#14739: Cannot compile ghc 8.2.1 or 8.2.2 on armv7l architectures -------------------------------------+------------------------------------- Reporter: mitchty | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Building GHC Unknown/Multiple | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Noticed while trying to build ghc 8.2.1, and ghc 8.2.2 on alpine linux armhf as well as nixos. Opening this ticket as I previously thought this was just some quirk of the alpine linux port but managed to find out from dhess on irc that nixos hits the same issue for both as well on armv7l arches. What happens. 8.2.1 logs, 8.2.2 has similar or the same issues, I was just double checking that 8.2.1 has the same problems. {{{ "inplace/bin/ghc-stage2" -hisuf dyn_hi -osuf dyn_o -hcsuf dyn_hc -fPIC -dynamic -H32m -O -Wall -hide-all-packag es -i -iutils/haddock/driver -iutils/haddock/haddock-api/src -iutils/haddock/haddock-library/vendor/attoparsec-0.13.1. 0 -iutils/haddock/haddock-library/src -iutils/haddock/dist/build -Iutils/haddock/dist/build -iutils/haddock/dist/build /haddock/autogen -Iutils/haddock/dist/build/haddock/autogen -optP- DIN_GHC_TREE -optP-include -optPutils/haddock/dis t/build/haddock/autogen/cabal_macros.h -package-id base-4.10.0.0 -package- id filepath-1.4.1.2 -package-id directory-1. 3.0.2 -package-id containers-0.5.10.2 -package-id deepseq-1.4.3.0 -package-id array-0.5.2.0 -package-id xhtml-3000.2.2 -package-id Cabal-2.0.0.2 -package-id ghc-boot-8.2.1 -package-id ghc-8.2.1 -package-id bytestring-0.10.8.2 -package-i d transformers-0.5.2.0 -funbox-strict-fields -Wall -fwarn-tabs -O2 -threaded -XHaskell2010 -no-user-package-db -rtsop ts -Wno-unused-imports -Wno-deprecations -Wnoncanonical-monad- instances -odir utils/haddock/dist/build -hidir uti ls/haddock/dist/build -stubdir utils/haddock/dist/build -c utils/haddock/haddock-api/src/Haddock/Backends/Hyperlink er/Types.hs -o utils/haddock/dist/build/Haddock/Backends/Hyperlinker/Types.dyn_o "inplace/bin/ghc-stage2" -hisuf dyn_hi -osuf dyn_o -hcsuf dyn_hc -fPIC -dynamic -H32m -O -Wall -hide-all-packag es -i -iutils/haddock/driver -iutils/haddock/haddock-api/src -iutils/haddock/haddock-library/vendor/attoparsec-0.13.1. 0 -iutils/haddock/haddock-library/src -iutils/haddock/dist/build -Iutils/haddock/dist/build -iutils/haddock/dist/build /haddock/autogen -Iutils/haddock/dist/build/haddock/autogen -optP- DIN_GHC_TREE -optP-include -optPutils/haddock/dis t/build/haddock/autogen/cabal_macros.h -package-id base-4.10.0.0 -package- id filepath-1.4.1.2 -package-id directory-1. 3.0.2 -package-id containers-0.5.10.2 -package-id deepseq-1.4.3.0 -package-id array-0.5.2.0 -package-id xhtml-3000.2.2 -package-id Cabal-2.0.0.2 -package-id ghc-boot-8.2.1 -package-id ghc-8.2.1 -package-id bytestring-0.10.8.2 -package-i d transformers-0.5.2.0 -funbox-strict-fields -Wall -fwarn-tabs -O2 -threaded -XHaskell2010 -no-user-package-db -rtsop ts -Wno-unused-imports -Wno-deprecations -Wnoncanonical-monad- instances -odir utils/haddock/dist/build -hidir uti ls/haddock/dist/build -stubdir utils/haddock/dist/build -c utils/haddock/haddock-library/src/Documentation/Haddock/ Types.hs -o utils/haddock/dist/build/Documentation/Haddock/Types.dyn_o make[1]: *** [utils/haddock/ghc.mk:21: utils/haddock/dist/build/Documentation/Haddock/Types.dyn_o] Segmentation fault (core dumped) make[1]: *** Waiting for unfinished jobs.... make[1]: *** [utils/haddock/ghc.mk:21: utils/haddock/dist/build/ResponseFile.dyn_o] Segmentation fault (core dumped) make[1]: *** [utils/haddock/ghc.mk:21: utils/haddock/dist/build/Haddock/GhcUtils.dyn_o] Segmentation fault (core dumpe d) make[1]: *** [utils/haddock/ghc.mk:21: utils/haddock/dist/build/Haddock/Backends/Hyperlinker/Types.dyn_o] Segmentation fault (core dumped) $ gdb /home/build/aports/community/ghc/src/ghc-8.2.1/inplace/lib/bin/ghc- stage2 src/ghc-8.2.1/core GNU gdb (GDB) 7.12.1 Copyright (C) 2017 Free Software Foundation, Inc.

(gdb) }}} I've been poking around but i'm a bit out of my depth here in understanding the ghc rts here and debugging it as well. But its curious that only the stage2 compiler is having issues being built and not stage0 or stage1. If needed/desired I can provide access/login to this box for debugging but its sloooow, ~29 hours to do a build to this point. But I'm willing to help move things along, ghc on arm is one of the main reaons for the port to alpine linux and 8.0.2 works fine. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14739 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
