on running this program on some linux versions, it does not compile

bcc test.cpp

what versions?!

---------------------------------------
#include <iostream.h>
using namespace std;
int main()
{
std::cout <<"test";
return 0;
}

---------------------------------

iostream.h is non-standard.

#include <iostream>

There's no std::cout in iostream.h - that's the error...

any suggestions
thanks

bcc test.cpp

Huh?? I hope you meant gcc. And you have to use g++ to compile C++ -
not gcc.

Not technically true. You can do gcc test.cpp -lstdc++

But if you use g++, it will add the std c++ library for you.

------------------------------ test.cc ------------------------------
#include <iostream>

int main() {
std::cout << "Hello World!\n";

return 0;
}
---------------------------------------------------------------------

gcc is no good:

$ gcc test.cc
/tmp/cc3RNzo4.o(.text+0x19): In function `main':
: undefined reference to `std::cout'
/tmp/cc3RNzo4.o(.text+0x1e): In function `main':
: undefined reference to `std::basic_ostream<char,

>(std::basic_ostream<char, std::char_traits<char> >&, char const*)'

/tmp/cc3RNzo4.o(.text+0x4a): In function
`__static_initialization_and_destruction_0(int, int)':
: undefined reference to `std::ios_base::Init::Init[in-charge]()'
/tmp/cc3RNzo4.o(.text+0x79): In function `__tcf_0':

/tmp/cc3RNzo4.o(.eh_frame+0x11): undefined reference to
`__gxx_personality_v0'
collect2: ld returned 1 exit status

but, this works just fine

$ gcc test.cc -lstdc++

Of course, since he didn't add that -lstdc++ line, it's would probably fail.

I did not know about this. Thanks John.
