From: ronny@mit.edu To: gcc-gnats@gcc.gnu.org Subject: c++/7345: parse error when using templated member function from templated base class Date: Wed, 17 Jul 2002 12:46:00 -0000 [thread overview] Message-ID: <20020717194527.25853.qmail@sources.redhat.com> (raw) >Number: 7345 >Category: c++ >Synopsis: parse error when using templated member function from templated base class >Confidential: no >Severity: serious >Priority: medium >Responsible: unassigned >State: open >Class: rejects-legal >Submitter-Id: net >Arrival-Date: Wed Jul 17 12:46:00 PDT 2002 >Closed-Date: >Last-Modified: >Originator: Ronny Krashinsky >Release: gcc version 3.0.4 >Organization: >Environment: x86, linux >Description: compiling this program: ----------------------------------------------------- //#include<stdio.h> template<int x> class A { public: template<int y> int foo() { return (x + y); }; int foo2() { return foo<2>(); }; }; template<int x> class B : public A<x> { public: int bar() { return ( foo<2>() ); }; }; int main() { int i; A<3> a; i = a.foo<2>(); //printf("%d\n", i); i = a.foo2(); //printf("%d\n", i); B<3> b; i = b.bar(); //printf("%d\n", i); return(0); }; ----------------------------------------------------- results in this parse error: ----------------------------------------------------- bug.cc: In member function `int B<x>::bar()': bug.cc:16: parse error before `;' token ----------------------------------------------------- I think that the compiler is not recognizing foo<2> as the name of a function as it should. I don't know of any workaround to call foo<2> from within B. "A::foo<2>()" doesn't work, "using A::foo<2>" doesn't work, declaring a function pointer doesn't work, etc. >How-To-Repeat: compile the program >Fix: >Release-Note: >Audit-Trail: >Unformatted: ----gnatsweb-attachment---- Content-Type: application/octet-stream; name="bug.cc" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="bug.cc" Ly8jaW5jbHVkZTxzdGRpby5oPgoKdGVtcGxhdGU8aW50IHg+CmNsYXNzIEEgewpwdWJsaWM6CiAg dGVtcGxhdGU8aW50IHk+CiAgaW50IGZvbygpIHsgcmV0dXJuICh4ICsgeSk7IH07CiAgaW50IGZv bzIoKSB7IHJldHVybiBmb288Mj4oKTsgfTsKfTsKCgp0ZW1wbGF0ZTxpbnQgeD4KY2xhc3MgQiA6 IHB1YmxpYyBBPHg+IHsKcHVibGljOgogIGludCBiYXIoKSB7IAogICAgcmV0dXJuICggZm9vPDI+ KCkgKTsKICB9Owp9OwoKCmludCBtYWluKCkgewogIGludCBpOwogIEE8Mz4gYTsKICBpID0gYS5m b288Mj4oKTsKICAvL3ByaW50ZigiJWRcbiIsIGkpOwogIGkgPSBhLmZvbzIoKTsKICAvL3ByaW50 ZigiJWRcbiIsIGkpOwoKICBCPDM+IGI7CiAgaSA9IGIuYmFyKCk7CiAgLy9wcmludGYoIiVkXG4i LCBpKTsKCiAgcmV0dXJuKDApOwp9OwoKCgoKCg==
