qmake not finding right mkspec

ocgltd

I am trying to use the qmake that I just compiled from opensource. I compiled on a RH9 host, building it for arm64 so that I could cross compile for Raspberry. My pwd was /raspi/build when I ran the following configure:

../qt-everywhere-src-6.5.0/configure -release -no-opengl -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=/root/raspi/arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi/bin/arm-none-eabi- -sysroot /raspi/sysroot -opensource -confirm-license -skip qtwayland -skip qtlocation -skip qtscript -make libs -prefix /raspi/qt6 -no-use-gold-linker -no-gbm

which should have placed the compiled code into /raspi/qt6/bin/qmake. So now when I create the makefile for my test program using /raspi/qt6/bin/qmake is get this error:

Info: creating stash file /tmp/myapp/bin/debug/.qmake.stash

Maybe you forgot to setup the environment?

which makes no sense. The configured with line looks nothing like what I used to configure. So using find command I found another qmake in my build directory so I ran that instead:

Using qmake: /raspi/build/qtbase/bin/qmake
Could not find qmake spec 'devices/linux-rasp-pi3-g++'.
Error processing project file: /project/myapp.pro

So I'm guessing at the right one to use, and asked for the spec info:

../qt6/bin/qmake -query

QT_INSTALL_PREFIX:/raspi/qt6
QT_INSTALL_ARCHDATA:/raspi/qt6

QMAKE_SPEC:devices/linux-rasp-pi3-g++
QMAKE_XSPEC:devices/linux-rasp-pi3-g++

and that looks right. Why is the spec folder not found?

@ocgltd said in qmake not finding right mkspec:

Why is the spec folder not found?

Have you run install target after compiling Qt?
