In order do avoid conflicts between functions, since your first fix I didn’t put the lisp file in the patches folder, but I’ve simply pasted the code replacing the old bpf-extract function in 01-basicproject/functions/functions-lisp. So and pressing “e” I have only one definition, which is the one contained in the bpf-extract2.lisp you gave me yesterday. Maybe I shouldn’t have done so? Moreover, I’m on OM 6.7.
No, you shouldn’t
Modifying the sources a has no effect on the running environment.
Just put the file in the “patches” folder as advised
In fact, that was the issue! Now it works perfectly fine. Many thanks Jean.
