整洁的C&x2B+；编译器错误Microsoft Visual Studio 2012 < P> >我想在微软Visual Studio 2012下运行以下C++库（2010）：

我已经修复了很多编译器错误，但是对于一些问题我没有找到解决方案。 编译器错误包括：

第一个错误发生在：

%experiments.cpp
 int evals[NEAT::num_runs];  //Hold records for each run 

所以这个值不是常数。如果我使用const int NEAT:：num_runs=1，我什么也不会改变

是否有人已经使用了此库，并且能够在visual studio下运行此库

致意

基本错误

error C4703: potentially uninitialized local pointer variable

只需使用NULL初始化变量，即可解决此错误。但实际上这并不是一个错误，而是一个警告，可能在项目设置中被关闭

在

genome.cpp、population.cpp、species.cpp中发生错误

所以C4703是唯一的错误
整洁实现的重要部分，这意味着它可以很容易地用Visual C++编写。
使用NEAT解决极点平衡任务时会出现其他错误。它们可能被当作用法的例子

是否有人已经使用了此库，并且能够在visual studio下运行此库

我已经提取了可以在其他VisualStudio项目中使用的从整洁到静态的链接库。解决方案中还有第二个项目作为使用niat.lib的示例


非基本错误

error C3861: 'lrand48': identifier not found

只需在VisualC++中使用rand（）

error C2133: 'evals' : unknown size

int evals[niat:：num_runs] >仅在VisualC++中使用此代码：<代码>：：NUMYRUX < /COD> >代码> const 。编译器必须知道
num\u runs
的值

int*evalsPtr=newint[niat:：num_runs]代码依赖于非标准的GCC扩展，VLAS在标准C++中是不合法的。重写它是不实际的，必须使用GCC。好的，谢谢，我现在使用GCC编译器的代码块。其中有些POSIX函数在Windows下不可用。我在Windows上有什么替代strdup（）的方法？在Windows上，它看起来像是一个叫做_strdup（）的函数，但编译器仍然说：“_strdup（..）没有在这个范围内声明”
RAND\u MAX
对于VC来说相当小，所以用
RAND（）
代替
lrand48
可能不够。@Joey我同意你的看法。但在这个项目的范围内，
rand（）
就足够了。在Windows、VisualC++中，有没有更好的替代代码“代码> LRAND48 <代码>？如果下一个代码> RANDMAX 不是问题，那么它应该是好的，但是一旦你需要一个大于32767的数字，那么我就不太情愿简单地推荐<代码> RAND（）/<代码>作为替换。
