Trying to include gtk4 in another environment (openbmc)

I’m trying to run gtk4 in my system to work around in GUI.
But trying to invoke gtk4 binary in yocto, it gives error as mentioned below.
Illegal instruction (core dumped)

Looks like you’re trying to run on your computer a program that was compiled for another architecture, am I right?

  • Run uname -m to get the architecture of your PC, I expect x86_64.
  • Run file ./gtk-example to know the target architecture of your program, will probably be something like arm or aarch64 or mips. But you must see x86_64 too (or maybe i386) to be able to run it on your computer.

You’ll need an emulator like QEMU to test programs of other architectures on your PC. Or alternatively, recompile it manually with an appropriate -march param.

file ./gtk-example
./gtk-example: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/, BuildID[sha1]=e300da957f465688ef7a58771d9379ec7c99174f, for GNU/Linux 3.2.0, stripped
yes, you are right its a arm architecture compiled file

but I’m having uname -m

Yes, exactly, that’s the issue. Both commands must give matching targets, in your case either both “ARM” or both “x86_64”.

You can’t run a ARM binary on a x86_64 system, unless you use an emulator.

could you please suggest that how to build gtk4 from my yocto for arm machine?
any suggestion

I recommend you ask on a Yocto or an OpenBMC support forum.
