keil过错ERROR L105: PUBLIC REFERS TO IGNORED SEGMENT

在使用Keil C51编程时，发现程序逻辑上没有过错，但在衔接时却呈现了过错，如下：

*** ERROR L107: ADDRESS SPACE OVERFLOW

呈现以上过错的原因主要是第一个原因，第一个原因导致了它下面一切过错，第一个原因是：

ERROR L107: ADDRESS SPACE OVERFLOW

SPACE: DATA

SEGMENT: ?DT?GMNS_3V4

LENGTH: 0014H

阐明data空间现已不够用，原因是你可能有许多函数，而函数内部的局部变量又没有界说其空间，这种状况下，体系会将变量分配到你在Otions for Target 对话框里的设置的空间。假如你在下图所示中的 Memory Model 里设置成 Small:variables in DATA,则DATA空间很快便用完，导致data空间不够用。处理的方法有两种，一是经过更改Memory Model设置，能够设置成pdata或xdata，以便有足够大的空间，但这又带来新的问题，程序运转速度减慢，并且code代码也会加大，由于假如一个局部变量被存放在了xdata空间，汇编语言拜访xdata空间的代码巨细要比拜访data空间的代码大，变量一旦许多，程序的代码也会逐步增大；二是依据自己的要求设置变量的空间。所以这涉及到代码优化的问题，遇到具体问题时，在运转速度和代码巨细之间获得合适自己的状况。
