Dear All, The next release of C2HS (version 0.26.1) will have some changes that could conceivably cause problems in some rare cases. To summarise: C2HS will now manage imports of Haskell library modules that it needs for marshalling functions itself, rather than relying on the user writing "import Foreign.C.Types" everywhere... You can read about the details of the changes and the potential problems here: https://github.com/haskell/c2hs/blob/master/import-handling.md I'm not going to release this to Hackage for a couple of weeks to allow people to try the new version in advance, in case there are problems. Let me know if you do find any problems so that I can fix them before releasing this. Cheers, Ian. -- Ian Ross Tel: +43(0)6804451378 ian@skybluetrades.net www.skybluetrades.net
