#15257: Broken symlinks in lndir build tree -------------------------------------+------------------------------------- Reporter: adamgundry | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Build System | Version: 8.5 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: -------------------------------------+------------------------------------- I routinely create separate build trees using lndir (per wiki:WorkingConventions/Git#Creatingabuildtreewithlndir). However it seems this is currently broken by the code to copy `fs.{c,h}` to various places in `./configure` (see Phab:D4416): {{{ $ mkdir ghc-validate $ cd ghc-validate $ lndir ../ghc $ ln -s ../ghc/.git $ ./boot [...] $ ./configure [...] $ find . -name "fs.*" | xargs file ./rts/fs.c: broken symbolic link to ../../../ghc/utils/fs/fs.c ./rts/fs.h: broken symbolic link to ../../../ghc/utils/fs/fs.h ./utils/fs/fs.c: symbolic link to ../../../ghc/utils/fs/fs.c ./utils/fs/fs.h: symbolic link to ../../../ghc/utils/fs/fs.h ./utils/unlit/fs.c: symbolic link to ../../../ghc/utils/fs/fs.c ./utils/unlit/fs.h: symbolic link to ../../../ghc/utils/fs/fs.h ./utils/lndir/fs.c: symbolic link to ../../../ghc/utils/fs/fs.c ./utils/lndir/fs.h: symbolic link to ../../../ghc/utils/fs/fs.h ./libraries/base/include/fs.h: broken symbolic link to ../../../ghc/utils/fs/fs.h ./libraries/base/cbits/fs.c: broken symbolic link to ../../../ghc/utils/fs/fs.c }}} This can be fixed by manually correcting the symlinks, but it is a bit of pain, especially for `./validate`. {{{ ln -fs ../../ghc/utils/fs/fs.c rts/fs.c ln -fs ../../ghc/utils/fs/fs.h rts/fs.h ln -fs ../../../../ghc/utils/fs/fs.c libraries/base/include/fs.c ln -fs ../../../../ghc/utils/fs/fs.h libraries/base/include/fs.h ln -fs ../../../../ghc/utils/fs/fs.c libraries/base/cbits/fs.c }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15257 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
