From a clean build I'm getting this
ld: cannot find libraries/ghc-prim/dist-install/build/GHC/CString.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/Classes.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/Debug.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/IntWord64.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/Magic.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/PrimopWrappers.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/Tuple.o: No such file or directory ld: cannot find libraries/ghc-prim/dist-install/build/GHC/Types.o: No such file or directory And indeed those files don't exist. In earlier builds they were there. The command line for eg CString was "inplace/bin/ghc-stage1" -hisuf hi -osuf o -hcsuf hc -static -O0 -H64m -Wall -fllvm-fill-undef-with-garbage -Werror -this-unit-id ghc-prim-0.5.3 -hide-all-packages -i -ilibraries/ghc-prim/. -ilibraries/ghc-prim/dist-install/build -Ilibraries/ghc-prim/dist-install/build -ilibraries/ghc-prim/dist-install/build/./autogen -Ilibraries/ghc-prim/dist-install/build/./autogen -Ilibraries/ghc-prim/. -optP-include -optPlibraries/ghc-prim/dist-install/build/./autogen/cabal_macros.h -package-id rts -this-unit-id ghc-prim -XHaskell2010 -O -dcore-lint -dno-debug-output -ticky -no-user-package-db -rtsopts -Wno-trustworthy-safe -Wno-deprecated-flags -Wnoncanonical-monad-instances -odir libraries/ghc-prim/dist-install/build -hidir libraries/ghc-prim/dist-install/build -stubdir libraries/ghc-prim/dist-install/build -split-objs -dynamic-too -c libraries/ghc-prim/./GHC/CString.hs -o libraries/ghc-prim/dist-install/build/GHC/CString.o -dyno libraries/ghc-prim/dist-install/build/GHC/CString.dyn_o which looks right. What's going on? This has me totally stalled. Simonb
