I downloaded
https://github.com/maciej-izak/generics.collections
and put the "src" and "inc" directories in the project=>options=> other unit files
in the "uses" I added "Contnrs" and "Generics.Collections"
I get identifier not found while putting in the code
type
b=TQueue;
a= TDictionary;

Try this:
01. Start a new project
02. Lazarus main menu >
File
>
Open
03. Browse to the [location]
\src
04. Open the file named
generics.collections.pas
05. Lazarus main menu >
Project
>
Add Editor File to Project
06. Answer
Yes
(when asked Add to unit search path?)
07. Goto the tab
unit1
(your source code)
08. Type
Generics.Collections
in the uses clauses
09. It should work now

There is some progress. Type definitions are OK.
but I get the message
The GDB command:
"-environment-cd "C:/Users/mariu/AppData/Local/Temp/""
returned the error:
",msg="C:/Users/mariu/AppData/Local/Temp/: Permission denied.""
I do not know where to set this to a different directory

I use Linux but my guess is you had not save the project. Try to save the project first before running:
Lazarus main menu > File > Save All

I had to start a new project as there were some errors unsolvable. Repeated everything and get the same message "identifier not found" regarding Tqueue and Tdictionary.
Now I do not know at all where I did something wrong.

type
b=TQueue;
a= TDictionary;
This is correct, since it requires specialization TQueue<ATYTPE> or TDICTIONARY<ATYPE>
Make sure you enable delphi mode, so you don't have to learn the old objfpc generics dialect.

That is correct, I used in the first place
b=TQueue<byte>;
a= TDictionary<byte,byte>;
and got ";" expected but "<" found. So removed all within <> and then there was the message identifier not found.

I think you are mixing up mode delphi and mode objfpc.
Mode objfpc (default, als, in Lazarus) has a very different syntax for generics.

Specialize a type, not a var.

Or it finds the contnrs versions. Remove contnrs from the uses.

Ops.. my mistake
So I removed "contnrs" from the uses in Unit1
and put
unit Unit1;
{$MODE DELPHI}{$H+}
and now all works
only I did not expect to have so much trouble
