.h file and .cxx file?

ROOT
1

Hi, my teacher has given me two files, one .h and the other one .cxx.

In the first one he creates a library and declares the methods that he will use.

In the .cxx one he wrote what the methods, constructors do.

How can I run them from cmd?

First write .L namefile.h and then .x namefile.cxx ? I obtain errors with this method

I use root 6 on Windows 10 with visual studio 2019

.x namefile.cxx

Should be enough. What errors do you get ?

I have tried and I have this error:

IncrementalExecutor::executeFunction: symbol '?GenerateInitInstance@ROOT@@YAPAVTGenericClassInfo@1@PBVMyClass@@@Z' unresolved while linking function '??__Eid@?$num_put@DV?$ostreambuf_iterator@DU?$char_traits@D@std@@@std@@@std@@2V0locale@2@A@YAXXZcling_module_9_'!
You are probably missing the definition of class ROOT::TGenericClassInfo * __cdecl ROOT::GenerateInitInstance(class MyClass const *)
Maybe you need to load the corresponding shared library?

Why don’t you ask your “teacher” how you’re supposed to use his/her files?

Because I don’t see him till friday, if you want to help me good otherwise bye bye

It is really difficult to help you. We even do not have your code …

I’m only trying to create a class in which I define .h file with declaration of methods and a .cxx file (or a .cpp file?) for implementation.

This is the header file (an example)

MyClass.h (959 Bytes)

and then a .cxx file for implementation but when I write on it :

#include "MyClass.h"

and try to run it the cmd says me:

IncrementalExecutor::executeFunction: symbol '??0MyClass@@QAE@XZ' unresolved while linking [cling interface function]!
You are probably missing the definition of public: __thiscall MyClass::MyClass(void)
Maybe you need to load the corresponding shared library?

but the same thing doesn’t happen if I write in cmd: #include “MyClass.h”

You can try:
.L MyClass.cxx
and / or:
.L MyClass.cxx++

@Wile_E_Coyote Thank you for the answer.

No errors with .L MyClass.cxx, why? why does in my case .x MyClass.cxx give error?

Moreover, where have I to put the .h file? I have put it everywhere (in the macros folder, in the folder include of visual studio and root)
