gsoap_gmtserver.cpp

Notes:

• there are three files in here
• aaa_currenttime.txt which contains the instructions (a Makefile is coming soon)
• gmtclient.cpp
• gmtserver.cpp

title   : aaa_currenttime.txt (gsoap currenttime demos)
edit    : 2021-12-14
author  : Neil Rieck
platform: Linux (CentOS-7.7) with gcc
purpose : steps to create currenttime gsoap server demo
ref1    : gsoapdoc283.pdf
ref2    : https://www.genivia.com/examples/time/index.html
legend  : ur (user response) is what you type
        : sr (system response) is what was displayed
notes   :
1) installed gsoap-2.8.16 via yum like so:
   yum install gsoap
2) gmtserver is run from Apache /cgi-bin (no plugin required)
3) gmtclient is only used to test gmtserver

command-1
=========
#soapcpp2 -c -C    currentTime.h	# c-only, client-side only
soapcpp2     -C    currentTime.h	# both  , client-side only

command-2
=========
g++ -o gmtclient gmtclient.cpp soapC.cpp soapClient.cpp	\
		-I/usr/include/ -lgsoap++

command-3
=========
soapcpp2     -S    currentTime.h        # both  , server-side only

command-4
=========
c++ -o gmtserver gmtserver.cpp soapC.cpp soapServer.cpp	\
		-I/usr/include/ -lgsoap++

command-5
=========
cp -p gmtserver /var/www/cgi-bin/

command-6
=========
./gmtclient	# test the client-side code
