@konglinglong I cannot reproduce the problem, but it seems to happen in those lines:
https://github.com/zeromq/libzmq/blob/master/version.sh#L10-L16

Could you please execute each of these egrep commands on their own and report their output here?

egrep '^#define +ZMQ_VERSION_MAJOR +[0-9]+$' include/zmq.h
egrep '^#define +ZMQ_VERSION_MINOR +[0-9]+$' include/zmq.h
egrep '^#define +ZMQ_VERSION_PATCH +[0-9]+$' include/zmq.h

Also, information about your OS might be helpful.

I execute the egrep commands just you told me,there is nothing.
I delete the '+$' characters,and it is OK.
