在GNUStep上编译和执行Objective-C

1. 以下是你的Objective-C源文件（hello.m） include $（GNUSTEP_MAKEFILES）/common.make

TOOL_NAME = hello
hello_OBJC_FILES = hello.m

include $（GNUSTEP_MAKEFILES）/tool.make 2. 准备如下makefile，并命名为GNUmakefile #import <Foundation/Foundation.h>

int main （int argc, const char * argv[]）
{
        NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

        NSLog （@"hello world"）;
        [pool drain];
        return 0;
} 3. 编译 $ make
This is gnustep-make 2.6.1. Type "make print-gnustep-make-help" for help.
Making all for tool hello...
Compiling file hello.m ...
Linking tool hello ... 4. 执行 $ ./first
