Cmake Configuration for Qt Cross Compilation at Raspberry Zero
-
I need to cross compile lgvl Demo sample ( Beautiful font package based on C++ )into my Raspberry, SO i selected the Qt Creator which i have successfully cross compiled my others project in QT And C++, So i run it via my Linux MINT LMDE via Qt with this Cmake Settings;

SO when i change the kit to raspberry kit i get
Configuration Failederror in cmake build part of project sidebar part of QT Creator as you can see :
and the
build and runbuttons are not active.So why this happened and how could be solved?
Thanks.

@SoheilSabz said in Cmake Configuration for Qt Cross Compilation at Raspberry Zero:
Configuration Failed
Please show the output in "General Messages" tab after running CMake, else we can only guess.

@jsulm For me qmake projects works fine but CMake projects failed because of the following error:
