[c++] lokatie van libraries

[Reefer]

ik heb gcc 3.0.3 geinstalleerd , maar nou kreeg ik errors van iostream.h over bepaalde nietbestaande functies. En toen ging ik eens kijken naar welke file ik moest hebben, alleen ik kreeg dit :

code:

[root@linux reefer]# locate ostream.h
/usr/include/g++-3/iostream.h
/usr/include/g++-3/ostream.h
/usr/include/g++-3/stdiostream.h
/usr/include/iostream.h
/usr/include/ostream.h
/usr/include/stdiostream.h
/usr/include/g++/iostream.h
/usr/include/g++/ostream.h
/usr/include/g++/stdiostream.h
/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.3/iostream.h
/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.3/ostream.h
/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.3/stdiostream.h

welke libraries worden nou gebruikt worden bij het compilen?

euhm volgens mij hoef je daar niet eens te zoeken, wat was dan precies de error die je kreeg?

[Reefer]

dit is de error, ik heb gcc 3.0.3 geinstalleerd via een tarball...is dat mis gegaan denk ik

code:

         return 0; }

Kun je niet gewoon overstappen op <iostream> ?
<iostream.h> is een niet-standaard header, daar mag je verwachten dat er bepaalde std:: namen missen.

code:

#include <iostream.h>

int main() { cout << "Hello cruel world"<< endl; 
         return 0; }

#include <iostream> is correct in dit geval, en de correcte regel voor compilatie :

g++ -o blaat blaat.cpp
