當構建點雲庫時，g ++對符號'__cxa_free_exception @@ CXXABI_1.3'的未定義引用

Question

構建點雲庫時存在相當多的問題。我運行的是Ubuntu，我有3個版本的GCC和Clang（可能是問題出在哪裏）。我試圖使用與Ubuntu捆綁在一起的g ++ 4.6來構建PCL，因爲它似乎已經獲得了我嘗試過的最遠編譯器。但我有這個問題：

從鏈接器的無效操作是非常奇怪的。有一件事我也想是這樣的：

# include <iostream> 
int main() { 
    std::cout << "Hello, world!\n"; 
} 

其次：

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 

但是，如果我嘗試：

g++ hello.cpp -lstdc++ 

一切都很好。

g++ -v

我很困惑，但我確定它與我目前的g ++設置和我的libstdC++庫有關。我試過易於得到重新安裝，但收效甚微

我只是碰到了這個相同的症狀，和同解（-lstdC++）爲我工作。如果你最近從Ubuntu 12升級到14，或者是升級gcc的東西？

我似乎和this blogger在同一條船上，剛從Ubuntu 12.04升級到14.04。

正如他寫道：

的Ubuntu 14.04使用GCC編譯器和庫的更新版本。這裏的提示是它抱怨核心C++符號：__cxa_free_exception。建議鏈接器與標準C++庫鏈接修復了這個錯誤。您可以通過向鏈接器調用添加-lstdC++來完成此操作。
