-mfpu= Argument not recognised

[keukenrol]

Hi

I have compiled version 3.7 on my raspberry pi 3b+.
When following the compilation guide in the readme, it states to change the add_compile_options line.
I have done this, but the -mfpu argument was not recognised. I did remove it and it compiled without further issues. Software works as expected.

best regards

Tim

What is your gcc version ?
gcc --version

[keukenrol]

gcc (Debian 10.2.1-6) 10.2.1 20210110

Not too old.
That's strange because -mfpu is still documented :

@keukenrol Are you running a 64 bit OS? I just had the same problem, removed that argument and it worked

[keukenrol]

Yes, as commented I did the same thing to get it working.
