I am compiling my program on my Linux 7.2 with gcc 3.0.2 and I got the following error. I did not get this error with gcc 2.95.2 Anyone knows how I can solve this problem? Thanks Philip test.cpp: -------- #include <vector> vector<int> ww; main() { } Error: test.cpp:2: 'vector' is used as a type, but is not defined as a type.
