Error Too Many Arguments To Function

Join them; it only takes a minute: Sign up “too many template-parameter-lists” error when specializing a member function up vote 7 down vote favorite I would like to define some template member methods inside a template class like so: template class CallSometing { public: void call (T tObj); // 1st template error too many arguments to function ‘clone’ void call (T tObj, A aObj); // 2nd template template void call (T tObj, A aObj, B bObj); // 3rd }; template void CallSometing::call (T tObj) { std::cout << tObj << ", " << std::endl; } template template void CallSometing::call (T tObj, A aObj) { std::cout << tObj << ", " << aObj << std::endl; } template template template void CallSometing::call (T tObj, A aObj, B bObj) { std::cout << tObj << ", " << aObj << ", " << bObj << ", " << std::endl; } But when instantializing the template class, there is an error concerning the three-argument menthod definition: CallSometing caller; caller.call(12); // OK caller.call(12, 13.0); // OK caller.call (12, 13.0, std::string("lalala!")); // NOK - complains "error: too many template-parameter-lists" Could you please point what I am doing wrong? Why the (2nd) method is OK but the (3rd) causes a compile time error? c++ templates compiler-errors arguments template

Hi :-) I have the following code : the goal is to return a function that is the sum of other functions, roughly. And to learn about variadic templates. #include template struct FSum { FSum(F f) : f_(f) {} ; int operator()() { return f_() ; } F f_ ; } ; template struct FSum { http://stackoverflow.com/questions/35283056/too-many-template-parameters-in-template-redeclaration FSum(F1 f1, F2 f2, Frest... frest) { f_ = f1 ; frest_ = FSum(f2, frest...) ; } int operator()() { return f_() + frest_() ; } F1 f_ ; FSum frest_ ; } ; struct F1 { int operator() () { return 1 ; } ; } ; struct F2 { int operator() () { return 2 ; } ; } ; struct F3 { int operator() () { return 3 ; } ; } ; int main() { F1 f1 ; F2 f2 ; F3 f3 ; FSum fsum = FSum(f1, f2, f3) ; std::cout << fsum() << std::endl ; } But I got the following error message from clang (g++ also gives an error) : test_variadic.cpp:14:1: error: too many template parameters in template redeclaration template ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ And well I don't understand. I though the compiler would choose the class depending on the number of template parameters ? Since the first one has exactly one and the other one has 2 or more. Any idea ? Thanks a lot :-) c++ templates clang variadic share|improve this question asked Feb 9 at 2:44 leo 44628 add a comment| 2 Answers 2 active oldest votes up vote 1 down
