After installation of "MyCRM Connector Tool", followed the procedure described in manual.
The test machine shows successful result when configured Google calander under My Account.
But production CRM gives following error.
"Fatal error: Call to undefined function curl_init() in /home/path/googlecal/MyCurl.php on line 32"
The solution is install php5-curl libraries.
root@server:~# sudo apt-get install curl libcurl3
root@server:~# sudo apt-get install php5-curl
root@server:~# apt-get install php5
I also restarted the mysql server and apache2 just for precaution, not necessary.
Recheck settings after entering my Google email address it worked.
Got this message.
