I tested linux and found that it failed on a binary with no executable privileges. I didn't go to the extra effort of trying to make dependent .so's nonexecutable. But, I have confirmed that it is unaffected if a dependent .so is executable. So I can't claim that this is completely a linux compatibility feature. But, yes, you are correct that I don't think it's worthwhile to rewrite ldd to deal with this issue. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
