ok, the -s option lets you expand the list of file suffixes used, i.e., "-sghc" would take care of it your case. --sigbjorn ----- Original Message ----- From: "Hal Daume III" To: "Sigbjorn Finne" Cc: "GHC Users Mailing List" Sent: Wednesday, May 29, 2002 16:57 Subject: Re: specifying common 'dis's in greencard

Ah, my problem was that I was using the extension ".ghs" on my "Foo" file and it expected ".gc".

Thanks.

Something like:

foo$ cat Foo.gc module Foo where import StdDIS %dis foo x = char x

foo$ cat Bar.gc module Bar where import StdDIS import Foo %fun f :: Foo -> IO ()

foo$ green-card -i/path/to/green-card/lib/ghc -tffi Bar.gc foo$

Hi,

I have three modules which all use the same (or some of the same) %dis directives; I'd like to pull these out into their own file (a module called "MyDIS" or something), but I can't figure out how to get green-card to look at those definitions (I've `import`ed it in the modules that need it and put it's directory in the search path with -i). Unfortunately, even so it complains that it doesn't know how to marshall my datatypes.

Any suggestions?

- Hal
