NEAT C++編譯器錯誤微軟的Visual Studio 2012

Question

我想微軟的Visual Studio 2012下運行下面的C++庫（2010年）：

http://nn.cs.utexas.edu/?neat-c

我已經固定了很多編譯器錯誤的，但對於有些問題我找不到解決辦法。 編譯器錯誤是：

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== 

在neat.cpp存在以下定義：

%neat.cpp 
... 
int NEAT::num_runs = 1; 
... 

在接着發生的第一錯誤：

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

所以不知何故該值不不變。如果我使用const int NEAT :: num_runs = 1，我什麼都不會改變;

有人已經使用這個庫，並能夠在Visual Studio下運行這個？

問候 塞比

Answer 1

基本錯誤

error C4703: potentially uninitialized local pointer variable 

只是用NULL草簽變量解決了這個錯誤。但實際上這不是一個錯誤，它是警告，它可能會在項目設置中關閉。發生

錯誤genome.cpp, population.cpp, species.cpp

所以C4703僅在NEAT實施 必不可少的一部分，這意味着它可能會用Visual C++輕易地編譯錯誤。

使用NEAT解決極點平衡任務時會發生其他錯誤。他們可能被視爲使用NEAT的例子。

有人已經使用這個庫，並能夠在Visual Studio下運行這個？

我已經提取NEAT靜態鏈接庫，可以在其他Visual Studio項目中使用。並且在解決方案爲例用法NEAT.lib

第二個項目

不是必需的錯誤

error C3861: 'lrand48': identifier not found 

就在VISUALC使用蘭特（）++。

error C2133: 'evals' : unknown size 

int evals[NEAT::num_runs]; - 你可以在Visual C使用此++只有NEAT::num_runs是const。編譯器必須知道num_runs的值。

int *evalsPtr = new int[NEAT::num_runs]; - 在其他情況下，使用本
