Static Builds not Working

ed-wright · 21 Jun 2018, 14:45

@raven-worx Thanks for your reply

If I uncomment the line CONFIG += static, should this make my project statically compiled?
Is this a download or do i have to build this. I have a Qt Commercial licence.
So if i want to statically link QNetwork for example do add QTPLUGIN += qnetwork (i am reading the link you sent as we speak)

@mrjj Thanks again for your reply, I do have a commercial licence but i happy to stay on here if it helps someone else in the future.
What is the process for statically linking Qt into my project?

What I ultimately want is a stand-alone application (just an .exe) that i can run to start my application no DLLs

Hi
Then you have to build a static Qt version.
I have seen static pre-build for Qt Device Creation but im not sure
if they have one for Desktop. (I would ask, it takes quite some time to compile
a full Qt unless your pc is epic)
this is a good start read
https://wiki.qt.io/Build_Standalone_Qt_Application_for_Windows
and also
http://amin-ahmadi.com/2016/09/22/how-to-build-qt-5-7-statically-using-msvc14-microsoft-visual-studio-2015/
but first start with
http://doc.qt.io/qt-5/build-sources.html
and make sure you install all it mentions from
http://doc.qt.io/qt-5/windows-requirements.html
perl, and also python i recall. This is a must do or
it will compile for long time and then fail.
Also, use a good pc. Dual core 1.5 ghz slim laptop will take ages.

Back to your original comment, I manually moved over all the Qt5*.dll from C:\QT\Qt5.10.1\5.10.1\msvc2015_64\bin and then ran windeployqt.exe it now executes.

Changes
It is now the release version
My pro is now changed to uncomment the line "#CONFIG += static"
My C:/QT folder is not currently called this as per your recommendation

@ed-wright
Ok, so you successfully made a deployment folder.
Good work. Its also handy to have to check out stuff.

But its not static as that is some more work before thats possible,

I have gone into my Qt account and started downloading qt-everywhere-src-5.10.1.zip, i hope this is the correct download for the static build of Qt. Its Description is, Qt Source Package, Full Framework with Windows style line endings.

mrjj · 21 Jun 2018, 15:14

@ed-wright
Yes, that is the source code. But there is also Qt 5.11
but i assume you been using 5.10.1 ? ( its perfectly fine)
You will then compile a static version from it.
Make sure to reads docs carefully as else it fails and you been wasting hours looking at it compiling.

@mrjj
As im currently using Qt5.10.1 on Qt Creator so i thought i would stick to the same version.

@ed-wright
That is fine. Not an issue. just wanted to be clear up front as the
compiling time is not trivial .)

I have been trying to compile the static version of Qt now and have run into a few issues.
Following http://doc.qt.io/qt-5/windows-building.html to try to build the
static version of Qt.

STEP 1
As i use Qt Creator and i have put the License into the prompt this step is
done

STEP 2
I already have a directory called C:\QT\Qt5.10.1, but from the downloads page
in my account i also have downloaded (Qt Source Package, Full Framework with
Windows style line endings ) and it is unpacked and located at C:\QT\qt-
everywhere-src-5.10.1, my project is currently using the first path.

STEP 3
With the environment variables, in my PATH i have
C:\QT\vs2015\qt5.6.1-64\5.6\msvc2015_64\bin, i do not think this is correct as
i want to be using 5.10.1 with msvs2015 so i think it needs to be.
C:\QT\Qt5.10.1\5.10.1\msvc2015_64\bin is this correct?

Anyway, following the guide my file qt5vars.cmd has the following:

REM Set up \Microsoft Visual Studio 14, where <arch> is \c amd64, \c
x86, etc.
CALL "C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\vcvarsall.bat" amd64
SET _ROOT=C:\QT\qt-everywhere-src-5.10.1
SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%
REM Uncomment the below line when using a git checkout of the source
repository
REM SET PATH=%_ROOT%\qtrepotools\bin;%PATH%
SET _ROOT=

NOTE: i am trying to use the downloaded (Qt Source Package, Full Framework
with Windows style line endings) not the normal 5.10.1 build.

NOTE2: This produces the following when running in the cmd off the shortcut on
the desktop:

C:\WINDOWS>REM Set up \Microsoft Visual Studio 14, where <arch> is \c
amd64, \c
x86, etc.

C:\WINDOWS>CALL "C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\vcvarsal
l.bat" amd64

STEP 4

Using the Developer Command Prompt for VS2015 i navigate to C:\QT\qt-
everywhere-src-5.10.1

and run the following configure -debug -nomake examples -nomake tests -skip
qtwebengine -opensource

i get the following errors

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual
Studio 14.0
\VC\BIN\cl.EXE"' : return code '0x2'

@mrjj

Okay an update, Still not working but got a little further.

I have added the line:
set CL=/I"C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt"

to the file, C:\QT\qt-everywhere-src-5.10.1\configure.bat

it now progresses further BUT now i get this error:

LINK : fatal error LNK1104: cannot open file 'libucrt.lib'
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\link.EXE"' : return code '0x450'
Stop.

im trying to find libucrt.lib as we speak

Hi
Good work.
I have not seen that one before, but it seems to be related to static linking

@mrjj

Adding the following to my configure.bat located in the C:\QT\qt-everywhere-src-5.10.1 directory allowed me to overcome this problem.

set INCLUDE=%INCLUDE%;C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt
set LIB=%LIB%;C:\Program Files (x86)\Windows Kits\10\lib\10.0.10240.0\ucrt\x86

Onto the next issue now.

I have successfully run the command

configure -debug -nomake examples -nomake tests -skip qtwebengine -opensource -static

The next part of the guide states that the following command should be run.

nmake

Once running it went for a few minutes and then produced the following error

This is omitting some of the previous command line output that all worked correctly, this is where it crashed.

Do you have any idea?

So part of the problem was that my default prefix for the configure command was incorrect.

So going back and running the following worked.

configure -debug -nomake examples -nomake tests -skip qtwebengine -opensource -static -prefix C:\QT\qt-everywhere-src-5.10.1 -redo -recheck-all

Then to Build

nmake

Super good work.
Thanks for updating on the way. will be helpful for others.
