I have tripple checked, and followed the steps for 9.1.0 version first, only then tried 10.1.0 when the 9.1.0 didn't work..

additionally, tried the link you've just provided me with - i have exactly the same error:

pi@bo100nka-pi:~ $ g++-10.1 -std=c++17 -Wall -pedantic if_test.cpp -o if_test

Thanks for checking again. I will try on a fresh Raspbian OS install and let you know.

So I did a complete test, I installed the latest Rasperry Pi OS 32 bits Lite, did an upgrade & update, followed exactly the procedure described in the linked article and now I'm able to build C++ programs with GCC 10.1.

same error here, I tried search those header files, found them under

/usr/include/arm-linux-gnueabihf/sys/

so I copied them to include

sudo cp /usr/include/arm-linux-gnueabihf/sys/* /usr/include/sys/

done

yes, this resolved the problem for me too, thanks a lot
