Hi
thanks a lot for your reply.
I'm not sure if you understood what I meant...
I'm a student of the Faculty of Mathematics & Computer Science at the
Warsaw University of Technology. I'm in my final year of my studies
(MSc) and I'm working on my final project.
The the subject of my project is: "Enhancing associative containers
(map, multimap, set and multiset) in STL with the possibility of
choosing the way of their implmentation".
So I'm going to develop libstdc++.
Now associative containers in STL are implemented by use of red-black
trees. What I want to do, is to enable the choice of implementation of
these containers by adding one parameter to the templates, so that the
containers could by be built by use of b-trees, just vectors or others
structures.
So my question is:
How to make changes in libstdc++ and how to test these changes in the
easiest way?
Thank you very much for your help.
My personal advice for doing this would be as follows.
1) Learn how to download, compile and install into a custom directory
all of gcc. You probably want to look at the options to only compile
certain languages (you only want C and C++)
2) Look in the libstdc++-v3 directory. I think everything you want
will be in the include directory. The actual headers you include
(<vector>, <list>, etc.) are in the std directory, for example vector
is called std_vector.h.
3) The actual implementations of the algorithms are in bits/. Explore
around in here to find the implementations.
When you have changed some, recompile by going into the libstdc++-v3 directory.
