gcc compiler options

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier

The documentation recommends to use the following flags:
–mfpu=vfpv4 –mfloat-abi=hard

But when I compile my application on the Jetson Xavier, gcc complains that he does not know these flags:
gcc: error: unrecognized command line option ‘-mfloat-abi=hard’
gcc: error: unrecognized command line option ‘-mfpu=vfpv4’

This is the version of gcc I have:
gcc (Ubuntu/Linaro 7.3.0-27ubuntu1~18.04) 7.3.0

Thanks,

Wrong architecture…those are 32-bit ARMv7/arm32. The Xavier is arm64/aarch64.

You are correct I should have read the documentation more carefully.
Thanks
