#10822: GHC inconsistently handles \\?\ for long paths on Windows ---------------------------------+---------------------------------------- Reporter: snoyberg | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Windows | Architecture: Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+---------------------------------------- Comment (by dobenour): CoreCLR ran into the same problem and fixed it by adding the {{{\\?\}}} prefix to any overlong path, after making the path absolute with the {{{GetFullPathNameW}}} function in the Windows API. For UNC paths (that begin with {{{\\}}} but not with {{{\\?\}}}), the solution is to replace {{{\\}}} with {{{\\?\UNC\}}}. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10822#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
