我正在windows机器上的WSL上安装HTK。.configure运行正确，但当我输入make all时，它不能工作。
错误代码:
(cd HTKLib && make HTKLib.a)
|| case "" in *k*) fail=yes;; *) exit 1;; esac;
make[1]: Entering directory '/mnt/c/Users/ts4016/AppData/Local/HTK-3.4/htk/HTKLib'

我将cofigure文件编辑为-m64，这是在windows 10机器上使用WSL时。
我不确定这是从哪里来的，或者这可能是信号的兼容性问题。我无法解决它，也没有任何类似的问题在github或堆栈溢出。请帮助。
我也遇到过同样的问题。在HTKLib/esignal.h文件前面插入#include<ctype.h>行后，上述错误就消失了。
除了这个错误，我还需要在编译器失败的一些宏定义中删除一些空白行。值得一提的是，命令sed -i -e 's/r$// file被多次用于删除配置文件和所有生成的makefile的虚假CR字符，遵循这个问Ubuntu问题。
