Linux-makefile执行出错的问题

Question

我在AIX下测试make编译一个小程序：
makefile文件：
edit: main.o 
cc -o main.o
main.o: main.c 
cc -c main.c
clean: 
rm edit main.o
程序cc编译通过，但是在make编译下显示出错，如下：
personal>make
"makefile", line 2: make: 1254-056 Shell command not associated with a dependency: edit: main.o cc -o .
"makefile", line 4: make: 1254-056 Shell command not associated with a dependency: main.o: main.c cc -.
"makefile", line 6: make: 1254-056 Shell command not associated with a dependency: clean: rm edit main.
make: 1254-058 Fatal errors encountered -- cannot continue.
求教大神解决下，谢谢

Answer 1

我用的是Linux，GNU make，下面OK：

edit: main.o
cc main.c -o edit

main.o: main.c
cc -c main.c

clean:
rm edit main.o

你写的实际等价于

 edit: main.o cc main.c -o edit

main.o: main.c cc -c main.c

clean: rm edit main.o
