Build Qt (static linking) for Visual Studio 2017 32bits - qt

On my Windows 7 SP1 machine I would like to use Qt in Visual Studio and compile Qt projects with Visual Studip with static linking,to be able to share my projects in a single .exe file.
Since there are no precompiled libraries for Visual Studio 2017 32bits (although they exists for x64),i'm going to compile Qt from sources.
Following Qt's documentation,I started by installing Python 2.7.13 and Active-Perl,and adding their installation path to the PATH variable,along with the gnuwin32/bin folder
Then i created a qt5vars.cmd file under C:\Qt,here's his content :
REM Set up \Microsoft Visual Studio 2017, where <arch> is \c amd64, \c x86, etc.
CALL "C:\Program Files\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat" x86
SET _ROOT=C:\Qt\5.9.1
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=
And finally I unzipped Qt sources (downloaded from here to C:\Qt\5.9.1,and jom under C:\Qt\jom
I'm planning to use these commands (after executing qt5vars.cmd) to compile and install Qt :
configure -debug-and-release -opensource -platform win32-msvc2017 -static -nomake examples -nomake tests -prefix C:\Qt-5.9.1
jom -j 2
jom install
I already installed Qt vs tools in VS2017.
Is the procedure correct,or should I change something ? (particularly in the configure command)

Looks good. My only remarks would be:
To remove gnuwin32 path as I don't see a reason why would you need it.
And consider making a shadow build to keep Qt sources unpolluted.
set _SHADOW_DIR="C:\build_static"
set _SOURCE_DIR="C:\SrcQt5.9.1"
...
cd %_SHADOW_DIR%
call %_SOURCE_DIR%\configure ...

Run: "x86 Native Tools Command Prompt for VS 2017"
Or from console
%comspec% /k "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvars32.bat"
Go to your Qt source dir "qt-everywhere-src-5.14.0/"
Run
configure -static -debug-and-release -prefix "f:\Qt\Static\build\5.14\build" -platform win32-msvc -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -qt-freetype -opengl desktop -qt-sqlite -sql-odbc -no-openssl -opensource -confirm-license -make libs -nomake tools -nomake examples -nomake tests -skip qtwebengine
After some hours run
nmake
Wait some hours again and run
nmake install
A lot of post about qtwebengine,ssl i simply disable this.
Hope this post help you save your expensive time.

Qt Quick emulation layer crashed when QtQuick.Controls is imported in QML

My ssd died and I had to reinstall Qt, Im using the same version as before (5.15.2, Qt Creator 6.0.2 and MSVC2019). Described problems appears only while using Static build.
This type (ApplicationWindow) is not supported as a root (Im not 100% sure if it was fine before reinstall)
Invalid property name "title, maximumHeight, maximumWidth, minimumHeight, minimumWidth".
And finally after resolving (Changed from ApplicationWindow to Window, and commented Invalid Properties) these two errors I got: Line 1: Qt Quick emulation layer crashed. I attached a debugger to Qt Creator and it's 0xC0000005 on Editor, Preview and Render.
I tested it in both ways, with latest Qt Creator (installed before making Static kit because it will wipe my Qt directory) and with Qt Creator 6.0.2 (installed after making Static kit).
To compile Static Kit I used this script, but after some problems (jom and jom install did not create any files in QtInstallDir) I just run configure.bat by myself, and then jom and jom install and files were in their place.
The solution can be:
Designing using diffrent kit with Window and then on release change Kit to static, change Window to ApplicationWindow (Im using onClosing from ApplicationWindow).
but it's dirty and I personally do not like it. Is there any other solution?
EDIT: non-static versions are fine (self-compiled and one from MaintenanceTool).
Static configure.bat:
configure.bat -prefix %QTINSTALLDIR% -platform %PLATFORM% -opensource -debug-and-release -confirm-license -opengl dynamic -mp -static -static-runtime -no-shared -qt-libpng -qt-libjpeg -qt-zlib -qt-pcre -no-compile-examples -nomake examples -no-icu -optimize-size -qt-sqlite -openssl-linked OPENSSL_PREFIX=%SSLINSTALLDIR%
Non-static configure.bat:
configure.bat -prefix %QTINSTALLDIR% -platform %PLATFORM% -opensource -debug-and-release -confirm-license -opengl dynamic -mp -no-compile-examples -nomake examples -optimize-size -qt-sqlite
Diffrence:
-static -static-runtime -no-shared -qt-libpng -qt-libjpeg -qt-zlib -qt-pcre -openssl-linked OPENSSL_PREFIX=<location>
Okay, I fixed the Invalid property name .., I dont know what really fixed it but:
I had wrong versions of requirements. I was on latest of Ruby, Python etc.
I installed Submodules one more time using script linked in main post and then installed them one by one by my own hands using qmake then jom clean all then jom install.
Also I found that the Line 1: Qt Quick emulation layer crashed. error appear only when I have QtQuick.Controls <any_version> in imports. Im still trying to fix this.
Fixed. I did this by doing those steps:
In maintenance tool I downloaded Mingw64 and Mingw64 for 5.15.2 and for "Tools".
I did an static mingw build using this powershell script: https://wiki.qt.io/Building_a_static_Qt_for_Windows_using_MinGW
I saw that the script is changing qmake.conf files in mkspecs folder. I ran this MSVC script to make MSVC Static build and after unzipping QtBase I modified qmake.conf in mkspecs/winrt-x64-msvc2019 and in mkspecs/win32-msvc.
QMAKE_LFLAGS += -static
QMAKE_CFLAGS_RELEASE -= -O2
QMAKE_CFLAGS_RELEASE += -Os
DEFINES += QT_STATIC_BUILD
Then the qt setup and qt build command, when build is finished I modified the (THIS TIME IN PREFIX LOCATION / LOCATION WHERE QT STATIC IS INSTALLED) qmake.conf in mkspecs/winrt-x64-msvc2019 and in mkspecs/win32-msvc
CONFIG += static
Run Qt Creator and the Designer is fine.

Qt static application fails to run on deployed system

After successfully building static QT and my application binary on Linux I moved to Windows to try out the same.
..\qt-everywhere-src-5.12.8\configure.bat -opensource -confirm-license -release -static -static-runtime -no-pch -optimize-size -opengl desktop -platform win32-g++ -prefix "C:\Qt\Static" -skip webengine -nomake tools -nomake tests -nomake examples
mingw32-make -j4 && mingw32-make install
My development environment is Windows 10 x64, MinGW 7.3.0, QT 5.12.8 Static (Built with above cmdline). Now my problem with deployment is:
Strangely the binary is running on a fresh copy of Windows 10, but not on Windows 7. More surprisingly I tried to run the binary on Linux Wine, and voila it worked there as well.
Another problem is related to custom font loading, i.e. QFontDatabase::addApplicationFont also fails on Windows static build. Whereas same code works well on Linux static build or Windows dynamic QT linking. I tried Q_INIT_RESOURCE based on some stackoverflow post but that didn't help.
I tried reading several qt wiki articles but nothing has helped so far for both of the above problems.
Edit #1
Here is the font loading code which is failing on static build:
Q_INIT_RESOURCE(qml);
int idFont = QFontDatabase::addApplicationFont(":/fonts/Comfortaa-Bold.ttf");
if (idFont == -1)
{
qDebug() <<"Failed to load font from resource";
....
Edit #2
There is a new hope. I have just tried building a simple widget application and build that statically with same Qt version. Now it works on fresh Windows 7. So I need to figure out why QML application is not working. Do I need to do anything specific for qml modules or plugin during Qt static build?
Edit #3
Fixed Windows 7 execution issue by changing VM settings.
Fixed the font loading issue by rebuilding Qt. This time I used Qt 5.15.0 and command line was:
configure.bat -opensource -confirm-license -prefix "C:\Qt\5.15.0-Static" -release -static -static-runtime -opengl desktop -platform win32-g++ -make libs -qt-libpng -qt-libjpeg -qt-freetype -qt-zlib -nomake tools -nomake examples -nomake tests -skip qttools
The problem was with VirtualBox display driver which by default doesn't support OpenGL. When I turned on the 3D acceleration in VirtualBox settings the Qt Qml static application worked. This also justifies why my statically linked application worked on Windows 10 as those were installed on direct hardware, not on VM, thus was using proper underlying driver and opengl.
So this implies when you use -opengl desktop flag it uses underlying operating system's opengl library and even though mingw links with -lopenglw32 it still depends on system's opengl.

compile qt 5.12.4 with open ssl static fail

I am trying to compile qt with open ssl statically
I could compile openssl using vs2017 after install perl and configuring it
i used nmake and it worked with -no-shared smoothly.
Then i open the openssl folder and have the following
dll->x64->release>
bin
->c_rehash.pl
->libcrypto-1_1-x64.dll
->libcrypto-1_1-x64.pdb
->libssl-1_1-x64.dll
->libssl-1_1-x64.pdb
->openssl.exe
->openssl.pdb
include
openssl
header files
lib ->libcrypto.lib
->libssl.lib
->ossl_static.pdb
- engines-1_1 -> capi.dll
capi.pdb
padlock.dll
padlock.pdb
Then i opened VS command line
and opened Qt 5.12.4 coder
configure -static -openssl-linked -opengl dynamic -nomake tests -nomake examples -I "T:\openssl\dll\x64\release\include" -L "T:\openssl\dll\x64\release\lib" OPENSSL_LIBS="-lUser32 -lAdvapi32 -lGdi32 -lCrypt32"
I get the following:
error feature 'openssl-linked' was enabled but the pre-condition !features.securetransport && libs.openssl' failed

Compiling static Qt for Windows can't open include file

I've been trying to get a static build of Qt 5.7 together so I can start compiling an application statically on Windows, but it's been a bit of a slog. I've got most of the process working - except it is complaining about not being able to include a file now that I can't see any reason for it to complain about.
I have to use MSVC (2015 is what is installed) and nmake because we're including webkit (which is possible with MinGW - and so we can't cross-compile from Linux either).
I've worked through and adapted the following sites (amongst others):
http://amin-ahmadi.com/2016/09/22/how-to-build-qt-5-7-statically-using-msvc14-microsoft-visual-studio-2015/
https://wiki.qt.io/Building_Qt_Desktop_for_Windows_with_MSVC
How do you compile OpenSSL for x64?
My configure command:
configure -debug-and-release -commercial -static -ltcg -accessibility \
-platform win32-msvc2015 -qt-sql-sqlite -qt-sql-sqlite2 \
-plugin-manifests -no-audio-backend -openssl -no-dbus \
-incredibuild-xge -sse2 -qt-style-windows -qt-style-fusion \
-no-native-gestures -qmake \
-I C:\devel\source\openssl\inc64
And right now it's complaining that it can't load "openssl\ssl.h" - except that this is available in C:\devel\source\openssl\inc64\openssl\ssl.h

What are the different platforms for Qt's configure

I'm trying to build Qt on Windows with the following command:
configure -static -opensource -no-webkit -no-qt3support -no-audio-backend -no-exceptions -no-opengl -no-phonon -phonon-backend
and I get this error:
Unable to detect the platform from environment. Use -platform command lineargument
However I don't know what are the different possible values for the "-platform" argument. I tried "win32" and "windows" but none of them are right. I can't find any reference that would list the possible values. Does anybody know what I need to put for Windows 7 (developing with Qt Creator)?
Open mkspecs folder inside qt dir. There you can see multiple folders. Names of this folders are values for -platform switch.
For example, you can use win32-msvc. msvc means using MS visual studio compiler for buiding qt.
Answer found on this topic in russian language.
You should try -platform with those arguments:
win32-g++ (for mingw)
win32-icc (for intel)
win32-msvc (for visual studio)
