Hi folks,
I tried to build edison-1.2.0.1-sources with the command 'make system' but got:
*** Exception: Line 10: Unknown field 'hs-source-dirs'
I am using GHC 6.4.1. Any idea how to fix this?
You are probably using an older version of Cabal. You can either upgrade Cabal or, from the Edison README*: This version of edison builds correctly with Cabal version 1.1.4, which is shipped with GHC 6.4.2. To build on earlier versions, it should suffice to: s/UndecidableInstances/AllowUndecidableInstances/ s/Hs-Source-Dirs:/Hs-Source-Dir:/ in the .cabal files. The 'hs-source-dir' cabal directive was depreciated in 1.1.4, but perhaps I should have waited a bit longer to change it. OTOH, there isn't any good way to deal with the change in the undecidable instances flag, since it was outright changed. Grrrr..... *grumble* incompatible changes in minor releases *grumble*. (*) Further, grrrr... in the above, I've fixed several embarrasing typos in the text of the README.
Thanks, Lyle
