[cfe-dev] clang cannot find standard template library

[Pål Dahle]

Hi.

Looking for an alternative to g++, I have stumbled across
clang. And, impressively, clang has managed to compile my
C++ code consisting of some 80 000 lines of code.

However, when it comes to linking, things stop. It seems
that clang does not find the standard template library.

As a matter of fact, even the trivial

#include <iostream>
int main () { std::cout << "Hello world." << std::endl; }

ends it's compilation with the following error message:

nebuchadnezzar:/opt/project/Cohiba/trunk/cohiba/tmp$ clang test.cpp
/tmp/cc-jpZ3sj.o: In function `__cxx_global_var_init':
test.cpp:(.text+0x18): undefined reference to `std::ios_base::Init::Init()'
test.cpp:(.text+0x20): undefined reference to `std::ios_base::Init::~Init()'
/tmp/cc-jpZ3sj.o: In function `main':
test.cpp:(.text+0x63): undefined reference to `std::cout'

[snip]

Can anyone give me a hint where to look? I have tried
the manual pages, but that didn't bring me any further.

By the way, I'm using the clang provided bu Ubuntu 10.04

Best regards
Pål
