Virtual memory exhausted: Cannot allocate memory on Raspberry Pi with 16GB class10 SD memory card.

[Sasko Karakulev]

Dear Kaa's

I know that this is trivial question but I don't know how to free-up system resources on my current e. Actualy I'm not sure how much resources are needed in order to

./build.sh deploy notification_demo according  Kaa documentations.  Please let me know do I have enough resources to make notification_demo works?

As I said during ./build.sh deploy I get following printout

Please advice do I have enough resources or what I have to do to free-up? Should I extend 16GB SD card to 32GB?

help is highly appreciated.

Thanks in adavnce

And as usual I succeed to find solution after posting the questions... :-)

So the answer/solution  is described here  memory exhaust solution. Briefly we have to extend swap size from 100MB (raspberry default). I make it from 100MB to 1024MB for my C++ 4.8 compiler

Cheers
