I'm trying to build lambdabot 4.0 with ghc-6.4.1 (gcc (GCC) 3.4.2 (mingw- special)) and Cabal-1.1.6.1 on WinXP SP2. I've got as far as Plugin.Pl.Transform.hs, and I get *** Mangler g:\ghc\ghc-6.4.1\perl g:\ghc\ghc-6.4.1\ghc-asm C:\DOCUME~1\IAINAL~1\LOCALS~1\Tem p\ghc2736.raw_s C:\DOCUME~1\IAINAL~1\LOCALS~1\Temp\ghc2736.s 4 Prologue junk?: _s7f7_ret: xorl %ecx, %ecx xorl %eax, %eax movl %ecx, 8(%esp) movl %eax, 12(%esp) /APP Transform.hs uses {-# OPTIONS -fvia-C -O2 -optc-O3 #-} I've tried and failed to make sense of why the mangler's failing. I don't know if this is a known problem with 6.4.1 on XP. I'm not sure what to try next. I could turn off the aggressive optimisation, but I don't know how much that would cost me. I've got 6.4.2 installed, so I could try that, although I'd need to rebuild all the prerequisites. Anything else? -- Iain Alexander ia@stryx.demon.co.uk
