我正与Borland Turbo C++编辑公司合作,使用WINDOWS机器,并在C撰写一部法典。
我想在我的计算中利用互补的错误功能。
However, when I run the code, the error is "Linker error: Undefined symbol _erfc in in module filename.c "
The problem here is erfc() and erf() are supposed to be included in the math.h library. However, these aren t available in mine.
请允许我告诉我,我如何能够将这些职能纳入我的方案?
谢谢。
很可能需要通过某种特殊选择,与数学图书馆连接。
Borland Turbo C++还可能支持erfc(功能。
在C,1990年ISO C标准t包括erfc(功能。 根据1999年的标准,在语言中添加了该词。 (不确定C++。) 我认为Borland Turbo++相当老。
起草一个称为<代码>sqrt(<>>/code>的小型方案。 如果你能够工作,<代码>erfc(>>仍然得不到承认,那么Borland不支持。
In the latter case, either get a newer compiler (there are a number of free ones, and that s probably a good idea in any case), or find an open source implementation of erfc().
你需要与数学图书馆联系。 在特殊机器上,通过<代码>-lm向联系人悬挂国旗,这意味着与一个名为校准的图书馆连接。 对博兰来说,或许需要做一些类似的事,但我不相信细节。 希望这将使你走到正确的方向。
