I need to update the net package so that I can pass setSocketOption IP_TTL. This is a one line change. I'm using 5.02.2. There weren't any versions of Socket.hsc tagged as 5.02.2 in the CVS repository but there was one tagged Revision 1.2 / (download) - annotate - [select for diffs] , Fri Aug 17 12:51:08 2001 UTC (9 months, 3 weeks ago) by simonmar Branch: MAIN CVS Tags: ghc-5-02-branch, ghc-5-02-3, ghc-5-02-1, ghc-5-02 Changes since 1.1: +18 -12 lines Diff to previous 1.1 Track updates to hslibs/net I downloaded this and tried to compile but it has the following in it: instance Show Socket where ... and quite rightly the compiler complains. I'm going to take the latest version (although it would be nice to know which one was included in 5.02.2). 1.

Is my naive approach of just recompiling the relevant module going to work? I'd rather avoid having to build the whole of ghc if I can. Many thanks, Dominic Steinitz
