class foo {
public:
template<typename T>
foo(int i) : j(i) {}
template<typename T>
void bar(int i) { j = i; }
template<typename T>
static
void baz(int i) {}
int j;
};
int main() {
foo::baz<bool>(3);
foo* p; p->bar<bool>(3);
new foo<bool>(3);
return 0;
}
gets you:
~/ootbc/chips$ g++ foo.cc
foo.cc: In function âint main()â:
foo.cc:8: error: âfooâ is not a template
foo.cc:8: error: no matching function for call to âfoo::foo(int)â
foo.cc:1: note: candidates are: foo::foo(const foo&)
The problem is that the constructor was declared as a template, hence cannot be
called (see bug# 29008). This can be detected at the declaration and a warning
should issue.
OK.
