• 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).
  
• 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.
• 
  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.
