在Simulink，Mac OSX 10.9 Mavericks，Xcode 5，MATLAB 2012b中编译嵌入式MATLAB函数

Question

在我更新到最新的OSX Mavericks之后，我在Simulink中编译简单的MATLAB功能块时遇到了一些问题，如图和下面附带的代码。

function y = fcn(t)
   %#codegen
   %Simple MATLAB .m function to be compiled with the diagram

y = sin(t)+cos(t);

我在OSX 10.8 Mountain Lion下遇到了同样的问题，但我能够通过下载Mathworks补丁并按照this site上的说明解决问题。

使用新操作系统并升级到Xcode 5后，我按照this post中的说明更改了我的mexopts.sh文件中的编译器和SDK信息

#PATCH: MacOSX10.8
        CC='llvm-gcc-4.2'
        CXX='llvm-g++-4.2'
        SDKROOT='/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/'

        MACOSX_DEPLOYMENT_TARGET='10.8'
        ARCHS='x86_64'

到

#PATCH: MacOSX10.9
        CC='llvm-gcc'
        CXX='llvm-g++'
        SDKROOT='/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/'

        MACOSX_DEPLOYMENT_TARGET='10.9'
        ARCHS='x86_64'

运行mex -setup并重新启动MATLAB后，在尝试运行带有功能块的Simulink模型时出现以下错误（对于具有这些块的所有模型，行为相同）：

我认为Undefined symbols for architecture x86_64这是关键信息，但我真的不知道。有没有人有同样的问题，或者有人有解决方案吗？任何帮助将非常感激。谢谢！

Answer 1

搜索互联网并在此论坛上等待答案后没有结果，我的问题的解决方案最终升级到MATLAB 2013a。

此外，还需要对mexopts.sh文件进行一些修改。只需将10.7的所有实例替换为10.8或10.9。这两个都适合我，但我最终用10.9替换它，因为我正在运行小牛队。

可以在this site找到“官方”解决方案。
