Yes, I did re-run qmake after the changes. I think I will try to make a new project and only import the essentials of the protobuf program to see if that will run.

Hi,

For OpenCV handling please ask the OpenCV forum. This one is about Qt.

There are already numerous threads here that talk about using OpenCV with Qt, please use the search functionality.

Then why not:

LIBS += -LD:/opencv-build/lib \ -lopencv_core320 \ -lopencv_highgui320 \ # etc...

?

@Faisal_Ali

In Qt creator you have a project file with the extension .pro

Check the entries in this file. There typically some entries like

SOURCES += main.cpp\ MainWindow.cpp \ MyRadio.cpp \ MyRadioLine.cpp \ MyLine.cpp HEADERS += MainWindow.h \ MyRadio.h \ MyRadioLine.h \ MyLine.h FORMS += MainWindow.ui

Under SOURCES all files for compilation have to be listed.
Under HEADERS all include files are listed.

Most likely the source file with your source code of structured_light is missing.

If so, the source file is not compiled and cannot be linked to your application.

Yes

AFAIK, Windows doesn't have any system libtiff.

Sorry for zombieing this one.
What that library does is loading all the data from the existing file and re-build it from scratch when you click save this means that any feature that existed in the original file but it's unsupported by the library will be removed on save just because the library doesn't even know they exist

If I comment the lines

SOURCES += main.cpp# \ #$${QUAZIPCODEDIR}/*.cpp \ #$${QUAZIPCODEDIR}/*.c #HEADERS += $${QUAZIPCODEDIR}/*.h

error: undefined reference to `JlCompress::extractDir(QString, QString)'

The QOpenGLFucntionXXX classes only provides your class with access to the OpenGL functions, it's still up to you to mange the context and friends properly.

Hi,

The QtGStreamer module is not part of the Qt project, you should as the author of the module.

Well, I think I have it solved. Not sure what I did differently, but here are the relevant files:

/etc/odbcinst.ini

[MySQL-test] Driver=/usr/local/lib/libmyodbc5a.so Setup=/usr/local/lib/libmyodbc5s.so Description=Connector/ODBC Driver DSN FileUsage=1 UsageCount=1

/etc/odbc.ini

[MySQL-test] Description=MySQL test database Driver=MySQL-test SERVER=127.0.0.1 USER=root PASSWORD=<PASSWORD-GOES-HERE> PORT=3306 DATABASE=test Option=3

Notes:

I created these files using templates with the exact same data in them, and calling "odbcinst -i -s -f odbcinst.template" and "odbcinst -i -f -f odbc.template". I had to put the password to my root account in my odbc.template file. Not sure I like this, but I don't know what the alternative would be. there is nothing in the directory /etc/ODBCDataSources, and I don't have an .odbc.ini file in my home directory. the two pages that helped the most are:
unixodbc
debian
And, it works: mzimmers@debian:/etc$ isql MySQL-test +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+ SQL>

Thanks to everyone who helped...as I said, I'm not sure what I did between the start and the end of this, but it's working now, both with isql and my Qt example.

@SGaist I tried with your suggested link and it works. Thank you so much

Yes totally.. I don't understand why the GUI doesn't appear. There are no build errors or warnings. The project is compiled successfully. I can see the process( .exe) is running in task manager. There is no error. Nothing happens in the window till I stop the debugger.

bg->GetLogger()->Info(...) line works. it actually updates log. I have this line commented for now.
HowToEngineUse() is a function that has series of instructions to advance time and stuff like that.

"I'm wondering if you're not getting stuck in the create of the biogears engine and therefore Qt can't start it's event loop in the main app.exec()." - Do you have any suggestions for debugging?

Hi and welcome to devnet,

What do you mean by "sees to much information" ?

My app gets WMI data and displays it as QTreeWidgetItem, but it consumes to much RAM memory when changing languages.

void MyApp::appOSThread() { try { osWorker = new Worker(); osThread = new QThread(osWorker); osWorker->moveToThread(osThread); connect(osThread, &QThread::started, osWorker, &Worker::appOSWMIData); connect(osWorker, &Worker::appOSData, this, &MyApp::osWMIData); connect(osWorker, &Worker::hardwareDataNotAvailable, this, &MyApp::osWMIDataNotAvailable); connect(osWorker, &Worker::errorNotSupportedOS, this, &MyApp::appNotSupportedOS); connect(osWorker, &Worker::finished, osThread, &QThread::quit, Qt::DirectConnection); connect(osThread, &QThread::destroyed, osThread, &QThread::deleteLater); osThread->start(); logData(QObject::tr("Application: gets OS information")); } catch (...) { QMessageBox::critical(this, QObject::tr("Error"), QObject::tr("An error has occurred with detecting OS!")); } } void MyApp::osWMIData(QStringList property, QStringList data) { int countOSProperties = property.count(); QString osProperty; QString osData; for (int i = 0; i < countOSProperties; i++) { osProperty = property.at(i); osData = data.at(i); osItem = new QTreeWidgetItem(osView); //osView - QTreeWidget osItem->setText(0, osProperty); osItem->setText(1, osData); } } void MyApp::appLocalization() { osView->clear(); appOSThread(); }

For example when app is started takes 30 MB when change language then it takes 3 - 5 MB RAM and when changing again it takes again 5 - 10 MB of RAM.

Any ideas?

Hi,

That's rather a VLC question. You should ask the VLC folks about that behaviour.
