Thanx neil and Yuca for all your support.
This time I have Uninstalled the previous perl installed.
And Unintslaled the symbian^3 SDK also.
Started new Symbian^3 SDK installation and it has triggered active perl installation then I installed in C:\Perl\.
I checked in the Path of environment variable also it was showing "C:\Perl\" only
But still the error during the build or running of my App
perl eror2.jpg i.e Installation file Does not exist what it means ?
Failed to connect to USB:9. Be sure the Debug (CODA) service is available.
The communication port could not be opened. Either it is in use by another application or it does not exist on the system. OSError:
