Same problem different compiler -- Need qmake to specify the "-std" flags when invoking g++

Re: [Setting QtCreator compiler build flags when using cmake](gcc on linux -std=c++14)

Hi and welcome to devnet,

What compiler are you using ?
Did you follow the propositions already made on that thread ?

theKid

win32-g++-4.6

I went into the .pro file and added

QMAKE_CXXFLAGS += -std=c++1z

But I still see the same problem where qmake is not generating Makefile with the -std=c++11 or -std=gnu++11

So I am trying to force qmake to specify the "-std" flags when invoking g++

SGaist

How did you install that compiler ?
How did you install Qt ?

theKid

Compiler:
MinGW - Minimalist GNU for Windows
mingw-get-setup.exe

Qt:
qt-opensource-windows-x86-mingw482-4.8.7.exe

@theKid Is there a reason why you're using Qt4?

theKid

Yes, the program I am trying to build requires Qt4 and specficly states that to not use Qt5

SGaist

Why not use the MinGW version that is provided with the Qt installer ?

What reason did they give to not use Qt 5 ?

theKid

I use the QT prompt to compile because otherwise nothing happens when i do a

qmake

I would like to do that but I haven't been able to figure out how to get it done. When I do any kind of qmake outside the Qt prompt.

They give no reason. They just inform you that you are not able to build with Qt 5

SGaist

If you are outside of Qt's prompt you need to either use the full path to the qmake.exe file. Or you have to extend the PATH environment variable to include your build of Qt's bin folder.
