Running the application developed on the Raspberry Pi 4 Ubuntu 18.04.3 lts 64 on the Raspbian Buster 32 bit Compute Module.

Hi everyone.

I've already developed the application on Raspberry Pi4 64 bit 18.04.3 lts. How i run application on the Raspbian Buster 32 bit Compute Module. I've getting error "exec format error".

Hi
im not sure what "Raspbian Buster 32 bit Compute Module" is
but it sounds 32 bit so you must compile your app as 32 bit also to run it there.

So how can I compile it as 32 bit? Compute module is Raspberry Pi embedded systems card.

Well on the pi board where you compile the 64 bit version.
Install the Qt 32 bit packet also
and compile app as 32 bit but selecting the 32 bit kit in "Projects"

Ah, it seems to be like the normal PI so same architecture i would assume
which makes it far easier :)

I can't see the 32-bit kit. So i do not compile.

@Mucahit

Ok. how did you install the 32 bit kit ?

Mucahit

I've installed only 64 bit kit. I don't know how to install 32 bit kit.

Hi
Normally the same way as
you install the 64 bit Qt.

Mucahit

I just want to compile it without installing the app because my memory is so small is it not possible?

@Mucahit
Hi
I dont think you can compile directly on it.
But on the pi board where you compile the 64 version, you can compile a 32 bit version to run on the
Compute module i think.
Seems to be same ARM processor and chipset.

I did it by installing 32 bit qt on another system thank you for everything !!
