At a guess I'd say that libpvm3.a is referring to "xdr_long",
"listen" etc, and no library has them. You'll need to find
a library that defines them and add a -l flag for it. I think.

Hi! Before raising my questions please point me in the appropriate direction
if these questions have been asked before. I have also just requested to join
the various Haskell mail lists. My questions are really concerned with the
commercial viability of Haskell especially in the face
year ago I had the pleasure of using a compiler (for BETA I think)
where the basic usage for a novice was Just What You Wanted:
% compiler Main.source
From there it figured out which other modules it needed, which
required recompiling, which object files and libraries where needed
While hacking around with MPCs, trying to define a variant of the
Collection class, mutated to suit my own fiendish ends, I ran into
this:
Intervals.hs:345:
Class type variable `e' does not appear in method signature
union2 :: s - s - s
What's the significance of this
There's no description of the multi-parameter type classes extension in the
3.01 user manual; are the extensions implemented as described in the link
below? (I vaguely recollect Simon posting a message on this subject more
recently, but I couldn't find it.)
