Question

In my iOS project I need to use a C++ library consisting in some header (.h) files and a .a library file (I don’t have any actual source code).

In my Obj-c code I imported the .h header that I need, however Xcode doesn’t seem to understand it has to interpret the header as c++, in fact it returns an endless list of issues including “not found” errors on inclusions like theese:

#include <string>
#include <vector>

and other c++ language-specific syntax.
Unfortunately changing the .h extension to .hpp doesn’t solve the issue, and neither setting the file type to “C++ Header” in the Xcode file inspector does.

Any suggestion? Is there any flag I need to set somewhere to manually indicate to use g++ on the library files? Thanks.

You can import C++ headers only in Objective-C++ files, change your objc-file extension to .mm.
