在C++代码中调用C的库文件,需加上extern "C",用来告知编译器:这是一个用C写成的库文件,请用C的方式连接他们。 Undefined reference to 错误:这类错误是在连接过程中出现的,可能有两种原因∶ 一是使用者自己定义的函数或者全局变量所在源代码文件,没有被编译、连接,或者干脆还没有定义,这 需要使用者根据实际情况...

下面显示的是首先直接用g++编译main.cpp,出现了"undefined reference to foo()"的问题,未能编译出可执行程序a.out;然后在编译命令行加上foo.cpp(foo函数的定义文件)后,成功编译出a.out,而且执行起来更是非常顺滑～ + 1.2 缺目标文件。同样,首先把foo.cpp编译成目标文件foo.o之后,也可以用foo.o来编译,也可以...
