Compiler Cpp apvector (apmatrix) errors with C++ 2011 [message #1744264]

We used Metrowerks CodeWarrior for years in our HS Cpp class.
Transitioning to eclipse we've done the MinGW installs, used the right toolchains etc.. Hello World works OK as does OneDWalk project in the attached project folder.
When we added position.h, position.cpp, utils.h, utils.cpp, apstring.h, apstring.cpp we get errors about files not compiling, not found libraries, etc. When we add the files it's looking for , more errors of the same kind happen.
We really want eclipse to work so we can toggle from Cpp to java and back. Python is going to happen here this year, too. These projects should run right out of the box , as is, and they don't. We're using Neon, updated MinGW, Win 7.
All project files are attached as well as the library of files we'd like to use.
FirstCpp is an eclipse project copied right from the workspace that is giving me guff for the last week and a half.
If there's any Eclipse Cpp masters in Western NY, I can arrange a visit.
If there's any awesome HS appropriate Cpp projects , send me some links, please.
Thanks

The first thing you might want to do is fix the C++ problems then worry about Eclipse.

I downloaded firstCpp and imported it.
I'm using Linux but tried to compile it anyway (actually Eclipse tried).

utils.cpp had an error:
line 50: void Sort(apvector<Fish> & list, int numElts)

After searching for "apvector", I found a line where the include for it was commented out (utils.h line 19).
The header file apvector.h is not in the project.

I couldn't find any declaration for class Fish.
But there is a commented out include for fish.h in utils.h line 20
There is no file fish.h in the project.

The build log:

No wonder you had grief.
I didn't bother with the other projects.

Well, that's embarrassing... Shocked

I'll check my source files Monday AM and see how it goes. Someone must have horsed around with our source...I can teach and remind to Save AS... but they forget sometimes..

You seem reluctant to show exactly what is giving you problems.
Instead, you are uploading your project expecting others to download it and magically know what is wrong.
Then provide fixes.
This is not the place for free consulting.

With the firstCpp project, you demonstrated that you are inclined to blame your tools for your mistakes.
You teach? If you can't solve your own problems how are you going to deal with beginner ones?

If you have specific questions, please ask them.
Otherwise, it's likely best you go back to what you've found that works.

Final disposition and report for future searches by anyone else in this situation:
The problem is that apvector (and hence apmatrix) is no// longer supported by C++. (#error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=gnu++111 compiler options.)
The Metrowerks IDE is long gone before 2011, it has settings to run certain projects without explicit #include's for every single file.
Thanks for the efforts here.
