[OpenWrt-Users] packages vs executables files

[Daniel Baluta]

Hello ,

I have  installed openwrt ( kamikaze ) on a router and now i want to
make a simple hello world program.

AFAIK you cannot just simply gcc hello.c to get an executable file
because you dont have a gcc on openwrt.
I also  noticed that you can make packages outside and install into
router system.
My question : is there any other posibilty to run a program inside
openwrt without using package stuff? For example :
Create an executable using a cross-compiler outside , copy and run it
on openwrt.

thx.
