Here is the code (nest.cc) that exhibits the error: template<class X> class A { public: class B { public: int i; };
class C: public B { public: void f() { this->i; // OK i; // results in "error: i was not declared in this scope" // even though i should be inherited from B } }; }; This code generate an error when compiled with "g++ -v -save-temps -c nest.cc" on powerpc-linux-gnu using gcc 4.1.2, on i386-redhat-linux using gcc 4.1.0, and on x86_64-redhat-linux using gcc 3.4.5. This is somehow related to the classes being templated because removing the template<class X> line will eliminate the error. It compiles without problem on i386-redhat-linux using gcc 3.2.2, on x86_64-redhat-linux using PGI's pgCC 6.1.6, and on x86_64-redhat-linux using Intel's icc 9.1. -- Summary: inherited members invisible within nested class within templated class Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ghood at psc dot edu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31881
