OK, then I believe that defining the method for `OPERATE` will give you what you want. You can put that definition in `my-system.asd` below the `defsystem` for "my-system". There's only one problem with that -- if you `load-system` on "my-system" before `my-system.asd` has been loaded (e.g., by `find-system`), then you will lose, because the around method will not have been defined before the first call to `operate`.

No, it's what we want for our system. We want everyone who builds our system to get this behavior reliably.

Are you just using this for yourself? If so, a simple
(let ((asdf:*compile-file-failure-behaviour* :warn)) (asdf:load-system "my system"))will suffice.
Alternatively, you could put something like this in the .asd file:
(defmethod operate :around ((operation load-op) (system (asdf:find- system "my-system"))) (let ((asdf:*compile-file-failure-behaviour* :warn)) (call-next-method)))The above most emphatically *has not been tested*, so it might be wrong.I *think* if the top-level operation you use is load-op, this should work. Alternatively, you might want to replace (operation load-op) with just (operation operation) (and add a (declare (ignorable operation)))Cheers, r

As has been discussed here over the years, asdf:*compile-file-failure- behaviour* is :warn on most platforms, but it is notoriously :error on #+sbcl.

What else can one do that's any better?
Maybe there's a less crude way, like something like an around method that wraps around the compile/load. I'm really just barely a novice user, so I'm sorry this if this is such a naive question. If there's a simple example one could provide or point me to that does this, I'd appreciate it.> Thanks,
