undefined reference to `std::basic_ostream<...

[Andreas Schmidt]

I have a simple hello world program, but it does not compile:

/tmp/cc0IGuxk.o(.text+0x14): In function `main':
: undefined reference to `std::basic_ostream<char, std::char_traits<char>
>& std::endl<char, std::char_traits<char> >(std::basic_ostream<char,
std::char_traits<char> >&)'
/tmp/cc0IGuxk.o(.text+0x21): In function `main':
: undefined reference to `std::cout'
/tmp/cc0IGuxk.o(.text+0x26): In function `main':
: undefined reference to `std::basic_ostream<char, std::char_traits<char>
>& std::operator<< <std::char_traits<char> >(std::basic_ostream<char,
std::char_traits<char> >&, char const*)'

... and so on.

I suspect this is just a path problem?

Also, I had to compile it with -I because otherwise it would not find a
lot of h files:
gcc -I/usr/include/g++/i586-suse-linux /tmp/helloworld.cpp

How can I add /usr/include/g++/i586-suse-linux
to the standard paths to look for h files?

The reason for all this mess is that I had replaced some gcc3.3.23 rpms
with gcc3.3.43 rpms, but probably I forgot to update some of them, and so
I got the chaos. Now I copied all 3.3.23 files back, and have these path
issues described above.

Does anyone know how to solve this?

Thanks, Andi

Oh yes it does. What it doesn't do is link (linking and compilation
are separate steps).

It isn't. It's a problem of using incorrect compiler front end.
You are obviously compiling C++, you should use g++ for it.

Same solution: use 'g++' instead of 'gcc'.

Oh, I thought they are equvalent, I'm sorry. Anyway, I tried both, and
g++ always gives me this:

/usr/lib/gcc-lib/i586-suse-linux/3.3/../../../libstdc++.a(eh_throw.o)(.text.__cxa_rethrow+0x48):
In function `__cxa_rethrow':
: undefined reference to `_Unwind_Resume_or_Rethrow'

(see earlier posting from Nov 27)

But I don't care anymore, I am anyway updating my complete OS now... :)

That is a common misconception.
The differences are quite significant, both at compile and at link time.
