esignal and esig_asc error occured when installing HTK on WSL

Question

I'm installing HTK on the WSL on a windows machine. The .\configure run correctly but when i typed make all it can't work.

Here is the error code:

(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'

I edited the cofigure file to be -m64, this is while working on WSL in windows 10 machine.

I'm not sure where is this coming from, or maybe this is a compatibility issue with esignal. I can't solve it nor are there any similar questions on github or stack overflow. Please help.

I meet the same problem. After inserting a line #include<ctype.h> in the front of file HTKLib/esignal.h, the above errors are gone.

Apart form this error, I also need to delete some blank rows in some macro definitions where the compiler falied. It's worth to mention that command sed -i -e 's/\r$// file is used many times to remove the spurious CR characters of the configure file and all the generated makefiles, following this Ask Ubuntu question.
