@gregoryjithin The only suggestion (besides the correct one from @Pablo-J-Rogina - why don't you ask in correct forum? Your question/problem has no relation to Qt) I have is to do what the error message suggests: you need the OpenSSL libraries. Download them and put them into same directory where wsdl2h.exe is...

Hi @SGaist,

My .png is also transparent expect the border of the image. For my button I have tried setting the button to transparent using setStyleSheet. It is still the same.

Upon further evaluation, the labels are put at the major tick marks, so the real question is how to change the physical spacing of the major tick marks. I'm not displaying the minor tick marks, but it appears that physical space is being allocated for them. I need to eliminate this physical spacing.

Hi,

Your question is not really clear, what exactly do you want to build ? GDAL itself ? An application using both Qt and GDAL ?

Managed to fix this by using:

install_name_tool -change /usr/local/lib/gcc/8/libgcc_s.1.dylib @executable_path/../Frameworks/libgcc_s.1.dylib /Applications/myApp.app/Contents/Frameworks/libgomp.1.dylib

libgomp.1.dylib was originally pointing to an older version of gcc inside /usr/local/lib/gcc

Thanks for your help!

In that case, you should rather contact the library authors to get help building their library.

We do using cmake. Do you use cmake?

Hi,

Yes it is, and IIRC, there's already an implementation of the event dispatcher with Glib.

@filipdns
Have you run your program under the debugger and looked at the traceback when whatever you mean by "app crash" occurs? Are you under Linux with core dumps? That is always by far the best place to start from.

If no core dumps and you can't run under debugger (e.g. it runs unattended overnight), what about putting in extensive but basic logging lines (to file) to see where it's going?

Hi and welcome to devnet,

Did check the solution provided by @hskoglund ?
What trouble do you have ?
Did you check that you have all dependencies needed ?

Thank you for your help!

Hi @MrNickless, welcome!

From your description, the editor problem sounds again like a Clang Code Model problem. You can try to disable it with Help > About Plugins > Clang Code Model.

That however, is completely unrelated to compile or run problems. Did I get it right that you can compile the code and it runs on the target, but has runtime problems? Which kind of problems?

Regards

Hi and welcome to devnet,

Please show the error message you get, your description is not enough.

@VRonin
Hi
I have it installed and running now.
It only appears to run on exes built in release mode - is this expected?

Okay, I got it running thanks to your help, I'll post my solution for the case anybody will run into similar issues:

"main.h":

#include <QtWidgets/QWidget> #include "ui_HwMonTool_app.h" #include "PresentLogic.h" class HwMonTool_app : public QWidget { Q_OBJECT public: HwMonTool_app(QWidget *parent = Q_NULLPTR); private: Ui::HwMonTool_appClass ui; CPresentLogic logic; };

"main.cpp":

#include "HwMonTool_app.h" HwMonTool_app::HwMonTool_app(QWidget *parent) : QWidget(parent) { ui.setupUi(this); // when adding more signal-slot connections, follow this syntax: connect(ui.pushButton, &QPushButton::released, &(this->logic), &CPresentLogic::buttonPressed); }

"PresentationLogic.h":

#include "qobject.h" class CPresentLogic : public QObject { Q_OBJECT public: CPresentLogic() {}; ~CPresentLogic() {}; public slots: void buttonPressed(void) { // put breakpoint here while (0); } };

When running this code in debugger and pressing (releasing) the pushButton, the buttonPressed() slot is called.

Thanks again for all the help, this topic can now be locked :)

@SGaist Thanks for your help. I'm trying to use the same library across platforms. I found a way to compile the openldap library for mac/iOS version using this link https://www.ibm.com/developerworks/aix/library/au-iphoneapp/?ca=drs- . In the same way I'm trying to find the ways for compiling the library with MSVC and GCC so that the code for connecting, authentication and queries will be same on all the platforms. I know this is out Qt scope but trying to find whether someone succeeded in doing it.

You have to check that the request was succesfull xhr.status == 200, probably the server answers you with an error and this is why you are getting xhr.responseText = null.

Inspect if you are getting an http error code in xhr.status and the number to get more info.
