#16187: Hadrian: Build fails when using absolute path for build root -------------------------------------+------------------------------------- Reporter: davide | Owner: sykloid Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.3 (Hadrian) | Keywords: hadrian build Resolution: | root relative absolute path Operating System: Linux | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Marge Bot ): In [changeset:"2ff77b9894eecf51fa619ed2266ca196e296cd1e/ghc" 2ff77b9/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="2ff77b9894eecf51fa619ed2266ca196e296cd1e" Handle absolute paths to build roots in Hadrian. Fixes #16187. This patch fixes various path concatenation issues to allow functioning builds with hadrian when the build root location is specified with an absolute path. Remarks: - The path concatenation operator (-/-) now handles absolute second operands appropriately. Its behavior should match that of POSIX () in this regard. - The `getDirectoryFiles*` family of functions only searches for matches under the directory tree rooted by its first argument; all of the results are also relative to this root. If the first argument is the empty string, the current working directory is used. This patch passes the appropriate directory (almost always either `top` or `root`), and subsequently attaches that directory prefix so that the paths refer to the appropriate files. - Windows `tar` does not like colons (':') in paths to archive files, it tries to resolve them as remote paths. The `--force-local` option remedies this, and is applied on windows builds. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16187#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
