Dieharder随机测试套件不编译

我试图使用dieharder来测试随机序列的质量。为了在Windows上编译它，我安装了msys和gsl开发。 GSL编译时没有任何问题。要编译Dieharder，我第一次运行./configure ，然后当我在MSYS进入make，它返回如下错误信息：Dieharder随机测试套件不编译

(cd libdieharder; \make) 
make[1]: Entering directory `/f/dieharder-3.31.1/libdieharder'

make[1]: Leaving directory `/f/dieharder-3.31.1/libdieharder'

错误消息是：

dab_dct.c: In function 'fDCT2': 
dab_dct.c:251:44: error: 'M_PI' undeclared (first use in this function) 
     output[i] += (double) input[j] * cos((M_PI/len) * (0.5 + j) * i);

我的问题是我是否应该申报文件开头的M_PI或我在安装过程中出错？

@KenWhite，对不起，你是对的。我已经添加了错误消息。 – David

常量在math.h中，您可以在其中找到M_PI。
