Install Node.js - No GCC version

Greetings to all,

I'm trying to install node.js on my RT-AC68U running on the Advanced-Tomato 2.5-124.
I installed OPTWARE successfully and finally installed some dependancies for the node.js.

Now I am trying to compile node on my router but it seems that optware does not give any GCC.

Could you confirm that ?
Is there a way to get GCC on my router ?
I tried to find in google without any success
Thank you for your help
