Ubuntu 15.10 : undefined reference to poco [solved]

Well, I downloaded the stable branch on github and the compiling worked perfectly, still I couldn't get the master working. There is one error when compiling poco I didn't get with the stable version, about a

rm *d.a

which didn't exist.
Thanks a lot for your answers, if you still wish to solve this problem I can send you other compiling outputs.
