[ECOS] function not found in extras.o

["kross at elands dot co dot nz" <kross at elands dot co dot nz>]

Hi,

We have created a library and built it using ecos-config. 
I get the error below to a simplified main.c

As you can see extras.o contians the wanted function. 

How do I get my app to talk to my driver?

any ideas to try.
