VirtualKeyboard Error : Illegal Instruction

[Kart]

I have created a cross compiled qmake (5.9.1). I am building the example virtualkeyboard with this qmake and the build is successful. But when i am running the application on the target board, i am getting the following error :

Illegal instruction

I created a default Qt Quick application and ran in my target and it is working fine.
I am not able to understand what the issue is. Any help would be appreciated.

Hi,

Might be a silly question but did you cross-compiled the virtual keyboard module separately ?

[Kart]

@SGaist I did.

[SGaist]

With the exact same Qt version you are using for your application ?

[Kart]

@SGaist Yes I did.

[SGaist]

Can you get a backtrace of that crash ?

@SGaist said in VirtualKeyboard Error : Illegal Instruction:

and also you used the correct toolchain?! Somehow the output of your cross compilation isn't compatible

[Kart]

Yes @raven-worx , I have used the correct tool chain. Can you explain exactly what you meant by compatibility ?

[raven-worx]

@name_qt
compatibility with process instructions ;)
E.g. also make sure you didn't mixup ARM and x86, and also binary compatibility (also of the dependencies used for cross-compiling and which are available at the end on the target system)

@raven-worx I checked with the executables and libraries using file command and everything seems to be perfect.
