Cross compiling libjson-c : Make unsuccessful in libjson-c, Linkhash.c warning

Question

Should I add any flags to avoid this?

make  all-recursive
make[1]: Entering directory '/home/local/ZOHOCORP/vignesh-4691/Downloads/json-c-master'
Making all in .
make[2]: Entering directory '/home/local/ZOHOCORP/vignesh-4691/Downloads/json-c-master'

cc1: all warnings being treated as errors

Sure, find where -Werror is set and remove that flag. Then warnings will be only warnings.
