How to run SoftFloat based binary in OrangePiPC ?

 

I have flashed my OrangePiPC with "Armbian_20.08.1_Orangepipc_buster_current_5.8.5.img.xz".

When I cross compiled my C based application with ARM hard-float toolchain "gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabihf", Its compiled in my linux pc and able to run that application in OrangePiPC. Its working fine.

But When I cross compiled my C based application with ARM Soft-float toolchain "gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabi" (with -mfloat-abi=softfp), Its compiled and Couldn't able to run that application in OrangePiPC.
It showing error like "No such file".

Could you please let me know how to run Soft-float based my application binary in OrangePiPC board?

Try cross-compiling with -mfloat-abi=soft -static, all libraries on your armbian image are armhf:

 

% dpkg -S libm.so
libc6:armhf: /lib/arm-linux-gnueabihf/libm.so.6
libc6-dev:armhf: /usr/lib/arm-linux-gnueabihf/libm.so
