[16 of 16] Compiling Main ( src/Main.hs, dist/build/alex/alex-tmp/Main.o )
src/Main.hs:316:25: Ambiguous type variable `e' in the constraint: `GHC.Exception.Exception e' arising from a use of `throw' at src/Main.hs:316:25-31 Probable fix: add a type signature that fixes these type variable(s)
Lines 314 through 316 in src/Main.hs are:
r <- Exception.catch (unblock (thing a)) (\e -> do { after a; throw e })
I guess the error in itself makes some sense, because throw can not be resolved without knowing a concrete instance of e. I just don't get why I get this error in a release version of alex; I would imagine other people do not get this error. What am I missing?
Dear Ian, all, Please ignore my previous e-mail. It must have been a remainder from an earlier failed build attempt. I just did a checkout from the alex darcs repository, which built without a hitch. Regards, Philip
