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

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
