Linking to a .a c++ Library in an Objective-C Project

Question

I'm trying to add support for iZotope (audio effects) in an Objective-C application.

During integration, I've ran into a number of problems related to linking the iZotope C++ library into my Xcode project.

As of this point I haven't done nothing else than:

• Add the libraries (.a) in TARGETS > MyTargetName > Build Phases > Link Binaries with Libraries
• Add the header files of the library to PROJECT > MyProjectName > Build Settings > Search Paths > Header Search Paths

I haven't written any code, at all. My goal for now is to get my project to compile, as it was before adding the libraries.

Here is a link to the compiler output (https://gist.github.com/dornad/6310107). To me it seems that Xcode has no idea about the c++ std library, so it fails spectacularly.

Any ideas?

Standard C++ libraries can not be found. Probably, the extension of your project files is .m instead of .mm, which is necessary for c++ compilation.
