Hello I am trying to port GHC to QNX machines. I followed the instructions in the document of porting GHC strictly. Everything went well until I came to the step $cd H/ghc/lib $make -k UseStage1=YES EXTRA_HC_OPTS='-O -fvia-C -keep-hc-files' I was given following error messages ------------------------------------- System/Directory/Internals.hs:1:0: Module `System.Directory.Internals' is a member of package base-1.0. To compile this module, please use -ignore-package base-1.0. ------------------------------------- I have tried to add the option, but then the compiler can not find Prelude. My host machine is running redhat9.0. It also has ghc-6.4 installed. Will that be the reason why I got this problem when creating a unregisterised GHC. Thanks, Liwen
