Similar to what STLport does to pull global functions into std:: //test.cpp - test namespace //global function void testfunc(void){} //pull into namespace namespace myname{ using ::testfunc; }; //use in namespace namespace myname{ void func(void){ testfunc(); // Error: ambiguous reference to symbol } }; int main(void){ myname::func(); return 1; }; output: >sc test.cpp test3 testfunc(); //Error: ambiguous reference to symbol ^ test.cpp(13) : Error: ambiguous reference to symbol Had: testfunc() and: testfunc() --- errorlevel 1 >Exit code: 1 Borland compiles cleanly. >bcc32 test.cpp Borland C++ 5.5.1 for Win32 Copyright (c) 1993, 2000 Borland test.cpp: Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland >Exit code: 0 |

Posted in reply to Tom Lowe | DMC doesn't do the so-called "Koenig lookup" on namespaces. It will, but until then, probably the easiest thing is to use the STL included with DMC.

It will, but until then, probably the easiest thing is to use the STL included with DMC. Was hoping I could use stlport to pull standard functions into std::, just have to wait. Thanks for the reply Tom Lowe talowe@mynetplus.com |
