title: g++ undefined reference to symbol '__cxa_free_exception@@CXXABI_1.3' when building Point Cloud Library
body: <p>Im having quite a few problems building the Point Cloud Library. I am running Ubuntu and I have 3 versions of GCC and Clang (probably where the problem is). Im trying to use g++ 4.6 that comes bundled with Ubuntu in order to build PCL as it seems to have gotten the farthest of the compilers I've tried. However I have this problem:</p>

  <p>Invalid Operation from the Linker is really odd. One thing I tried also was this:</p>
  
  <pre><code># include &lt;iostream&gt;
  int main() {
    std::cout &lt;&lt; "Hello, world!\n";
  }
  </code></pre>
  
  <p>Followed by:</p>
  
  <pre><code>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&lt;char, std::char_traits&lt;char&gt; &gt;&amp; std::operator&lt;&lt; &lt;std::char_traits&lt;char&gt; &gt;(std::basic_ostream&lt;char, std::char_traits&lt;char&gt; &gt;&amp;, 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

  <p>However if I try:</p>
  
  <pre><code>g++ hello.cpp -lstdc++
  </code></pre>
  
  <p>all is well. </p>
  
  <pre><code> g++ -v
  Using built-in specs.

  <p>Im quite confused but Im sure its something to do with my current g++ setup and my libstdc++ library. I've tried apt-get reinstall but with little success</p>
  
  <p>Cheers</p>
