Thanks to the above suggestion, as well as the earlier message from Peter Bex, I seem to have gotten the fmt and numbers eggs to work properly together. At least, the earlier errors are gone. In the process, I have probably inserted '(use numbers)' in a few unnecessary places in my copy of the fmt source files. At first I thought I should be able to manage by editing only the compiler flags in fmt.setup (-prelude, etc.), but that didn't work.

Since the fmt egg is compiled without the numbers egg, it only recognizes native Chicken numbers, i.e. fixnums and flonums. The way to fix that is to fetch the fmt egg, introduce "(use numbers)" into the appropriate places, and rebuild the egg locally. > Is this a known limitation of fmt with 'numbers'? It's a limitation of the numbers egg: programs (other than csi itself) have to be compiled with it to work with it. Chicken 5 will make this go away, fortunately. -- John Cowan http://www.ccil.org/~cowanco...@ccil.org Let's face it: software is crap.

I'm afraid so. As far as I know the only way to fix this is to add a hard dependency on numbers to fmt. This may not be desirable depending on what you're using fmt for. This is a result of the second class treatment that extended numbers get, and will be fixed in CHICKEN 5, due to integration of the full numeric tower into core.
