C++ template working fine for GCC but showing compile time error in LLVM-GCC compiler

开发者 https://www.devze.com 2023-04-12 06:18 出处:网络
typedef char TCHAR; template <class T&g开发者_C百科t; class MyTemplateString { }; template <class T> class MyList
typedef char TCHAR;

template <class T&g开发者_C百科t; class MyTemplateString
{

};
template <class T> class MyList
{

};
typedef MyTemplateString<TCHAR>         MyString;

MyList<MyString> outlist;// here it's showing compile time error

The error is:

Implicit instantiation of undefined template MyList <MyTemplateString<char>>

Works fine with GCC compiler only but does not work in LLVM-GCC compiler.


The code as posted above compiles fine here without any errors or warnings using both g++ and llvm-g++:

$ g++ -Wall -c template.cpp 

$ llvm-g++ -Wall -c template.cpp

My guess is that your real problem lies elsewhere.
