[[qanda:topic_unsolved]] How to link a gfortran static library?
Hi, I saw this post below:
Re: [SOLVED] Compiling Fortran code with gfortran within a C++ project
I added the @LIBS += -lgfortran@ in my *.pro file, but I still got a lot of linking errors like:
undefined reference to `_gfortran_date_and_time'
undefined reference to `_gfortran_st_write'
undefined reference to `_gfortran_adjustl'
undefined reference to `_gfortran_transfer_integer_write'
I added my static Fortran library by Qt Creator IDE Wizard, and it added these lines in my *.pro file:
unix:!macx: LIBS += -L$$PWD/../test/ -lmylib
INCLUDEPATH += $$PWD/../test
DEPENDPATH += $$PWD/../test
unix:!macx: PRE_TARGETDEPS += $$PWD/../test/libmylib.a
How can I solve it?

[[qanda:topic_unsolved]] Qt maintenance tool crashes with unhandled win32 exception [37360]
Qt maintenance tool crashes with unhandled win32 exception [37360]
Steps to reproduce:
- Start Qt Maintenance Tool
- Click next, and skip
- Choose "Update Components". Now it's retrieving meta information.
At the "Select Components" window, the following updates are checked:
Qt Creator 4.10.0 (installed 4.7.2)
Qt Creator 4.10 CDB Debugger Support (installed 4.7.2)
Python ... License version 2 (installed 1.0.0) - Click next, and then click Update. Now the text "Updating components of Qt" and a progress bar is drawn. One second later, I see "MaintenanceTool.exe has stoppen working" with a debug and close program option.
- Choose Debug. Now "Visual Studio just in time debugger" is opened, with the message "An unhandled win32 exception occurred in Maintenancetool.exe [37360]"
- Choose "yes", so visual studio 2010 is started, then the message "invalid license data". comes up. Click close, and choose "no" at the question if you want to use another debugger. Now the maintenance tool is closed.
Versions:

[[qanda:topic_unsolved]] Why the VS2019 that installed the latest Qt Addin does not have the Qt project template?
I installed the latest VS2019 commnity , and then installed the latest Qt Addin plugin into it. I built the latest Qt5.13.1 with VS2019 , and configured the Qt Addin with the output.
But the VS2019's new project/solution still dones NOT have the qt project template .
There is also a very strange thing : VS2019 loaded a VS2013+Qt5.7 solution into it and build it successfully , then any small change in one .cpp file will lead all the solution to be rebuilt. build operation become rebuild operation.

I'm trying to create a Conan binary package for VS2017 but moving qt binary files from the original install location (after building from source) seems to cause issues. What things do I need to factor in when moving files. What environment values need to considered when doing such a thing?
QT_QPA_GENERIC_PLUGINS and QT_QPA_PLATFORM_PLUGIN_PATH are needed not to fail when loading plugins, but QML doesn't seem to work and theming seems to be not present.

[[qanda:topic_unsolved]] module “QtMultimedia” is not installed
I've installed Qt and Qtcreator on a Raspberry Pi 3 using the normal apt-get install method. Everything seems to work fine except when I try to build the declarative-camera example or other multimedia examples I get an error saying "module "QtMultimedia" is not installed". Then the empty white application window pops up.
I've tried installing and reinstalling all the required packages such as libqt5multimedia5, qtmultimedia5-dev, etc and it just says they are installed with newest version.
Has anyone had success with getting qt multimedia working on raspberry pi?

Hello guys!
I tried to build a static application according to this guide:
https://wiki.qt.io/Build_Standalone_Qt_Application_for_Windows

I used the nmake command from "x64 Native Tools Command Prompt for VS 2017" and used MSVC2017 64bit in my project.
