basename as your source file; for example, in `allclass.cc', `#pragma implementation' by itself is equivalent to `#pragma implementation "allclass.h"'. Use the string argument if you want a single implementation file to include code from multiple header files. There is no way to split up...

./test.h:17: multiple definition of `gettid()' 正确的用法是使用"inline"或"static inline"修饰一下: inline _syscall0(pid_t, gettid) 或 static inline _syscall0(pid_t, gettid) 当然也可以这样: 在.h头文件中:extern "C" pid_t gettid(void); ...
#include<stdio.h> #defineHELLOWORLD ("hello world\n") intmain(void) { printf(HELLOWORLD); return0; } 使用gcc -E hello.c -o hello.i命令,将 hello.c 文件预处理并且生成 hello.i 目标文件。 之前说道,预处理会将头文件包含进来并且会将宏定义进行替换,因此替换后的 hello.i 文件如下: ...
