Qt/C++ with Microsoft C++ - C1190: managed targeted code requires a '/clr' option

[Ibrahim]

Hi; I compiled managed code with Microsoft C++ compiler in Qt Creator but I get this error message: error: C1190: managed targeted code requires a '/clr' option
How can I set this /clr option in Qt Creator? Should I put this option .pro file?
Thanks.

in the .pro file add the line

QMAKE_CXXFLAGS += -clr

you'll probably also need:

QMAKE_CXXFLAGS_STL_ON -= -EHsc
QMAKE_CXXFLAGS_EXCEPTIONS_ON -= -EHsc

@VRonin Thanks, but these are not running. I get still same error.

[VRonin]

Clean and rebuild. Qt Creator is very bad at detecting changes in the .pro file

[Ibrahim]

@VRonin I tried but it is not running. I created a new Qt Console Project and wrote this example code:

#include <QCoreApplication>

int main(int argc, char *argv[])
{
  QCoreApplication a(argc, argv);

  int x = 17;
  int^ n = &x;

  return a.exec();
}

but I get this error: error: C3193: '^': requires '/clr' or '/ZW' command line option

[VRonin]

could you try and download all the files (apart for the vcxproj and vcxproj.filters) from here https://github.com/VSRonin/FXhelper/tree/master/ManagedProcess and try to compile?

@VRonin I tried with MSVC2015, WinRT arm and Windows Runtime 32 bit, I get this warning: Project WARNING: Prefix not set, install will not work
But When I compiled project I saw empty console screen.

[VRonin]

yes, that warning is hard coded in the pro file, you can ignore it.
Since that project compiles you can use it as base. Remove my cpp and h files, add yours and compile.

To get rid of the warning remove the section

isEmpty(PREFIX){
	warning("Prefix not set, install will not work")
}
else{
    target.path = "$$PREFIX"
    INSTALLS += target
}

in the pro file

@VRonin I put this code in the main.cpp file: Console::WriteLine("Hello World!");
But I see empty black console screen.

[VRonin]

did you change the .pri file to include such main.cpp file?
