OS: MacOS Big Sur

$ icc --version

This is the oneapi icc version...

When I run 

./configure CC="icc -no-gcc"

or 

./configure CC="icc -gcc-sys"

Checking the C compiler fails with below.  Can you try on Big Sur with latest version here https://www.fftw.org/

Hi,

Thanks for reaching out to us.

We can see that you are trying to configure FFTW using the option "-no-gcc" or "-gcc-sys", could you please let us know if there is any specific reason for that?

We have tried at our end using the below command and we are able to configure it. 

./configure CC="icc" CPPFLAGS=-I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include DFLAGS=-Qoption,cpp,--gnu_version=40805

Could you please let us know if you are still facing any issues?

Thanks & Regards
