>> Per your previous threads, I recall you switched your MacPorts installation from libstdc++ to libc++. You've now discovered that the ivy-c port doesn't obey this setting (and also isn't using the right compiler or -arch flags). These are bugs in the ivy-c port that need to be fixed.

>     Thank you for your help again.I have installed Xcode(5.1.1),which should contains the libc++ with its command line.And I have cleaned everything in macport to reinstall it with the right compiler.But I don't know how to configure the compiler environment for it since I am not a professional developer of the osx,it's not easy for me.  : (

libc++ is part of OS X 10.8, not Xcode. But it is not the default C++ library on 10.8. If you still have the settings in your macports.conf that we talked about in the last thread about gringo, then you've configured MacPorts to use libc++. And hopefully you've uninstalled and rebuilt all ports that use C++.

But it is possible that some ports may not support this setting, and it looks like this ivy-c port you want to use is one of them. You need to report that bug to whoever provided that ivy-c port to you. It looks like you can contact them here:

If they don't understand what they need to do to fix the problem, they're welcome to write to the macports-dev mailing list and ask for help.
