Generic warning obscures CLI programs

[mcandre]

Specs:

Mac OS X 10.6.5
MacPorts 1.9.2
CLISP 2.49
Quicklisp beta

I like to make command line scripts in Common Lisp. I find that generic warnings that don't apply to me or the users of my scripts just get in the way, obscuring the command line interface. This warning appears when I load ASDF:

WARNING: No architecture feature found in

     ((AMD64 X86-64 X86_64 X8664-TARGET)
     (X86 I386 I486 I586 I686 PENTIUM3 PENTIUM4 PC386 IAPX386
     X8632-TARGET) HPPA64
     HPPA (PPC64 PPC64-TARGET) (PPC32 PPC32-TARGET PPC POWERPC) SPARC64
     (SPARC32 SPARC) (ARM ARM-TARGET) (JAVA JAVA-1.4 JAVA-1.5 JAVA-1.6
     JAVA-1.7)).

I looked in asdf.lisp and found the relevant code: lines 2576-2578:

      (arch (maybe-warn (first-feature *architecture-features*)
                        "No architecture feature found in ~a."
                        *architecture-features*))

This appears to ask CLISP for architecture-features, which it doesn't support, then informs the user of this. I don't need to be reminded every time I load ASDF, and the users of my CLISP scripts don't need to be reminded, either.

Could ASDF omit this warning in future versions?

What is your *features* ?

[Robert P. Goldman (rpgoldman)]

I'm not sure that this is actually really the bug you think it is.

As I understand things, what's going on here is that ASDF is trying to compose for you an implementation-specific relative location component.

I don't believe that the bug is the warning. The bug is actually that we try to find the architecture for clisp.

I think the right solution is to modify implementation-identifier so that when we're running CLISP we just bind ARCH to NIL and don't even call the maybe-warn.

I can propose a patch, but don't run CLISP, so I can't easily test it.

[Faré (fahree)]

I think the correct solution is to analyze your *features* and make ASDF able to extract a proper feature from it.

In the meantime, you can change the (maybe-warn ...) form to:
(or (first-feature *architecture-features*) "unknown")

OK, should be fixed in 2.011.4. Please test.

I'm using ASDF through Quicklisp, will test in the next Quicklisp rev. And thanks very much!
