make文件这么写对么？为什么出错

[yangbc]

makefile:
就一个test.c文件，一个头文件a.h

test:test.o
gcc -o test test.o
test.o:test.c a.h
gcc -c test.c


可是make后，出现下面问题，各位高手指点一下
tbcs1:p6906:/bosshome/tbcs1/yangbc> make
"makefile", line 11: make: 1254-055 Dependency line needs colon or double colon operator.
"makefile", line 13: make: 1254-055 Dependency line needs colon or double colon operator.
make: 1254-058 Fatal errors encountered -- cannot continue.

[yangbc]

现在成了这个错误了
tbcs1:p6906:/bosshome/tbcs1/yangbc> make
"makefile", line 12: make: 1254-057 Shell command needs a leading tab.
"makefile", line 14: make: 1254-057 Shell command needs a leading tab.
make: 1254-058 Fatal errors encountered -- cannot continue.

test:test.o
gcc -o test test.o

test.o:test.c a.h
gcc -c test.c

Makefile中的动作，必须以TAB键开始。
建议看一下"跟我一起写 Makefile" (http://blog.csdn.net/haoel/category/9198.aspx)

Makefile中的动作，必须以TAB键开始

看看她报的错：“Shell command needs a leading tab“

[berniechen0123]

test:test.o
gcc -o test test.o

这样就ok了

[darkstar21cn]

berniechen0123() 正解
命令前面要加tab键

[zidane_yubo]

来晚了
test:test.o
gcc -o test test.o

test.o:test.c a.h
gcc -c test.c

gcc前tab键
