Program Size: data=148.0 xdata=0 code=2172

编译没错 连接 就是这些错了 ，我用的c51.小弟是新手请各位帮帮忙。
我的keil3 是注册 过的 我用的是c51语言做的程序，编译通过剩下连接。就出现这么多问题了。
compiling daojishi.C...
daojishi.C - 0 Error(s), 0 Warning(s).
我用的是 51单片机 SST-SST89E554RC
我用的是片内的存储器，是不是不够用要扩展。使用片外的存储器啊？？？？？

如果需要扩展那怎么扩展啊？？？？？？？？

Answer 1

Program Size: data=148.0 xdata=0 code=2172
Target not created

注意这个，你用的什么单片机？？器件类型选的哪一款？
-------------------------------
你看看工程的MCU是不是选错了，KEIL说的是你MCU的内存不够用，是不是选了标准的51？
----------------------------------
不用扩展，你的MCU是够用的。可能是你选错了器件类型。编译器认为你的MCU没有那么大内存

Answer 2

code=2172

超过了 51 的EPROM

你可以选择用 C52 来 linking.

Answer 3

内存不够，解决方法1.扩展内存。2.换用其他内存大的cpu，也有可能像3楼说的那样使用了标准51。3.减少全局变量定义，把部分DATA段定义为IDATA，这样Keil会自动覆盖，节约内存。因为你超出的不多，应该可以优化掉。
扩展内存方法
目标定义中增加XDATA，编译模式选择large就可以了。

Answer 4

你没全部编译吧

Answer 5

这个简单，把程序里面的
uchar
指令变成
uchar
xdata
就可以了
