Subject [jira] [Commented] (STDCXX-1067) Mac OS X port
Date Sun, 09 Sep 2012 00:15:07 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-1067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13451444#comment-13451444

Liviu Nicoara commented on STDCXX-1067:
---------------------------------------

The default, LLVM-based, C++ compiler shipped by Apple does not come with a C++ support library.
Instead, Apple  folds (almost) all C++ support in libc++, an implementation of the C++ Standard
library, leaving only a small layer outside, in the form of libc++abi, in order to facilitate
the portability of the C++ Standard Library.

Pathscale produces and released libcxxrt, based on libc++abi, which adds the missing C++ support
to libc++abi, effectively replacing gcc's libsupc++.

> The library does not configure properly and build on Mac OS X 10.7.x (Lion), with the
stock compiler (LLVM, using a gcc front-end). The main issue is the lack of a C++ support
library.
