Hi all, I'm still trying to get a Windows build (Win 7, tried both 32-bit and 64-bit, same result) -- using THREADS=1. When running 'sh validate', compilation eventually stops with "inplace/bin/ghc-stage1.exe" -hisuf hi -osuf o -hcsuf hc -static -H32m -O -Werror -Wall -H64m -O0 -package-name base-4.7.0.0 -hide-all-packages -i -ilibraries/base/. -ilibraries/base/dist-install/build -ilibraries/base/dist-install/build/autogen -Ilibraries/base/dist-install/build -Ilibraries/base/dist-install/build/autogen -Ilibraries/base/include -optP-DOPTIMISE_INTEGER_GCD_LCM -optP-include -optPlibraries/base/dist-install/build/autogen/cabal_macros.h -package ghc-prim-0.3.1.0 -package integer-gmp-0.5.1.0 -package rts-1.0 -package-name base -XHaskell2010 -O2 -O -dcore-lint -fno-warn-amp -fno-warn-deprecated-flags -no-user-package-db -rtsopts -odir libraries/base/dist-install/build -hidir libraries/base/dist-install/build -stubdir libraries/base/dist-install/build -dynamic-too -c libraries/base/./GHC/IO/FD.hs -o libraries/base/dist-install/build/GHC/IO/FD.o -dyno libraries/base/dist-install/build/GHC/IO/FD.dyn_o libraries\base\GHC\IO\FD.hs:281:23: Empty 'do' block libraries\base\GHC\IO\FD.hs:282:23: Empty 'do' block libraries\base\GHC\IO\FD.hs:283:26: Not in scope: `devptr' libraries\base\GHC\IO\FD.hs:283:33: Not in scope: `inoptr' libraries\base\GHC\IO\FD.hs:284:20: Not in scope: `devptr' libraries\base\GHC\IO\FD.hs:284:34: Not in scope: `inoptr' make[1]: *** [libraries/base/dist-install/build/GHC/IO/FD.o] Error 1 make: *** [all] Error 2 Since nobody else seems to be experiencing this, there must be something wrong with my setup? I've tried to follow http://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows best I could, but I'm not a Windows user so I might have got something wrong. Any suggestions welcome! Edsko
