Question

I have a C++ class that compiles fine on linux with gcc and on widows in visual studio.

boid.h:

#ifndef BOID_CLASS_HEADER_DEFINES_H #define BOID_CLASS_HEADER_DEFINES_H #include 'defines.h'  class Boid {  public:      // Initialize the boid with random position, heading direction and color      Boid(float SceneRadius,float NormalVel);       ..... protected:      ... };  #endif 

and in boid.cpp:

#include 'Boid.h'  // Initialize the boid with random position, heading direction and color Boid::Boid(float SceneRadius,float NormalVel)  {     .... } 

However, I get the following error when I compile this code in Xcode:

Compiling Boid.h: 'error: vector: No such file or directory' 

Any ideas? I thought you could take C/C++ code and compile it in Xcode without issues?

Thanks

EDIT: Added defines.h (also added #endif to sample, but that was in the original code)

EDIT 2: I am getting a different error after a commenting out a couple of includes there were empty: the vector error above.

#ifndef BOID_NAV_DEFINES_H #define BOID_NAV_DEFINES_H #include <stdlib.h> #include <vector> #include 'Vector3d.h' #include 'Point3d.h' #include 'win_layer.h' #endif 

Answer 1

Are you including the C++ header in a .m file?

.m files are treated as .c files with Objective-C extensions.

.mm files are treated as .cpp files with Objective-C extensions, then it’s called Objective-C++

Just rename any .m file to .mm, right-click or ctrl-click and select rename on the file in Xcode.
