[GHC] #7834: dyn way and INTEGER_LIBRARY=integer-simple
#7834: dyn way and INTEGER_LIBRARY=integer-simple -----------------------------+---------------------------------------------- Reporter: heisenbug | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- a standard bootstrap with {{{ perl boot ./configure make INTEGER_LIBRARY=integer-simple }}} causes some problems: 1. there is a panic (at least when `-j4`) "fromJust..." (which strangely disappears on the second attempt) 2. `__word_encode{Float|Double}` is not found by the linker. There are `__int_encode{Float|Double}` symbols available, though, and changing the source helps for linking, but not for correctness, obviously. I'll add specific details (if not trivially reproducible) as soon as I am back at my dev machine. The bottom line is that since GHC HEAD now builds the 'dyn' way by default, this kind of bootstrap always fails. Normally not a problem on desktop linux, but in combination with a gmp-less embedded linux and cross-compiling it becomes annoying. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7834 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
