在ubuntu'上编译cpp程序时出现问题；贝壳 我尝试了 Linux C++编译器，编译以下代码时发生了： #include <iostream> using namespace std; int main(){ cout<<"Hello World!\n"<<endl; return 0; } ceibal@ceibal:~$ gcc HelloWorld.cpp /tmp/cc78Dkhk.o: In function `main': HelloWorld.cpp:(.text+0xa): undefined reference to `std::cout' HelloWorld.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*)' HelloWorld.cpp:(.text+0x14): 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> >&)' HelloWorld.cpp:(.text+0x1c): undefined reference to `std::basic_ostream<char, std::char_traits<char> >::operator<<(std::basic_ostream<char, std::char_traits<char> >& (*)(std::basic_ostream<char, std::char_traits<char> >&))' /tmp/cc78Dkhk.o: In function `__static_initialization_and_destruction_0(int, int)': HelloWorld.cpp:(.text+0x4a): undefined reference to `std::ios_base::Init::Init()' HelloWorld.cpp:(.text+0x4f): undefined reference to `std::ios_base::Init::~Init()' collect2: ld devolvió el estado de salida 1 ceibal@ceibal:~$ pico HelloWorld.cpp ceibal@ceibal:~$ gcc HelloWorld.cpp HelloWorld.cpp:3:1: error: expected ‘;’ before ‘int’ ceibal@ceibal:~$ pico HelloWorld.cpp ceibal@ceibal:~$ gcc HelloWorld.cpp /tmp/ccIivRal.o: In function `main': HelloWorld.cpp:(.text+0xa): undefined reference to `std::cout' HelloWorld.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*)' HelloWorld.cpp:(.text+0x14): 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> >&)' HelloWorld.cpp:(.text+0x1c): undefined reference to `std::basic_ostream<char, std::char_traits<char> >::operator<<(std::basic_ostream<char, std::char_traits<char> >& (*)(std::basic_ostream<char, std::char_traits<char> >&))' /tmp/ccIivRal.o: In function `__static_initialization_and_destruction_0(int, int)': HelloWorld.cpp:(.text+0x4a): undefined reference to `std::ios_base::Init::Init()' HelloWorld.cpp:(.text+0x4f): undefined reference to `std::ios_base::Init::~Init()' collect2: ld devolvió el estado de salida 1 #包括 使用名称空间std； int main（）{ 库特

这调用C编译器，但是代码是C++的。使用<代码> g++< /C> >调用C++编译器。< /P>

$ g++ HelloWorld.cpp
