我知道以前有人问过这些问题,但一切都建议使用 GNUStep。有没有办法在没有 GNUStep 的情况下使用 Foundation?这对我来说也是一个学习问题(比如是否可以通过链接文件或其他东西来完成)
我安装了 Cygwin 和 gcc。我从 CocoaTron 获得了所有库,如下所示:http ://code.google.com/p/cocotron/source/browse/
我将库文件夹添加到 OBJC_INCLUDE_PATH 和 C_INCLUDE_PATH 中,它不再抱怨找不到 Foundation.h。
但我收到其他错误,例如:
$ gcc intro.m -o intro
In file included from /cocoa/CoreFoundation/CFBase.h:144,
from /cocoa/CoreFoundation/CFAttributedString.h:8,
from /cocoa/CoreFoundation/CoreFoundation.h:42,
from /cocoa/Foundation/Foundation.h:37,
from car.h:1,
from intro.m:2:
/cocoa/CoreFoundation/CFString.h:88: error: parse error before "va_list"
In file included from /cocoa/Foundation/NSAffineTransform.h:9,
from /cocoa/Foundation/Foundation.h:41,
from car.h:1,
from intro.m:2:
/cocoa/Foundation/NSGeometry.h:9:32: Foundation/NSObject.h: No such file or directory

from car.h:1,
from intro.m:2:
对于新手问题,我很抱歉,我只是对运行一些测试感兴趣并且不想安装 GNUStep。
我的意思是,一个非常简单的例子,比如:
//car.h
#import <Foundation/Foundation.h>
@interface Car : NSObject{
}
- (void)addGas;
@end
#include <stdio.h>
#import "car.h"
int main(int argc, const char * argv[]){
printf("Hello");
return 0;
}
是的,我知道这个例子不需要 objC ;) 我只是想跟着教程一起学习。
谢谢您的帮助!
