error , Symbol 'vector' could not be resolved

Question

I am using eclipse in linux to develop a c++ application and I am getting this editor annotation error "Symbol 'vector' could not be resolved" from the following code lines

std::vector<unsigned char> buffer; 

I feel that some library is missing or the paths are not set. I explicitly downloaded STL but its of no use. Do I have to re install GCC on my linux ?

Answer 1

In Eclipse, right-click on the project name...Select Index...Rebuild.
