std::vector debug and release build using g++
c++, debugging, g++, stl
Solution
The flag you want is `-D_GLIBCXX_DEBUG`
More debug options for libstdc++ can be found at:

Problem
Possible Duplicate: GCC STL bound checking Is there something like a automatic debug version of the std:vector in the g++ STL and if not how could I achive one? What I want is to specify a debug parameter in my g++ call for example: ``` g++ -D DEBUG_ main.cpp ``` When this parameter is defined I want all my std::vectors to check their boundarys when accesing an element, the way when using vector::at(). When the parameter is omitted I want all vectors to behave as if the normal [] operator is used, meaning no performance is "wasted" for boundary checking. I heard that VC++ does something like this. So my question is how to to this using the g++?
