-mfpu= Argument not recognised

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

gcc (Debian 10.2.1-6) 10.2.1 20210110

Not too old. That's strange because -mfpu is still documented : https://gcc.gnu.org/onlinedocs/gcc-10.4.0/gcc/ARM-Options.html#ARM-Options

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

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