I have a lot of problems with creating the Point Cloud Library. I am running Ubuntu and I have 3 versions of GCC and Clang (probably where the problem is). I'm trying to use g ++ 4.6, which comes bundled with Ubuntu, to build PCL, as it seems to have got the farthest of the compilers I tried. However, I have this problem:

The invalid linker operation is really strange. One thing I tried also was the following:
# include <iostream> int main() { std::cout << "Hello, world!\n"; }
The following are:
g++ hello.cpp /tmp/cc29vkpU.o: In function `main': hello.cpp:(.text+0xa): undefined reference to `std::cout' hello.cpp:(.text+0xf): 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*)' /tmp/cc29vkpU.o: In function `__static_initialization_and_destruction_0(int, int)': hello.cpp:(.text+0x3d): undefined reference to `std::ios_base::Init::Init()' hello.cpp:(.text+0x42): undefined reference to `std::ios_base::Init::~Init()' collect2: ld returned 1 exit status
However, if I try:
g++ hello.cpp -lstdc++
things are good.
g++ -v Using built-in specs.

Im quite confused, but I'm sure this is due to my current g ++ installation and my libstdC ++ library. I tried apt-get reinstall, but with little success
