Makefile:6: recipe for target 'all' failed
make: *** [all] Error 1

I don't know how can I solve this problem.

this program is worked on VS2017.

but on ubuntu, not working with this problem.

what dose 'makefile:6' mean?

I can't find this on google and stack overflow.....

And, I've heard that it works even with warnings. so I didn't check these warnings.

anyway, please help..

Makefile:6: recipe for target 'all' failed

means, that the target 'all', which is implicitly invoked if no other targets were specified, had errors and that it is defined in your Makefile in line 6.

The underlying error is this linker error:

undefined reference to `CarBST::CarBST()'

This is what you have to fix. The command you use to compile and link is:

g++ -std=c++11 -g -o run NumberNode.cpp LinkedList.cpp CarBST.cpp Queue.cpp CarNode.cpp Manager.cpp main.cpp NumberBST.cpp CarBST.h Queue.h CarNode.h Manager.h NumberBST.h NumberNode.h LinkedList.h

A file CarBST.cpp which presumably contains the class definition is present there, though. It looks like there is no parameterless constructor; either add one to the class or invoke an available constructor.

Furthermore, it is uncommon to specify header files (*.h) at the compiler command line, these are usually included in source files (*.cpp).

And lastly, you should not ignore the warnings and check, why a NULL pointer is assigned to chars. This should probably be

state = 0;

or similar.
