sudo apt-get install gnustep gnustep-devel gobjc
2. 示例代碼
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[])
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog (@"hello world");
[pool drain];
return 0;
}
3. 編譯
gcc `gnustep-config --objc-flags` hello.m -o hello -lgnustep-base
4. 運行
./hello
運行結果如下:
2016-01-04 14:16:03.705 hello[2405] hello world
