How much memory does GHC need to build on amd64 GNU/Linux? I'm trying to build from the darcs repository, and this command "inplace/bin/ghc-stage1" -H32m -O -package-name terminfo-0.3.1.1 -hide-all-packages -i ilibraries/terminfo/. --ilibraries/terminfo/dist-install/build -ilibraries/terminfo/dist-install/build/autogen -Ilibraries/terminfo/dist-install/build -Ilibraries/terminfo/dist-install/build/autogen --Ilibraries/terminfo/. optP-include -optPlibraries/terminfo/dist-install/build/autogen/cabal_macros.h -package base-4.2.0.0 -package extensible-exceptions-0.1.1.1 -split-objs -Wall -XForeignFunctionInterface -XDeriveDataTypeable -XEmptyDataDecls -XScopedTypeVariables -XFlexibleInstances -O2 -XGenerics -fno-warn-deprecated-flags -odir -libraries/terminfo/dist-install/build -hidir -libraries/terminfo/dist-install/build -stubdir -libraries/terminfo/dist-install/build -hisuf hi -osuf o -hcsuf hc --c libraries/terminfo/./System/Console/Terminfo/Effects.hs -o -libraries/terminfo/dist-install/build/System/Console/Terminfo/Effects.o needs more than 3.5 GB of RAM. Or is this some sort of miscompilation problem? (I'm trying to bootstrap with GHC 6.12.1, but saw this with GHC 6.8 as well.) The start of the context is this: [Remove an out-of-date comment Ian Lynagh **20100122130853] [fix build on Windows Simon Marlow **20100122121016 Ignore-this: cd690a8eff71ca4f87fe67a41a20f493 ] [fix warning on Windows Simon Marlow **20100122120328 Ignore-this: 507a91e356a667dcecf8bec621fd2b95 ]
