Mysql error during compilation

[Rhapsody02]

Hello,
I get following error during compilation (the same on Rpi Zero W and Pi 4B):

"gcc -o database1 chapter5_1.c -I/usr/include/mysql
gcc: error: chapter5_1.c: No such file or directory
gcc: fatal error: no input files
compilation terminated."

Any ideas how to get over this, please?

Found the solution in the chat, following line must be used instead:
git clone https://github.com/matt2005/RoadApplePi

Might be good to update the main page...
