It has nothing to do with difference between "" and <> Simply predeclare "using namespace std;" when you use #include <iostream> -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of Crescioli, Phil Sent: Thursday, January 29, 2004 11:22 AM To: gcc-help@xxxxxxxxxxx Subject: gcc323 and gcc332 101 Hello, I've created a very basic test routine to start my own unique testing of a gcc323 and gcc332 install using c++ that I have recently placed in separate dirs in my NFS mounted home account on a solaris 8 box. Using c++ I get it to build and run but am having errors using #include<iostream>. Any replies are appreciated. //#include "iostream.h" //#include <iostream.h> #include <iostream> int main(void) { cout << "main() reporting that GCC compiled this ok" << endl ; return (0); } /* main */ I get it to build using #include <iostream.h> or #include "iostream.h" but am warned with the following message: [langley]:/home/philc/GCC/test>g++ -o test2 test2.cpp In file included from [langley]:/home/philc/GCC/test>g++ -o test2 test2.cpp In file included from /home/philc/GCC/gcc323bin/include/c++/3.2.3/backward/iostream.h:31, from test2.cpp:2: /home/philc/GCC/gcc323bin/include/c++/3.2.3/backward/backward_warning.h: 32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated. I cannot get it to build using #include <iostream>. I get the following compile time error: [langley]:/home/philc/GCC/test> g++ -o test2 test2.cpp test2.cpp: In function `int main()': test2.cpp:6: `cout' undeclared (first use this function) test2.cpp:6: (Each undeclared identifier is reported only once for each function it appears in.) test2.cpp:6: `endl' undeclared (first use this function) I though I understood the "" and <> meaning until now...
