 Following your suggestion I am annexing the working and not working examples.
 The not working example compiles with g++ version 2.96, while version 3.0 gives
 
 $/usr/LOCAL/bin/g++ notworking.cc
 /tmp/ccHhDZuS.o: In function `main':
 /tmp/ccHhDZuS.o(.text+0x33): undefined reference to `A::a1'
 collect2: ld returned 1 exit status
 
 
 ========== notworking.cc
 
 #include<vector>
 #include<iostream>
 using namespace std;
 
 class A
 {
 public:
   static const int a1=10;
 };
 
 
 int main()
 {
   vector<A> v1(10);
   cout<< v1[1].a1<<endl;
 }
 
 
 ========working.cc
 
 #include<vector>
 #include<iostream>
 using namespace std;
 
 class A
 {
 public:
   static const int a1=10;
 };
 
 
 
 int main()
 {
   vector<A> v1(10);
   A p1(v1[1]);
   cout<< p1.a1<<endl;
 }
