Also, when I bootstrap on amd64 and apply https://ghc.haskell.org/trac/ghc/attachment/ticket/15411/Disable-unboxed- arrays.patch, the following happens: {{{ "inplace/bin/ghc-stage1" -hisuf hi -osuf o -hcsuf hc -static -O0 -H64m -Wall -this-unit-id base-4.12.0.0 -hide-all-packages -i -ilibraries/base/. -ilibraries/base/dist-install/build -Ilibraries/base /dist-install/build -ilibraries/base/dist-install/build/./autogen -Ilibraries/base/dist-install/build/./autogen -Ilibraries/base/include -Ilibraries/base/dist-install/build/include -optP-include -optPlibraries/base/dist-install/build/./autogen/cabal_macros.h -package- id ghc-prim-0.5.3 -package-id integer-simple-0.1.1.1 -package-id rts -this-unit-id base -Wcompat -Wnoncanonical-monad-instances -XHaskell2010 -O0 -no-user-package-db -rtsopts -Wno-trustworthy-safe -Wno-deprecated- flags -Wnoncanonical-monad-instances -odir libraries/base/dist- install/build -hidir libraries/base/dist-install/build -stubdir
#15916: GHC doesn't build on powerpc64 architecture on systems other than GNU / Linux -------------------------------------+------------------------------------- Reporter: pkubaj | Owner: trommler Type: feature request | Status: patch Priority: normal | Milestone: 8.10.1 Component: Compiler | Version: 8.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: powerpc64 Type of failure: Building GHC | Test Case: failed | Blocked By: 15411 | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | https://gitlab.haskell.org/ghc/ghc/merge_requests/81 -------------------------------------+------------------------------------- Comment (by trommler): Replying to [comment:20 pkubaj]: libraries/base/dist-install/build -c libraries/base/./GHC/Num.hs -o
libraries/base/dist-install/build/GHC/Num.o ghc-stage1: panic! (the 'impossible' happened) (GHC version 8.6.3 for powerpc64-portbld-freebsd): Can't use Natural in base }}} The error message says `powerpc64-portbld-freebsd` and it could also be #15411.
On openSUSE I conditionally apply the patch (workaround) only on powerpc64, but just for fun I applied it on all platforms and build (in my home project) passes no problem.
Without this patch, it compiles fine on amd64, but then fails on
powerpc64. The latter is due to #15411. There is another patch that I apply to 8.6.3. That patch fixes an issue mentioned in my comments on #15399. You can find the patch in Phab:D5001. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15916#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
