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
I hope this will help. After updating xCode to version 10, I have had issues including < map > and < vector > libraries. Found an easy solution by changing the C++ library type in the project's build settings (target's Build Settings):
C++ Standard Library: libc++ (LLVM C++ standard library with C++ 11 support)
Compiled without any problem.
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.
Without changing any .m to .mm or anything like that, if you click your project, click tagets->build settings go all the way down to "LLVM GCC 4.2 - Languages" (new xcode says "Apple LLVM compiler 4.2") you will see Compile Sources As change that value to Objective-C++;
