<rlb>(nb. we may need to figure out the guile-2.2 arch build issues in the next couple of weeks to avoid removal from debian testing.)

<amz3>héllo all

<wingo>happy new year's, guilefolk :)

<amz3>happy new year

<amz3>manumanumanu: how do you bind C++ code in Guile?

<kristofer>I'm on page 60 of the little schemer. my definition of o+ is causing a stack overflow

<kristofer>I thought adjusting (add1 (o+ n (sub1 m))) to (o+ (add1 n) (sub1 m)) in the recursive line might not blow the stack. no luck though.

<kristofer>(o+ n m) where m is 1 or 0 will work. m > 1 will not work though

<kristofer>same is true for (oplus n m)

<ijp>the *definition* is causing an overflow. that's kind of weird

<ijp>ACTION looks

<ijp>or did you mean that it overflows when you call it

<ijp>ah, your sub1 is wrong

<ijp>(- 1 x) = 1 - x, which is an involution, so it's just going to bounce back and forth between x and 1-x

<ijp>(hence why it will terminate for 1 or 0)

<ijp>it's easily done

<kristofer>I knew it had to be user error. 'twas a late night ha

<amz3>ACTION happy
