#16259: Hadrian does not work with a cabal v2-installed "happy" -------------------------------------+------------------------------------- Reporter: RolandSenn | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.3 (Hadrian) | Keywords: | Operating System: Linux Architecture: | Type of failure: Building GHC Unknown/Multiple | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I installed happy with: {{{ cabal new-install --symlink-bindir=~/Software/ghc-8.6.3/bin happy }}} where `~/Software/ghc-8.6.3/bin` is in my PATH. When I run `hadrian/build.sh -c --flavour=devel2` I get the following error: {{{ happy: /home/roland/.cabal/share/x86_64-linux-ghc-8.6.3/happy-1.19.9 /HappyTemplate-arrays-coerce: openFile: does not exist (No such file or directory) }}} It's correct, I don't have a file `.cabal/share/x86_64-linux- ghc-8.6.3/happy-1.19.9/HappyTemplate-arrays-coerce`. However I have a file `.cabal/store/ghc-8.6.3/happy-1.19.9-84db80555b9a8f54be2ca475bccbc751401ffbff30194c8c26d08a002a665431/share /HappyTemplate-arrays-coerce`. If I do an old-fashioned `cabal v1-install happy`, it creates the missing file `.cabal/share/x86_64-linux-ghc-8.6.3/happy-1.19.9/HappyTemplate- arrays-coerce` and Hadrian is now able to build! Hadrian should not depend on old-style cabal installs!
