wpa_gui compilation

[João Mamede]

guys I'm trying to compile wpa_gui in my desktop everything compiles 
fine glibc version:2.3.6 gcc/g++ 4.0.3  qt 3.3.5
in my laptop I have glibc 2.3.6 gcc/g++ 4.0.3 qt(tried 3.3.5 and 3.3.6)
and I have this compilation error:
I've tried with make wpa_gui too in wpa_supplicant-0.4.7(tried 0.5.2 and 
0.5.1 versions too :( nothing)
