructions on how to get the source code. Please also note that this has to be under your control, so a link to the source code provided by the Qt Project or Qt Company is not sufficient.
What needs to be under my control? The source code I need to provide or the instructions how to get it.
Is it enough to write: "How to get QT: Google QT download -> Go to download page -> download"?

4: Must make “open” consumer devices
Oh common, what the ... What are they talking about? I don't want to create a dishwasher, I want to write a little program running on windows.

5: The LGPL allows you to keep the source code of your application private as long as it is “work that uses” the library. Dynamic linking is usually recommended here.
I thought it is not allowed to use static linking in LGPL distribution? How would I keep my code private without dynamic linking? If I would link statically, I would need to provide my source so the user can recompile the code, as re-linking with QT library must be possible.

6: The user of your application has to be able to re-link your application against a different or modified version of the Qt library.
Got that above already.
With LGPLv3 it is also explicitly stated that the user needs to be able to run the re-linked binary on it’s intended target device.
Does it mean if "I" target Windows 64Bit and the QT librarys got changed by the user, the program still needs to run on Windows 64Bit? Still the user could change to library to what ever. How should I be able to ensure proper functionality of my program?

I'm slow-witted, but these terms seem not clear at all.

Regards

@azaclauson said in Visual Studio 2017 unresolved external symbol struct QStaticPlugin:

Is there a different mechanism required to link for a Qt static plugin?

Not for linking, no. You should be able to find those libraries in the plugins directory of your build (I think they were in <QtDir>plugins/platforms). You also might need to initialize each of the plugins manually in code as you're linking static:

More info here.

Hi there,

I'm trying to compile Qt5.9.2 with MSVC2017 from source and it won't compile QtWebEngine.

Every other component like QtCore, QtWidgets, QtQuick etc. compiles without any error.

The error QtWebEngine throws is the following:

link /NOLOGO /DYNAMICBASE /NXCOMPAT /DEBUG /DLL /SUBSYSTEM:WINDOWS /VERSION:5.9 /MANIFEST:embed /OUT:..\..\lib\Qt5WebEngineCasd.dll @C:\Users\MIKE~1.KNA\AppData\Local\Temp\nmF02C.tmp

What is wrong and how do I solve this problem?

Hello

I'm trying to use windeployqt.exe. When I run it I get the following errors:

C:\Qt\5.9.1\msvc2015_64\bin\windeployqt.exe C:/Users/dandn/Documents/Qt/build-DeployTest-Desktop_Qt_5_9_1_MSVC2015_64bit-Release/release/DeployTest.exe
Warning: Unable to read C:\Users\dandn\AppData\Local\Continuum\Anaconda3\Library\bin\mkspecs\qconfig.pri: The path was not found.
Unable to find dependent libraries of C:\Users\dandn\AppData\Local\Continuum\Anaconda3\Library\bin\bin\Qt5Widgets.dll :Cannot open 'C:/Users/dandn/AppData/Local/Continuum/Anaconda3/Library/bin/bin/Qt5Widgets.dll': The path was not found.

It is correct that this path does not exist. However I have no idea why it even should look in my python anaconda install folder, instead of the Qt folder with binaries. When i then tried to create the missing folder and copy all dll's to that fodler the error disappered, however then i got an error that it could not find the platform plugin, so I can't get windeployqt running no matter what I try.

Anybody can help me get it working?

static library but still asking for dll
I static compile qtbase and websockets and serialport
add QT += websockets serialport in .pro projact
and static build my project
when run my project
error and request serialport.dll

@parsa

From did you get the source?

AFAIK you still need to download a source version form the archives e.g. for windows the zip and for Linux the tar

Note the source is almost identical, but you cannot simply use the tar on windows and vice versa. The differences are mostly in file endings IIRC.

When you have downloaded and unzipped you will find the configure there.

Hello everyone,

i have a question regarding the generation of additional files with additional compilers.

So my plan is the following:

I have 2 compilers: tao_idl.exe and opendds_idl.exe. These Compilers generate 8 files which i need in my project. Now i want these compilers to be called everytime a person hits build in qt creator. How can i realize that. Additionally the solution must be sharable in the ende, so that other persons working on the project can load a file or something and have the possibility to generate the files as well.

Thank you for your answers.
Kind Regards,
Max

@lqsa

How do you test on development laptop?
Always from creator?

It might be a dumb question, but are you copying also the actual Qt dlls and the Qt plugins?

And of course as soon as I finally give up and post in the forum my build works. Mind you it's been 4 solid days and be my 23rd or 24th attempt...

In the end I think it was a combination of getting the right version of a static openssl build and the OPENSSL_LIBS config parameter set correctly (I also had the OPENSSL_LIBS environment variable set which seemed to conflict with the config parameter).

Below are my steps (you'll need to modify the build paths as required). All builds were performed from the "Visual Studio 2017 x86 Native Tools Command Prompt".

(note needs to be version 1.0.x, Qt does not yet support 1.1.x)

Pay particular attention to the include, library and OPENSSL_LIBS paths in the configure.bat parameters. Getting those right is what eventually got my build working.

Hello,
To answer myself, I found the solution and here is how I did it.

First, I build openssl in static mode. You need to install active perl, mingw-get-setup.exe and mysys-1.0.11.exe (i'm not sure if this one is really required). I downloaded the openssl-1.0.2l sources and I followed this guide: http://www.stringcat.com/company_blog/2015/12/07/compiling-openssl-on-windows-mingw32/
To build, start mingw, go to the openssl root directory and run:

At the end, I created a subdirectory named lib in the openssl dir and copied libssl.a and libcrypo.a into it.

To build Qt, I used this script:
https://sourceforge.net/p/qtlmovie/code/ci/v1.2.16/tree/build/windows-build-qt-static.ps1?format=raw
I added these parameters to the configure line:

In this script, I added a pause between configure and make to be able to modify a file juste before the compilation phase. Just write a new line below configure and write: pause.

Execute the script.

When the script is paused, open the qtbase/mkspecs/qmodule.pri file and change:

to:

and save the file.

Press any key to continue the pause. Wait, enjoy.

I think this is a bug in the Qt build system, in openssl-linked we shouldn't have linked to *eay32...

Hi,

Did you thought of installing it once it was done ?

I have the same error, compiling Qt with angle for MinGW, despite having no E:/ drive on my (virtual) machine (and nothing configured to use it). It's using the same command as yours.

I doubt /E has anything to do with the E:/ drive; and it makes no sense that it claims E:/ as the last path on the command-line (when there is no such entry in the command-line at all). Maybe fxc.exe is invoking something else, with a synthesised command-line, that it's getting wrong. Hard to tell when something that's meant to simply work doesn't :-(

I found that running fxc.exe with /? just got me an error (compilation failed; no code produced) rather than providing the help promised in the error message; this encourages the conjecture that the error actually comes from something else.

There's a matching thread on Stack Overflow, that might be worth watching:
https://stackoverflow.com/posts/46708850/edit

(The Qt Wiki page on building for MS-Win (http://wiki.qt.io/Building_Qt_5_from_Git#Windows_3) stresses that the source and build directory need to be equally deeply nested on the same partition. An odd condition, that I was unwittingly violating; however, conforming to that didn't help.)

Dear SGaist,
I checked;

mucip@debian-ev:~$ openssl version
OpenSSL 1.1.0f 25 May 2017

I followed the below website and install openssl 1.0.0.
https://www.computersnyou.com/3155/update-install-openssl-source-latest-version/

Now the situation is;
mucip@debian-ev:~$ openssl version
OpenSSL 1.0.0s 11 Jun 2015

But I can not update maintenance tool and I can not even run qt-unified-linux-x64-3.0.1-online.run from my computer?!

Where am I wrong?!

Regards,
Mucip:)

@JNBarchan oh thanks, I read this page but I didn't see that, thanks !
So I guess it's OK if I just copy them from my C:\Windows\SysWOW64 folder...
