问题描述
我需要在大约300 .c文件顶部包括的#define
。我想preFER不改变code作为它是开源的code,但如果我有,我会只写一个脚本来修改的所有文件。有没有使用gcc添加方式的#define
或头文件包括编译过程中每一个源文件的顶部?在的#define
是这样的:
#定义的malloc MYmalloc
您可以通过 -Dmalloc = MYmalloc
到 GCC
选项。
有关 -D
选项的详细信息:

请注意,如果要修改的malloc
函数的行为出于调试的目的,你也可能有兴趣在的glibc
的malloc
挂钩:

I need to include a #define
at the top of around 300 .c files. I would prefer not to change the code as it is open source code but if I have to I will just write a script to modify all the files. Is there a way using gcc to add a #define
or header file include to the top of every source file during compilation? The #define
is this:
#define malloc MYmalloc
You can pass -Dmalloc=MYmalloc
to the gcc
options.
For more information about the -D
option:

Note that if you want to modify the behavior of malloc
function for debugging purposes, you may also be interested in glibc
malloc
hooks:

这篇关于包括在编译的时候在所有的.c源文件的#define的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
