[Haskell-cafe] cabal install of HDBC-odbc fails on ghc 6.7, -I flag causes problems

[Thomas Hartman]

problemw with the -I flag to ghc are causing cabal install to fail for 
hdbc-odbc (darcs head).

man ghc still reports that -I is a valid flag after installing ghc 6.7 
from darcs head a couple days ago.

I think the problem might be the space after the -I flag (which is bad for 
both 6.6.1 and 6.7)

  -I / -e '' Setup.hs
ghc-6.7.20070816: unrecognised flags: -I

just a guess... 

anothing thing is it seems like there's a new INCLUDE pragma in 6.7. 
perhaps this should be used in one of the source files to get it to 
compile. but which one? I couldn't figure out what was causing 

  ghc -c -I dist/build/Database/HDBC/ODBC/Connection_hsc_make.c -o 
dist/build/Database/HDBC/ODBC/Connection_hsc_make.o

to be run. (I did try grepping on ghc but no luck, below.)

Any tips on debugging this cabal install would be appreciated.

thanks,

thomas
