Hello,

2 or 3 weeks ago i compiled qmllive and it was working correctly. https://github.com/qtproject/qt-apps-qmllive/tree/5.13

Today i tryed to run it, but got error "Qt5Core.dll is missing" ..,
i deleted everything in the build directory and try to rebuild

now I use Qt5.13.0 / mingw73_64, i'm able to build qmllive from command line :

git clone http://code.qt.io/qt-apps/qmllive.git
cd qt-apps-qmllive
git checkout -b 5.13 origin/5.13
mkdir build && cd build
qmake..
mingw32-make install

but get error when i try to run the executable :
Entry Point _ZdaPvy Not Found not found in libstdc++-6.dll

Does someone have an idea on what the problem is please ?

@LeLev Do you have more than one MinGW installation on your system?

@jsulm hi,
yes i have more than one minGW but i use :

qmake.exe in \Qt\5.13.0\mingw73_64\bin
and
mingw32-make in \Qt\Tools\mingw730_64\bin

jsulm

@LeLev The problem is probably that when you start your app the system loads libstdc++ from the wrong MinGW. Did you add that other MinGW to your PATH?

@jsulm i only have this 2 in my PATH
C:\Qt\5.13.0\mingw73_64\bin;
C:\Qt\Tools\mingw730_64\bin;

jsulm

@LeLev Use Dependency Walker tool to check which libs are used

@jsulm thank you
indeed it looks like you are right : it is using libstdc++ from my gstreamer install dir...
Could you please tell me how to force right libs to be used ?

@LeLev said in qt-apps-qmllive:

@jsulm i only have this 2 in my PATH
C:\Qt\5.13.0\mingw73_64\bin;
C:\Qt\Tools\mingw730_64\bin;

i have this in my PATH > C:\gstreamer\1.0\x86_64\

@LeLev You could deploy the app https://doc.qt.io/qt-5/windows-deployment.html
Or as temporary solution set PATH before calling your app in a batch script. Add the correct MinGW directory at the beginning of your PATH.

@jsulm thank you so much
