@José-Luis-Cánovas now that you mention it, directly connecting them via GPIO seems a little convoluted when you could just do what you suggested. I could make a server rack, getting ethernet cables isn't an issue, getting a switch and a load balancer system isn't an isse, it's now just a matter of saving up and getting 3-5 more omega 2's, AND ethernet expansions. It sounds like a super awesome project to do though.
@Chris-McCaslin Thanks, but I know about cross compilation on a Linux box - I do it all the time
My question related to performing compilation on the Omega itself, for which, as far as I can see, pretty well all the tools are available on the Omega with the glaring exception of make
The step you refer to in the tutorial you reference relates to using make menuconfig in an OpenWrt cross compilation environment. I have tried using that and nowhere within the menus do I find any reference to any package containing the make program.
Under make menuconfig I usually use the / command to search for program etc - doing so for make finds nothinpertaining to the make program itself.
