Circular Inclusion with Templates

Question

The following code compiles perfectly:

// MyFile.h

#ifndef MYFILE_H_INCLUDED
#define MYFILE_H_INCLUDED

template 
class MyClass
{
          


        

Answer 1

• Rename the file "MyFile.cpp" to "MyFile.tpp".
• Remove the include guards from "MyFile.tpp"
• Change the include in "MyFile.h" so it is "MyFile.tpp"
• Remove the the include inside "MyFile.tpp"

Note: Because the file is a *.tpp file (not *.cpp) it should not be included by other build system operations. If you have added it manually remove it.

Make sure the only place that includes .tpp is the last line in .h
