Hello, I am starting to get in the groove related to runhaskell -- config/builds on top of cygwin (I haven't had time to carve up hard drive and install Linux). In any case, I really want to get the Unix package to build on cgywin (as advertised at http://hackage.haskell.org/cgi-bin/hackage-scripts/package/unix-2.2.0.0). When i do "runhaskell Setup.lhs configure" things seem to go fine, .log fine is clean, and pertinent cygwin include files like times.h are found, but when i do a "runhaskell Setup.lhs build" then the include files that are allegedly found during the configure "probe" cannot be found. ???? 1) During the "runhaskell Setup.lhs build" step, what human readable file is used and contains paths to the cygwin Posix include file directories? 2) thatis foloowing is a better approach for me .. => 2) Somebody obviously put " (except under Cygwin)". Can you point at who made this claim and why? Kind regards, Vasya
