Error when tried to build manually Hello Demo

[Le Bao TRUONG]

Hi all,

I would like build manually the 'Hello Tutorial' demo. But I have an
error to execute ./core.

I follow the tutorial :

1. Build the server side by make hello/server

2. Build the client side by

make drivers/timer
make hello/client

Then, the tutoriel told me to execute a binary ./core. But I couldn't
find core file in my bin/ directory so I build it by

make core hello/client

Then I execute ./core, my program is stopping at

int main(): --- create local services ---
int main(): --- start init ---
Could not open file "init"
ROM module "init" not present
int main(): transferred 79 MB to init

 
Would you like give me some advice ?

Thanks,

Le Bao
