Hello Martin, Here's just some minor additional context information... On 2015-01-01 at 19:01:53 +0100, Martin Foster wrote: [...]
- I note "./sync-all --help" says, under "Flags", that "--windows also clones the ghc-tarballs repository (enabled by default on Windows)", and I've confirmed that default behaviour experimentally - but https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources tells you to manually clone ghc-tarballs when on Windows. Is that line on the wiki obsolete, or am I overlooking something?
Somewhat related: when https://phabricator.haskell.org/D339 is landed, we can finally forget about having to clone that objectionable ghc-tarballs repo... [...]
I noticed that the cabal output made reference to "C:\Users\Martin\AppData\Roaming\cabal\", so tried moving that out of the way, but it only made the problem worse. I did figure it out eventually: in addition to that directory, "%APPDATA%\cabal", there were also files left over in "%APPDATA%\ghc". Once I removed that directory as well, things started working again - but it took me a lot of time & frustration to get there.
That's btw because Cabal/GHC uses `getAppUserDataDirectory "cabal"` and `getAppUserDataDirectory "ghc"` respectively... Cheers, hvr
