Hello all,
I have a little problem I haven't run into yet. I'm not sure if it's Reactive related, but that's what caused it for me, so I'm writing here. I managed to run Tetris.hs with reactive-0.10.3 and reactive- glut-0.1.4 with success (also observing the problems mentioned by Claus Reinke). Now I ran an update, and ghc -v says the following as expected:
hiding package reactive-0.10.3 to avoid conflict with later version reactive-0.10.5 hiding package reactive-glut-0.1.4 to avoid conflict with later version reactive-glut-0.1.6
However, when I try to compile Tetris or load it into ghci, it says that it can't match 'UI' (expected) with 'reactive-glut-0.1.4:FRP.Reactive.GLUT.UI.UI' (inferred) in dropPiece, and I've no idea where it is getting the latter from. There are no leftover .hi files or anything else in reach. Is reactive-fieldtrip a possible culprit?
That sounds like you've recompiled reactive-glut, but not reactive- fieldtrip afterwards (which depends on reactive glut). The result being that reactive-fieldtrip was type checked against an earlier version of reactive-glut than Tetris is being. Bob
