[zeromq-dev] ERROR WHEN I RUN THE EXAMPLES IN C

[Mellitus Ezeme]

Hi,


I recently started learning ZEROMQ and I am stuck somewhere. I tried to run the weather update examples(wuclient.c and wuserver.c) and I get the error below.


In file included from wuclient.c:5:0:
zhelpers.h: In function 's_sleep':
zhelpers.h:133:5: warning: implicit declaration of function 'nanosleep' [-Wimplicit-function-declaration]
zhelpers.h: In function 's_console':
zhelpers.h:158:5: warning: implicit declaration of function 'time' [-Wimplicit-function-declaration]
zhelpers.h:159:12: warning: implicit declaration of function 'localtime' [-Wimplicit-function-declaration]
zhelpers.h:159:26: warning: initialization makes pointer from integer without a cast [enabled by default]
zhelpers.h:161:5: warning: implicit declaration of function 'strftime' [-Wimplicit-function-declaration]
zhelpers.h:161:5: warning: incompatible implicit declaration of built-in function 'strftime' [enabled by default]
wuclient.c: At top level:
zhelpers.h:60:1: warning: 's_send' defined but not used [-Wunused-function]
zhelpers.h:67:1: warning: 's_sendmore' defined but not used [-Wunused-function]
zhelpers.h:75:1: warning: 's_dump' defined but not used [-Wunused-function]
zhelpers.h:115:1: warning: 's_set_id' defined but not used [-Wunused-function]
zhelpers.h:125:1: warning: 's_sleep' defined but not used [-Wunused-function]
zhelpers.h:139:1: warning: 's_clock' defined but not used [-Wunused-function]
zhelpers.h:156:1: warning: 's_console' defined but not used [-Wunused-function]


The command I used to compile it is: gcc -Wall wuclient.c -o wuclient -L/usr/local/lib -lzmq


I opened the "zhelpers.h" file and "time.h" was included. So I got confused on why this would happen. Am using Ubuntu 12.04 and please, I am neither an expert in C or ZEROMQ but this software looks like my realistic hope of scaling my thesis hurdle.

Thank you in anticipation of your help.
