记一次Bug 调试 —— 第三方头文件冲突

记一次Bug 调试 —— 第三方头文件冲突

作者: 蟹蟹宁 | 来源:发表于2021-08-09 00:22 被阅读0次

前言

今天又被Pistche给坑了！
项目中同时使用了WAVM和Pistache两个开源代码，结果两者的头文件定义产生了冲突，导致了大量诡异的错误！

源代码

#include <pistache/common.h>
#include <WAVM/WASM/WASM.h>

int main() {
    return 0;
}

Clion 构建报错信息

可以发现WAVM和pistache都定义了宏函数unreachable，先引入的头文件，覆盖了后引入的头文件，因此WAVM的定义被pistache覆盖了

修复

一、调整头文件顺序
#include <WAVM/WASM/WASM.h>
#include <pistache/common.h>

这种做法治标不治本，因为pistache中比较简单，因此在这里被覆盖不会报错。

但是显然这个方案是不合适的。

二、修改其中之一，化解冲突

我在Pistache的源码上进行了修改，将
#define unreachable() __builtin_unreachable()
替换为
#define UNREACHABLE() __builtin_unreachable()

后记

回过头来看，这个Bug并不像我之前遇到的多线程和内存泄漏Bug那么难定位，只要仔细的看看上图中编译器给出的信息就行了，毕竟是编译错误。

但是当时我看到不下大几十行的报错信息，瞬间就不想看了。。。

于是就根据我的经验，经了漫长的Debug，大概有3、4个小时，最后还是看了报错信息才最终找到了问题所在！

我的第一反应，是不是我构建WAVM的Cmake配置文件不太对，怎么怎么样的，，，反正挺蠢的，毕竟第一次遇到这种问题，以后还是要多看编译器的提示！！！

完整的构建报错信息如下：
