Gcc Error Non-template Used As Template

Without this space, the C++98/C++03 compiler would see a >> (right-shift) token instead of two >'s. Because of that, in the C++11 standard, the export feature has been removed from the language.

Suppose you have a template Foo defined like this: template class Foo { public: Foo(); void someMethod(T x); private: T x; }; Along with similar definitions for the member functions: http://stackoverflow.com/questions/12959250/why-am-i-getting-the-error-non-template-f-used-as-template Class D is still derived from class B, the compiler still lets you implicitly do the is-a conversions (e.g., D* to B*), dynamic binding still works when virtual functions are invoked,

It causes a problem for operator+ because that clashes with the name of a member function, so the hint is right but not sufficient to tell you how to make the https://gcc.gnu.org/bugzilla/show_bug.cgi?id=29469 Join them; it only takes a minute: Sign up G++ Compiler Error or faulty code? : “template definition of non-template” up vote 10 down vote favorite As part of a traits Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file? Otherwise the name is assumed to name a non-template. 1 @Johannes has written a very good explanation here: Where and why do I have to put "template" and "typename" on dependent

The compiler will automagically select the correct specialization when it sees which T you are using. What's behind the word "size issues"? The other solution is to leave the definition of the template function in the .cpp file and simply add the line template void foo(); to that file: // File "foo.cpp" #include Unsubstantiated With the passing of Thai King Bhumibol, are there any customs/etiquette as a traveler I should be aware of?

How can I create a container-template that allows my users to supply the type of the underlying container that actually stores the values? Is there a Korean word for 'Syllable Block'? Comment 13 Jonathan Wakely 2012-04-12 12:44:13 UTC Are any of the examples in this PR actually valid? Yet another way to say, "class templates." Not to be confused with "generality" (which just means avoiding solutions which are overly specific), "genericity" means class templates.

How can I avoid linker errors with my template functions?

Workarounds: Change the call from f() to this->f(). Consider a container class Array that acts like an array of integers: // This would go into a header file such as "Array.h" class Array { public: Array(int len=10) : len_(len), Bug10710 - ICE (segault) after "error: non-template used as parameter" Summary: ICE (segault) after "error: non-template used as parameter" Status: RESOLVED FIXED Alias: None Product: gcc Classification: Unclassified Component: c++ (show Comment 9 Joseph S.

And that is DR 224 which is in WP. Within D::g(), the name f does not depend on template parameter T, so f is known as a nondependent name. I'm wondering whether this change was intentional and whether there's a good reason for this change (in a stable branch). $ g++-4.1 -c pair.c x.c:32: error: non-template 'pair' used as template How?

What are oxidation states used for? foo_part(x); // ... Why does argv include the program name? This is a quality-of-implementation issue so your results may vary.

The C++ keyword export was originally designed to eliminate the need to include a template definition (either by providing the definition in the header file or by including the implementation file). Class templates are often used to build type safe containers (although this only scratches the surface for how they can be used). In case of conflict (when some template specialization matches the non-template function signature exactly), use of that name and type refers to the non-template member unless an explicit template argument list One of several ways I personally use template specialization is for stringification.

If the types do not match exactly, the conversions are not considered and the template is simply dropped from the set of viable functions.

Tell your C++ compiler which instantiations to make while it is compiling your template class's .cpp file. (If you've already read the previous FAQ, this answer is completely symmetric with that Privacy policy About cppreference.com Disclaimers If those answers do not fully address your question, please ask a new question. Finding good names for constraints can be hard.

They might require an extra microsecond to compile, but once all the types are resolved by the compiler, the resulting code is just as fast as if you used them directly Ah, the intricacies of template friends. Maybe g++ is correct to reject them, but the diagnostics printed are awful.
