Sure, the initial compilation will succeed, or at least it won't error out with a missing file, but since whatever library functions or OS features the header file describes don't actually exist on your system, it isn't going to help any: it'll probably all fall apart at the final link stage. BTW and FYI, here's the generic recipe for figuring out the answer to these sorts of question: stropts.h (a moment's googling shows me) is related to POSIX streams functionality. By searching for the keyword streams in the Posix spec at http://www.opengroup.org/onlinepubs/007904975/nframe.html I found a few of the functions involved were fattach, fdetach, putmsg, putpmsg. By searching in the cygwin api reference at http://cygwin.com/cygwin-api/cygwin-api.html I couldn't find any of those functions. So my deduction is that the POSIX streams functionality isn't implemented by cygwin and therefore it's no surprise the header isn't there. This also means that the program you are trying to compile depends on OS functionality that cygwin doesn't provide, and so porting it to cygwin will never be a simple configure'n'make. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
