How to compile a C++0x code on Eclipse CDT on mac?

Question

有人可以指向标志和设置更改，以便在Mac上的Eclipse CDT上编译C ++ 0x代码吗？

Answer 1

To use C++0x in Eclipse CDT on OSX (in a managed make project):

• Open the project properties
• C/C++ Build
• Settings
• Change the "Command" field in "MacOS X C++ Linker" and in "GCC G++ Compiler" from g++ to c++ (before check that c++ is clang++ with "c++ --version" in a shell)
• Add "-std=c++0x -stdlib=libc++" in the "Miscellaneous" parameters of "GCC G++ Compiler"
• Add "-stdlib=libc++" in the MIscellaneous "Linker flags" parameters of "MacOS X C++ Linker"
• Open the "Discovery options", select the "GCC C++ compile" change g++ to c++ and add -std=c++0x to the "Compiler invocation arguments"
• Add "/usr/include/c++/v1" to the "includes" in "Paths and Symbols" in C/C++ General

The latest Apple gcc compiler is gcc 4.2 which does not support C+11 code. You need to install a gcc 4.6 - this can be done from source or there are some binaries at hpc this put the gcc in /usr/local/bin Then use that in the preferences fot the C++ compiler in eclipse.

Alternative for Lion and above Xcode 4.* includes clang the latest version of which doies much of C+11

If you want a later gcc macports (and fink and homebrew) have a later version as a port. As of July 2012 macports has 4.7.1 and a 4.8 beta. The package managers are often the easiest way to get complex compiled code onto your machine and they also have centrally compiled versions that will be downloaded by default.
