#686: cabal install - Codec.Compression.Zlib: incorrect header check ---------------------------------+------------------------------------------ Reporter: Monsikos | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.8.0.2 Severity: normal | Keywords: Zlib Difficulty: unknown | Ghcversion: 6.12.1 Platform: Windows | ---------------------------------+------------------------------------------ Comment(by Monsikos): After running "cabal --version" I confirm that I'm using the 0.8.2 version. I think it happens for all packages as every package I tried to install gave the same "incorrect header check" error. I unpacked the .tar.gz manually successfully and then installed the package manually with the "runghc Setup ..." commands. It works this way. {{{ Here is what I get when I run "cabal install binary-search -v" for example C:\Users\Paul>cabal install binary-search -v C:\Program Files\Haskell Platform\2010.1.0.0\bin\ghc.exe --numeric-version looking for package tool: ghc-pkg near compiler in C:\Program Files\Haskell Platform\2010.1.0.0\bin found package tool in C:\Program Files\Haskell Platform\2010.1.0.0\bin\ghc-pkg.exe C:\Program Files\Haskell Platform\2010.1.0.0\bin\ghc-pkg.exe --version C:\Program Files\Haskell Platform\2010.1.0.0\bin\ghc.exe --supported- languages Reading installed packages...
