[OpenWrt-Users] Confusion on whether the toolchain is for 32-bit ARM or 64-bit ARM

[Ajay Garg]

Hi All.

My development-machine is a x86_64 machine, with Ubuntu-16.04-LTS installed.

Now, I cloned openwrt, selected "Allwinner A1x" as the target, did "make V=s".
Finally, "staging_dir/toolchain-arm_cortex-a8+vfpv3_gcc-7.3.0_musl_eabi/"
toolchain was created.

Thereafter, I compiled a hello-world binary, and it ran successfully
on a beaglebone (ARM) machine.


Now, we wish to use the toolchain for our project, but I am confused
as to whether the toolchain supports (only) 32-bit ARM, or (only)
64-bit ARM, or both 32-bit and 64-bit ARM. So, will be thankful if the
experts can help me on that.

Sorry if the question is too noob.


Looking forward to some help.


Thanks and Regards,
Ajay

Use file cmd in Ubuntu to figure out whether hello-world was compiled for 32-bit or 64-bit.

Ahh.. thanks a ton Naresh !!


Following is what it shows :

#################################
file arm_hello_world
arm_hello_world: ELF 32-bit LSB executable, ARM, EABI5 version 1
(SYSV), statically linked, not stripped
#################################


A follow-up question :
Any openwrt-toolchain supports ONLY either a 32-bit or 64-bit
compilation, depending on the target chosen, right?


Thanks again for the quick help !!


Thanks and Regards,
Ajay

As far as I know, YES. But I might be wrong also.
