How to make qt to detect embeded device on compiling time?

arsinte_andrei

at the moment I'm playing with a raspberry pi and I have a problem with the Qt Creator when want to run the app on my PC or on Raspberry.

When running the program on pi I have to add

target.path = /home/pi/atpSmartHome
INSTALLS += target

but when I have to run it on PC I have to comment out thowse lines... any way to do comething like

embeded_PI {
         target.path = /home/pi/atpSmartHome
         INSTALLS += target
}

or anithing similar to this?

Many thanks

HI
Im sure its possible but not sure what to check on - when compiling for the ARM

http://stackoverflow.com/questions/24549612/qt-project-file-add-libs-depending-on-kit

I assume you must change the kit to compile to the RB, so maybe the
CONFIG(Desktop, Desktop|Target_ARM) xx can be used.

arsinte_andrei

yes but I'm looking for something like

KIT = Desktop
#KIT = RPI

And use contains function

contains( KIT, Desktop ) {
     LIBS += ...
}
contains( KIT, RPI) {
     target.path = /home/pi/atpSmartHome
INSTALLS += target
}

how to maker qt Creator to detect witch settings to use?

@arsinte_andrei
Ok, does this work then?
You have to "flip" KIT when you change but I guess that is ok?

@arsinte_andrei
It wont auto detect.

You could just check kit name maybe

MY_QT_INSTALL_PREFIX=$$[QT_INSTALL_PREFIX]
equals(MY_QT_INSTALL_PREFIX,"C:/Qt/5.7/mingw53_32"){
message($$[QT_INSTALL_PREFIX])
}

When i change between STATIC and normal kits i can catch it this way.
I assume you can do the same for ARM.

To check it that can work for you

insert
message($$[QT_INSTALL_PREFIX])

in the .pro file and change kits and see what it prints.
You should then easy be able to use equals to know when
its for ARM.

Searching the forum it also seems that

linux-arm-gnueabi-g++ {
...
}

also works for some platforms. So I guess it also depends on the
mkspec actually used on your platform.

arsinte_andrei

yes.. this is what I've been looking for
now is working
here you have the code


MY_QT_INSTALL_PREFIX=$$[QT_INSTALL_PREFIX]
equals(MY_QT_INSTALL_PREFIX,"/home/andrei/raspi/qt5pi"){
message($$[QT_INSTALL_PREFIX])
target.path = /home/pi/myApp
INSTALLS += target
}

many thanks
