Hi evreybody,

I’m trying to install legato on my linux ubuntu, and i’d like to test demo’s apps (HelloWorld) on localhost before usie target, but i don’t find commands to run it .  
i tried instapp myapp localhost, it doesn’t work. the same for startapp myapp localhost.  
i have tried to start legato on localhost with startlegato, but i don’t find the commande to run the app.

Would you please give me some suggestion to solve this problem?

Thank you.

Hi,

Here’s an example of how you can run the sample helloWorld app on localhost:

1. Build legato for localhost

2. Source legato environment

3. Run ‘startlegato’ script from bin directory.

4. Go to apps/sample/helloWorld and build helloWorld for localhost

5. When app is successfully built, go to \_build\_helloWorld/localhost/staging/bin and run binary.

Also you can stop the localhost version of legato by running ‘bin/stoplegato’.

I was looking for a solution to that too and I’m glad I found this topic. It worked for me in case of ‘hello world’.  
However when I define timer inside it does not work.  
I can compile HelloIpc - but it does not work too.

Do you have any suggestions to solve that?

Thanks for sharing @esun. Do you folks generally use this for unit testing?
