You have to define the parameters (P, ...) as "global":

global P;
P = 3;
...

in the main program (or where they are initialized) and in the objective 
function as well. 

This the following works for me:
--
function y=func(x)
global P;

y = P - 2*x;

endfunction;


global P;

P = 8;
res = fsolve("func", 10)
