So I'm trying to install QtLocation.
I created the qt5vars.cmd in C:\QT exactly with the text stated.
This is my error:
C:\QT\QT5>REM Set up \Microsoft Visual Studio 2013, where <arch> is \c
amd64, \c x86, etc.
The syntax of the command is incorrect.
C:\QT\QT5>CALL "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\
vcvarsall.bat" <arch>
C:\QT\QT5>configure -debug -nomake examples -opensource
'configure' is not recognized as an internal or external command,
operable program or batch file.
C:\QT\QT5>
Can anyone point me to the problem? I just installed Microsoft Visual studio and it is located in
C:\Program Files (x86)\Microsoft Visual Studio 12.0
Edit: Found out that the problem was that I needed to add x86, besides only the complete backage consists of the make and configure so therefor I downloaded the complete package.
Now I have a new error

I had the same problem. I found the answer here Build Qt 5.4 in windows: use VS2010 and here Unresolved external symbol attempting to build 5.2.
To solve this problem:
Check the file QT_HOME\qtdeclarative\src\qml\RegExpJitTables.h is empty or not. If it is empty, delete it. (In later versions the file is situated in each of the subdirectories of QT_HOME\qtdeclarative\src\qml\.generated\ directory.)
make sure that python is in your PATH
nmake
It works for me.

I was working on a QT program including libtorch and opencv which was compiling without any error in my previous Ubuntu 21.04.
The libtorch library locates at /home/user/Downloads/libtorch and OpenCV installed with the following command:
apt install python3-opencv libopencv-dev libdc1394-22-dev
After upgrading my OS to Ubuntu jammy (22.04), building that program returns the following errors:

Obviously it means that it has unresolved symbols which I couldn't understand what symbols they are.
I have a very strange problem I create an application that use QNetworkAcessManager to download an HTML page and get the data from this page I release my application to use it on my second laptop on the same wireless connection but it not works.
on my computer, after releasing the app and use windeploy.exe to get all the dll file for this release exe I try to use it on my computer which has QT and developed on it it works fine and get the data in the file.
the problem comes when I use it on another computer the app works but when I press the button to get the data it gets nothing just empty file
so any help for this problem
this the code which I use normal QNetworkAcessManager code to get HTML page data
this code in the button to get the data
manager->clearAccessCache();
manager->clearConnectionCache();
if (reply != nullptr)
delete reply;
reply = manager->get(QNetworkRequest(QUrl("https://normalpage.html")));
connect(reply, SIGNAL(readyRead()), this, SLOT(readyRead()));
connect(reply, SIGNAL(finished()), this, SLOT(Finish()));
readyread
void MainWindow::readyRead()
{
data.append(reply->readAll());
}
finish function I get the data of type QByteArray and use it to get the data from it the function is long
I was having this problem for about two months but I was in hurry so I used libcurl with QProcess to get this HTML page data but I now I want to know what cause this problem
update
I used the code in my main.cpp to get all the Qt warnings and errors in a file as mention in the comment by Macias and I get this into the file I used append to the file so I can get all the error it comes and I got some warnings from QSslSocket if anyone can check these warnings and see if it cause the problem as I don't know

connect the reply to the error signal

and the slot is here

this what i get after connect error signal and the attribute

when I added the three dlls file to the release folder on my computer which the app i working without them i got this error
when i go to the path of C:\AppServ\Apache24\bin and copied this dlls (libeay32.dll and ssleay32.dll) from this folder instead of the others i downloaded from the dll website it finally it works but what is the difference between both in the appchace folder and that are download from website?
thanks in advance
Make sure that you have libeay32.dll, libssl32.dll and ssleay32.dll libs in your deployment folder. If not just copy them next to your *.exe
windeployqt tool does not include these libs.
EDIT:
Your error is propably caused by incopatible version of openSSL library.
Version in use at compile time is different from this used at run-time. You can easily check it out. Add these lines after QApplication creation in main.cpp:
qDebug() << "SslSupport: " << QSslSocket::supportsSsl();
qDebug() << "SslLibraryBuildVersion: " << QSslSocket::sslLibraryBuildVersionString();
qDebug() << "SslLibraryRuntimeVersion: " << QSslSocket::sslLibraryVersionString();
You should install and put to your release the most similar to build version.
I'm trying to get the Leptonica 1.68 to work with Qt 5.2.0 (vs2012) static libraries. So i decided to try out the static libraries first, i downloaded the following package leptonica-1.68-win32-lib-include-dirs.zip
And iclude it in my project like so:
LIBS += -L$$PWD\leptonica-1.68-win32-lib-include-dirs\lib -lliblept168-static-mtdll -lgiflib416-static-mtdll
I also use the opencv that i build myself using vc2012+cmake
LIBS += -L$$PWD\opencv\static_libs -llibjpegd -llibpngd -llibtiffd -lIlmImfd -llibjasperd -lopencv_calib3d246d -lopencv_contrib246d -lopencv_core246d -lopencv_features2d246d -lopencv_flann246d -lopencv_gpu246d -lopencv_highgui246d -lopencv_imgproc246d -lopencv_legacy246d -lopencv_ml246d -lopencv_nonfree246d -lopencv_objdetect246d -lopencv_photo246d -lopencv_stitching246d -lopencv_superres246d -lopencv_ts246d -lzlibd
Opencv is built with /MTd and leptonica is built with /MTd too (i assume it from the library name "static-mtdll")
My qt is built with the following configuration:
configure -static -debug-and-release -opensource -confirm-license -platform win
32-msvc2012 -mp -qt-sql-sqlite -plugin-sql-mysql -I C:\MYSQL\include -L C:\QT\lib -c++11 -no-opengl
-nomake tests -nomake examples -no-crt -qt-zlib -qt-libpng -qt-libjpeg
When i'm trying to build my application i get

I tried to add /NODEFAULTLIBRARY:MSVCRT.LIB to my pro file but LIBCMTD errors still remain, and i get more warnings like this:

If i build that project dynamically using non-static qt version and opencv non-static libraries everything works just fine. (i guess that would be /MD). So i assume that leptonica is compiled with /MD and i need to recomplie it with /MTd (static debug). Please help, or maybe provide a faq or solution for building leptonica using vc2012.
I created a simple GUI application in QtCreator (QT 4.8.2) and added a function to check the network connectivity:
bool MainWindow::CheckNetworkConnectivity()
{
QList<QNetworkInterface> interface = QNetworkInterface::allInterfaces();
for(int i = 0; i < interface.count();i++)
{
QNetworkInterface inface = interface.at(i);
if(inface.IsUp && !inface.IsLoopBack)
{
ui->lstLog->addItem(inface.name()+QDateTime::currentDateTime().toString("h:m:s ap"));
ui->chkConStatus->setChecked(true);
}
else{
ui->chkConStatus->setChecked(false);
}
}
return ui->chkConStatus->checkState();
}
After that any attempts to compile the code generates the following errors:

Error while building/deploying project MasterVPN (target: Desktop)
When executing step 'Make'
Can someone please point out what the cause could be?
The linker is indicating that is can not find the required functionality. This is contained within QtNetwork4.lib (if you're on a Windows platform) or the equivalent library for your platform. So you have to tell the linker that it needs to link against this library. The network module is the required one, so instead of just
QT += core gui
at least make that
QT += core gui network
That should fix the linker errors you see.
I tried to compile Qt+Webkit statically with MS VS 2008 and this worked.

Do I need to check something in the Qt project options? I have QtCore, QtGui, Network and WebKit checked.
It looks like you need to link in the windows .lib files for each of the missing functions:
VerQueryValue,GetFileVersionInfo -> version.lib
GetFileVersionInfoSize -> Coredll.lib
PathRemoveFileSpec, SHGetValue, PathCombine -> shlwapi.lib
If you are using qmake, you add:
LIBS += -lversion -lCoredll -lshlwapi
Otherwise: From the Project menu, choose Properties. Open Configuration Properties->Linker->Input. In the Additional Dependencies field, add version.lib, Coredll.lib and shlwapi.lib
