S4_IMAGE environment variable not set.

[Viji]

Hi,

 

I followed the steps in the s4 site and build s4 and set build/s4_image folder path to S4_IMAGE environment variable.

 

Then i checked out twittertopiccount example and tried to install it. I get the below error.

 

viji@viji-VirtualBox:/opt/s4/s4/example/twittertopiccount$ sudo ./gradlew install

Environment variable S4_IMAGE not set.
> Loadingviji@viji-VirtualBox:/opt/s4/s4/example/twittertopiccount$ echo $S4_IMAGE
/opt/s4/s4/build/s4-image
viji@viji-VirtualBox:/opt/s4/s4/example/twittertopiccount$

 

Though the env variable is set i still i get the error.

 

I am new to Linux as well as to S4. Please help me on this.

 

Regards

Viji
