I have an lhs file, 'starsystem.lhs' that is not compiling because of a parse error. Specifically: $ cabal build Preprocessing executables for starsystem-0.1... Building starsystem-0.1... [1 of 4] Compiling Render ( Render.lhs, dist/build/ starsystem/starsystem-tmp/Render.o ) [2 of 4] Compiling Passive ( Passive.lhs, dist/build/ starsystem/starsystem-tmp/Passive.o ) [3 of 4] Compiling Active ( Active.lhs, dist/build/ starsystem/starsystem-tmp/Active.o ) [4 of 4] Compiling Main ( starsystem.lhs, dist/build/ starsystem/starsystem-tmp/Main.o ) starsystem.lhs:29:0: parse error on input `main' The location is at the first instance of main:
data Action = Action (IO Action)
The main program is mostly book-keeping such as initializing OpenGL and GLFW, creating window, setting up viewport, etc. \begin{code} main :: IO () -- ** line 29 main = do c_unbundled GLFW.initialize -- open window I cannot figure out what the problem here is. I have tried it in a regular hs file and it works. I have posted full source here: http://hpaste.org/fastcgi/hpaste.fcgi/view?id=25352#a25352 Any thoughts would be welcome.
