• Stubs for C++ templates are supported for the following compilers:
  • GNU GCC 5.x or newer
    
  • Clang C/C++ Compiler 5 or newer
    
  • Microsoft Visual C++ 14.1 (2017) or newer
• Stubs for C++ templates are not supported for:

  • Constructors and destructors

  • Conversion operators

  • Implicitly defined functions

  • Defaulted and deleted functions

  • Friend functions

• To use stubs for C++ templates, all template argument types must be defined before the original template definition (in all translation units where the instance is created).
  
  Example of code where stubs for templates cannot be used:
  

  Code Block
  // = from func.h // "S" type (used in instance below) is unknown template <typename T> void func(T t) {} // = from struct.h struct S {}; // stub for func<S>(S) cannot be used void m(S s) { func(s); // call to be stubbed }

  
  To enable stubs for templates, the code can be changed to:

  Code Block
  // = from struct.h // Type S defined before template function definition struct S {}; // = from func.h // "S" type (used in instance below) is defined template <typename T> void func(T t) {} // stub for func<S>(S) can be used void m(S s) { func(s); // call to be stubbed }

  
  Depending on the situation you might need to change the order, structure or content of the include files.
  
  
• Stubbing C++ template explicit/full specializations is possible regardless of whether C++ template stubs functionality is enabled.
  Stubbing explicit/full specializations that are class methods is not supported.
