I'm struggling with the syntax for the case where I have a template http://stackoverflow.com/questions/11394832/how-to-define-a-template-member-function-of-a-template-class member function within a template class: template class Foo { void Bar(const T * t); template void Bar(const T2 * t); }; template void Foo::Bar(const T * t) { // ... no problem ... } template void Foo::Bar(const T2 * t) { // ... this is where I'm tearing my hair out ... } The first member function is fine, but the template member function which handles types other than the base type of the template class is where I am having problems. For the above case I get the following errors: template_problem.cpp:12: error: parse error in template argument list template_problem.cpp:12: error: expected ‘,’ or ‘...’ before ‘*’ token template_problem.cpp:12: error: ISO C++ forbids declaration of ‘T2’ with no type template_problem.cpp:12: error: template-id ‘Bar< >’ in declaration of primary template template_problem.cpp:12: error: prototype for ‘void Foo::Bar(int)’ does not match any in class ‘Foo’ template_problem.cpp:4: error: candidates are: template template void Foo::Bar(const T2*) template_problem.cpp:7: error: void Foo::Bar(const T*) template_problem.cpp:12: error: template definition of non-template

Code template class SomeClass; class Class; SomeClass<::Class>* cls; c++ parsing templates c-preprocessor digraphs share|improve this question edited Aug 22 '14 at 19:13 Shafik Yaghmour 101k19232330 asked Oct 17 '10 at 9:14 Pirate 813 1 The new standrard (C++0x) addresses the issue of >> like in A>. Doesn't it address this issue as well? Incidentally, Micorosoft compilers don't give c++ template member error on this (I know that they technically should, but it's good they don't) –Armen Tsirunyan Oct 17 '10 at 9:59 @ArmenTsirunyan yes, this was fixed in C++0x which became C++11 although the fix for >> was done in section 14.3 which is different than the fix for <:: which is a modification of the maximal much rule. So both annoying but different core issues at work. I detail this in my answer. –Shafik Yaghmour Jul 27 '14 at 2:30 add a comment| 4 Answers 4 active oldest votes up vote 32 down vote According to the Maximal Munch tokenization principle a valid C++ token must collect/have as many consecutive characters as possible. <: is a digraph (an alternative representation of symbol [). Digraph Equivalent <: [ :> ] <% { %> } %: # So SomeClass<::Class>* cls; is interpreted as SomeClass[:Class>* cls; which doesn't make any sense. Solution: Add a whitespace between < and : SomeClass< ::Class>* cls; ^ | White Space share|improve this answer edited Oct 17 '10 at 9:22 answered Oct 17 '10 at 9:15 Prasoon Saurav 58.5k29199312 add a comment| up vote 11 down vote Try the following instead: SomeClass< ::Class>* cls; You can find more info in this question about digraphs.
