#8725: make DESTDIR=... install broken ----------------------------------------+---------------------------------- Reporter: nomeata | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Build System | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC failed | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ----------------------------------------+---------------------------------- Comment (by nomeata): After being told that others have not problem with `DESTDIR`, I narrowed it down a bit. I believe that `DESTDIR` can only work if `$ghclibexecdir` = `$ghclibdir`. Then, executing `$ghclibexecdir/bin/ghc` works because of the rpath of the binaries: {{{ 0x000000000000000f (RPATH) Library rpath: [$ORIGIN/../terminfo-0.4.0.0:$ORIGIN/../bin-package- db-0.0.0.0:$ORIGIN/../binary-0.7.1.0:$ORIGIN/../Cabal-1.18.1.3:$ORIGIN/../process-1.2.0.0:$ORIGIN/../pretty-1.1.1.1:$ORIGIN/../directory-1.2.0.2:$ORIGIN/../unix-2.7.0.0:$ORIGIN/../time-1.4.1:$ORIGIN /../old- locale-1.0.0.6:$ORIGIN/../filepath-1.3.0.2:$ORIGIN/../containers-0.5.4.0:$ORIGIN/../bytestring-0.10.4.0:$ORIGIN/../deepseq-1.3.0.2:$ORIGIN/../array-0.5.0.0:$ORIGIN/../base-4.7.0.0:$ORIGIN /../integer-gmp-0.5.1.0:$ORIGIN/../ghc-prim-0.3.1.0:$ORIGIN/../rts-1.0] }}} Debian has `$ghclibexecdir = $ghclibdir/lib`, so this breaks. The relative path here (`$ORIGIN/../$d`) is hard-coded in source:rules /build-package-way.mk and this issue was last addressed by [7dd7008f], in response to #3072. To fix this properly, instead of `..` one would have to calculate the relative path from `$ghclibexecdir/bin` to `$ghclibdir`. Or simply, and officially stop supporting such directory layouts. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8725#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
