I'm using:
- FreeRTOS v7.4.0
- NXP LPC2368 MCU
- Red Suite 4
- Demo files : ARM7_LPC2368_Eclipse

I failed to open and build the demo project directly so I built a new project and copy all the files needed. The project I created is able to run 3-4 tasks(LED blink & uart) and I'm trying to do uIP now. So I copy all the files needed according to the makefile in demo project. I'm able to build the project after copy all the needed file over.

Here is the problem. When I try to add a new task for uIP. It states show error:
"make: *** [] Error1"
From the console:

I know the error lie on uip_process(u8_t flag) because it is able to compile if I comment out the whole content in this function. But this function has around 1200 lines. I don't know how to verify what problem it is.
