[Hackage] #922: “lexical error (UTF-8 decoding error)” in WIndows 7
#922: “lexical error (UTF-8 decoding error)” in WIndows 7 ---------------------------------+------------------------------------------ Reporter: hamukazu | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: minor | Keywords: UTF-8 Difficulty: unknown | Ghcversion: Platform: Windows | ---------------------------------+------------------------------------------ ==== Symptom ==== When I type
cabal install cabal it fails with the following error: Distribution\Compat\Exception.hs:0:4: lexical error (UTF-8 decoding error)
==== Environment ==== It happens with 64 bit version of Windows 7. It came to occur after I failed to install HXT. (I am not sure it is related.) ==== Workaround ==== By setting
set LANG=C in command line, cabal comes to work.
I regard this is just a workaround and this issue should be reported as a bug. ==== Related links ==== http://stackoverflow.com/questions/9371438/cabal-install-complains-built- in04-lexical-error-utf-8-decoding-error/9533205#9533205 http://trac.haskell.org/network/ticket/43 -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/922 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

This then blows up because ghc expects .hs files to be UTF8. Cabal can perhaps work around this cpp quirk by calling ghc/cpp with LANG=C. The new program launching utils in Cabal should make it easier to set env vars like this. It'd be useful if someone could confirm this hypothesis. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/922#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
