/usr/bin/ld: /tmp/ccIHWHTn.o: in function `Cdisk::Cdisk()‘:编译报错解决方案

问题：C++编译时发现一长串编译报错

$ vim ks.cpp
$ gcc -o ks ks.cpp
报错：
/usr/bin/ld: /tmp/ccIHWHTn.o: in function `Cdisk::Cdisk()':
ks.cpp:(.text+0xb5): undefined reference to `std::cout'
/usr/bin/ld: /tmp/ccIHWHTn.o: in function `Cdisk::~Cdisk()':
ks.cpp:(.text+0x163): undefined reference to `operator delete(void*, unsigned long)'

collect2: error: ld returned 1 exit status
解决：增加编译参数 -lstdc++ 

$ gcc -o ks ks.cpp -lstdc++

编译问题解决，程序正常运行
