opengl - How to get gloss to not close ghci?

Question

gloss is a nice library for graphics. The problem, is, when I run it in ghci, it closes ghci as soon as I exit. I tried using forkIO, but it still closes ghci after closing the window. How do I get gloss to not close ghci (or at least keep the history) or is it better to just use a file?

Answer 1

正如网站所建议的那样（http://gloss.ouroborus.net/）

A2: Try installing gloss to use the GLFW window manager 
interface instead of GLUT: cabal install gloss --flags="GLFW -GLUT"

我可以让它与 ghc-7.6.3 一起工作（在窗口中按 ESC 后，我回到 ghci）

但我无法为 ghc-7.8.4 编译它（因为 cabal 抱怨）

next goal: GLFW-b (dependency of gloss-1.9.2.1:+glfw)
