ObjectiveC大杂烩

1. Install gnustep

以 ArchLinux 为例

sudo pacman -S gnustep-base gnustep-make

2. Edit hello.m

#import <Foundation/Foundation.h>

int main(int argc, const char *argv[]) {
    NSLog(@"Hello world");
    return 0;
}

3. Compile

gcc gnustep-config --objc-flags hello.m -lobjc -lgnustep-base

4. Run

./a.out
