Incomprehensible error messages
by David Fox 06 Jun '07

06 Jun '07

I created this file by simplifying an error I was getting from a program that uses the Javascript types. If you remove the type signatures for f1 and f2 it compiles, but how do I fix the error I get when I compile with the signatures? module Main where type CPS c a = (a -> c) -> c class CNode a data TNode = TNode instance CNode TNode m :: TNode -> TNode -> Bool m a b = f1 b a $ \_ -> True f1 :: (CNode a, CNode b) => a -> b -> CPS c a f1 a b f = f2 a b $ \_ -> f a f2 :: (CNode a, CNode b) => a -> b -> CPS c a f2 a b f = f1 a b $ \_ -> f a This gives these messages: yhc -linkcore Browser3.hs Compiling Main ( Browser3.hs ) -- during after type inference/checking Error: No default for Main.CNode at 16:1-16:29.(Id 215,[(Id 200,Id 250)]) Error: No default for Main.CNode at 16:1-16:29.(Id 214,[(Id 200,Id 251)]) Error: No default for Main.CNode at 13:1-13:29.(Id 220,[(Id 200,Id 248)]) Error: No default for Main.CNode at 13:1-13:29.(Id 219,[(Id 200,Id 249)]) You can replace the CNode/TNode and CPS declarations with this: import DOM.Level1.Html import DOM.Level1.Dom import CPS same result.

Building Yhi on Windows
by Neil Mitchell 04 Jun '07

04 Jun '07

Hi, We haven't had buildbot going through with Yhi on Windows for quite a while, because I upgraded to Visual Studio 2005, and the .obj files started going all wrong. I've now managed to get a VS 2005 project file which builds Yhi on my computer, so the knowledge on how to compile Yhi on my machine is in that project file - we need to figure out the difference and put it back into the scons scripts. I suspect I'll need Andrews help for that. I've also got some warnings, I've fixed a few but there are some left: 1>d:\sources\yhc\current\src\runtime\bckernel\hashtable.c(20) : warning C4018: '>=' : signed/unsigned mismatch 1>d:\sources\yhc\current\src\runtime\bckernel\info.c(64) : warning C4244: '=' : conversion from 'Int' to 'HUInt', possible loss of data 1>d:\sources\yhc\current\src\runtime\bckernel\primitive.c(143) : warning C4244: '=' : conversion from 'unsigned long' to 'HUInt', possible loss of data 1>d:\sources\yhc\current\src\runtime\bckernel\primitive.c(146) : warning C4244: '=' : conversion from 'Word' to 'HUInt', possible loss of data 1>d:\sources\yhc\current\src\runtime\bckernel\builtin\system.c(30) : warning C4013: 'mkdir' undefined; assuming extern returning int 1>d:\sources\yhc\current\src\runtime\bckernel\builtin\system.c(34) : warning C4013: 'rmdir' undefined; assuming extern returning int 1>d:\sources\yhc\current\src\runtime\bckernel\builtin\system.c(53) : warning C4013: '_getcwd' undefined; assuming extern returning int 1>d:\sources\yhc\current\src\runtime\bckernel\builtin\system.c(53) : warning C4047: 'initializing' : 'Char *' differs in levels of indirection from 'int' 1>d:\sources\yhc\current\src\runtime\bckernel\builtin\system.c(64) : warning C4013: 'chdir' undefined; assuming extern returning int 1>d:\sources\yhc\current\src\runtime\bckernel\hsffi.c(343) : warning C4715: 'hsffi_ffiArgType' : not all control paths return a value 1>d:\sources\yhc\current\depends\ctypes\libffi_msvc\ffi.c(113) : warning C4018: '>' : signed/unsigned mismatch Hopefully we'll have an alive Windows buildbot quite shortly, which is good because that Windows machine generates our binary snapshots and haddock documentation! Thanks Neil
