#10473: Haskell Platform generic linux installer creates incorrect symlinks for /usr/local/man/man1 (and probably /usr/local/share/doc) when directory does not already exist -------------------------------------+------------------------------------- Reporter: brson | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Keywords: | Operating System: Linux Architecture: | Type of failure: None/Unknown Unknown/Multiple | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Following instructions here https://www.haskell.org/platform/linux.html for 'generic linux binaries'. After running activate-hs my /usr/local/man/man1 was a symlink to ghc.1 when it should be a directory *containing* ghc.1. This happens when the directory /usr/local/man/man1 does not already exist. Running activate-hs with --verbose --dryrun shows why: ln -sf usr/local/haskell/ghc-7.8.3-x86_64/bin/HsColour usr/local/haskell/ghc-7.8.3-x86_64/bin/activate-hs usr/local/haskell/ghc-7.8.3-x86_64/bin/alex usr/local/haskell/ghc-7.8.3-x86_64/bin/cabal usr/local/hask ell/ghc-7.8.3-x86_64/bin/ghc usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-7.8.3 usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-pkg usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-pkg-7.8.3 usr/local/haskell/ghc-7.8.3-x86_64/ bin/ghci usr/local/haskell/ghc-7.8.3-x86_64/bin/ghci-7.8.3 usr/local/haskell/ghc-7.8.3-x86_64/bin/haddock usr/local/haskell/ghc-7.8.3-x86_64/bin/haddock-ghc-7.8.3 usr/local/haskell/ghc-7.8.3-x86_64/bin/happy usr/l ocal/haskell/ghc-7.8.3-x86_64/bin/hp2ps usr/local/haskell/ghc-7.8.3-x86_64/bin/hpc usr/local/haskell/ghc-7.8.3-x86_64/bin/hsc2hs usr/local/haskell/ghc-7.8.3-x86_64/bin/runghc usr/local/haskell/ghc-7.8.3-x86_64/bin /runghc-7.8.3 usr/local/haskell/ghc-7.8.3-x86_64/bin/runhaskell /usr/local/bin ln -sf usr/local/haskell/ghc-7.8.3-x86_64/share/man/man1/ghc.1 /usr/local/share/man/man1 ln -sf usr/local/haskell/ghc-7.8.3-x86_64/share/doc/ghc /usr/local/share/doc usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-pkg register --verbose=0 --force usr/local/haskell/ghc-7.8.3-x86_64/etc/registrations/GLURaw-1.4.0.1 usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-pkg register --verbose=0 --force usr/local/haskell/ghc-7.8.3-x86_64/etc/registrations/GLUT-2.5.1.1 The second and third ln commands are incorrect. When there are multiple sources it treats the dest as a directory, but in these two instances there are only a single source so ln just creates man1 as a symlink. FWIW when this happens a subsequent install of Rust fails: https://github.com/rust-lang/rust-installer/issues/36. Rust v.
