Search your code for the missing symbols/functions (d2iz, dcmeq, etc.)
It look's like a missing (standard) library.

Hi Duke,

These symbols are not in my code. These are the result of the 
compilation, it seems that some operations are interpreted in asm as 
floating point operations. I think the problem is in the linking stage 
but I'm not able to figure it out.

found some code to fix it on the web.
