Diehard随机测试套件无法编译

Dieharder random test suite does not compile

我正在尝试使用diehard来测试随机序列的质量。为了在Windows上编译它，我已经安装了msys和gsl开发。GSL编译没有任何问题。为了编译Dieharder，我首先运行./configure然后当我在 msys 中输入 make 时，它会返回以下错误消息：

(cd libdieharder; make)
make[1]: Entering directory `/f/dieharder-3.31.1/libdieharder'
/bin/sh ../libtool  --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..  -DVERSION=3.31.1 -DLITTLE_ENDIAN=1 -I ../include -I /usr/local/include  -std=c99 -Wall -pedantic -g -O2 -MT libdieharder_la-dab_dct.lo -MD -MP -MF .deps/libdieharder_la-dab_dct.Tpo -c -o libdieharder_la-dab_dct.lo `test -f 'dab_dct.c' || echo './'`dab_dct.c

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在文件开头声明M_PI，还是在安装过程中犯了错误？

常

量在math.h中，你可以在那里找到M_PI。
