not working examples after cabal build #10

michal-cab · 2015-11-07T03:38:06Z

hello,
i would appreciate some help because now i cannot follow examples in game in haskell book. :-(
im @ ubuntu 14.04, ghc 7.10.2.20151102 (current stable release), cabal 1.22.4.0. i installed game-in-haskell in sandbox as it is described in README.md. even cabal build went (almost) ok - it just spilled a lot of warnings concerning GLFW and many others - see below. all examples were built and found in /dist/build but if i try to run e.g. shapes-demo or frp-demo or others where there should be a window created simply nothing is happening. there is no window created.

i searched through issues about g-i-h and found jmillikan's post. but it is not helpful for me and does not work (spills: (conflict: game-in-haskell-book =>base>=4.7 && <4.8))

i guess there is something wrong under hood in GLFW or GLOSS. please any help or suggestions will be very helpful. thnx.

cabal build output with warnings (sorry for length, wanted to attach a file, but there are no permission to this rep.)
