这里有您想知道的互联网营销解决方案
addr2line-创新互联
1、符号表 1.1什么是符号表

符号表是内存地址与函数名、文件名、行号的映射表。符号表元素如下所示：

作为一家“创意+整合+营销”的成都网站建设机构，我们在业内良好的客户口碑。创新互联提供从前期的网站品牌分析策划、网站设计、网站建设、成都网站制作、创意表现、网页制作、系统开发以及后续网站营销运营等一系列服务，帮助企业打造创新的互联网品牌经营模式与有效的网络营销方法,创造更大的价值。

<起始地址><结束地址><函数>[<文件名:行号>]

1.2为什么要配置符号表

为了能快速并准确地定位引擎发生Crash的代码位置

举个例子

1.3如何隐藏符号表

如果不额外配置，使用cmake编译出来的so是带符号表的，使用fvisibility=hidden可以隐藏符号表

引擎是在engine-dev/mk/cmake/CMakeLists.txt文件中配置的

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -ffunction-sections -fdata-sections -fvisibility=hidden")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -ffunction-sections -fdata-sections -fvisibility=hidden")

在开启隐藏符号表的情况下，到engine-dev/lib/android/armeabi-v7a目录下看libapp_BaiduMapApplib.so的大小

把engine-dev/mk/cmake/CMakeLists.txt中的隐藏符号表的代码注释掉之后重新编译引擎

可以看到，增加符号表之后的so明显变大了

1.4 查看符号表

在mac系统中可以使用nm命令查看符号表，例如

nm -A libapp_BaiduMapApplib.so

如果想查看是否包含某个方法，可以用grep命令过滤一下，例如

nm -A libapp_BaiduMapApplib.so| grep OnTimerUpdate

可以看到，BaseLayer.cpp文件中包含OnTimerUpdate方法

对于没有符号表的so库使用上边的命令，是没有输出的

2、addr2line

我们经常会遇到地图引擎的crash问题，这个时候就体现出来符号表的作用了，使用addr2line工具，我们可以有效提取出来C/C++层crash的详细信息

首先我们在BaseLayer.cpp中故意插入一段有数组越界的问题代码

VChar chTest[1] = {0};

sprintf(chTest, "house_Ration is %f", house_Ration);

CVLog::Log(CVLog::eLOGError, chTest);

然后在引擎测试工程中运行，触发了crash，关键日志如下

1、确认crash基本信息

Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 11269 (baidumapsdkdemo), pid 11269 (baidumapsdkdemo)

可以看到，是引擎的测试工程发生了crash，导致Crash的是signal 6，关键错误信息是 SI_QUEUE

2、查看backtrace

使用addr2line工具，将日志中的地址定位到具体的代码行

addr工具在NDK/toolchains目录下，记得arm64-v8a用上边的，32位用下边的

addr2line -e ****.so 堆栈信息

这个时候就体现出来符号表的作用了，我们使用不带符号表的release so去反解

因为没有符号表，所以解不出来，接下来用debug的so试一试

直接定位倒问题行号

确实是问题发生的地方

所以在发版的时候，保存一份对应的debug so是很重要的
