I applied this patch and can > fix this compilation error. I want you to describe the steps to reproduce the issue from the pristine source tree instead of printing the URL of your origin. I prepared a template for you. Please fill the following 3 square brackets. $ git log --oneline -1 [ Fill the commit hash you are working on ] $ git clean -dfx [ Fill steps between "git clean -dfx" and "make -C samples/bpf" ] $ make -C samples/bpf [ Fill the error message you get ] -- Best Regards Masahiro Yamada
