From: "igodard at pacbell dot net" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/29427] New: uncallable constructor template should be warned. Date: Wed, 11 Oct 2006 05:36:00 -0000 [thread overview] Message-ID: <bug-29427-6594@http.gcc.gnu.org/bugzilla/> (raw) [-- Warning: decoded text below may be mangled, UTF-8 assumed --] [-- Attachment #1: Type: text/plain, Size: 1117 bytes --] 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. -- Summary: uncallable constructor template should be warned.
