breakpad尝试

何为breakpad：

　　如果你的程序是C++程序，crash的时候无所适从，那么你可以考虑使用一下看看

https://blog.csdn.net/fengyulinde/article/details/81707346

1
准备：
库，代码，编译好

./configure && make

make中要是报错：
头文件linux_syscall_support.h，该头文件要放在src hird_partylss目录下，其中lss目录要自己建

make install

install后下面
/usr/local/include/
/usr/local/lib/

libbreakpad.a
libbreakpad_client.a

2.
库集成到自己的工程：

头文件：
#include "client/linux/handler/exception_handler.h"
#include "third_party/lss/linux_syscall_support.h"
#include "client/linux/handler/minidump_descriptor.h"

捕捉函数：
static bool dumpCallback(const google_breakpad::MinidumpDescriptor& descriptor,
void* context,
bool succeeded)
{
std::cout << "Dump path:" << descriptor.path() << std::endl;
return succeeded;
}

程序开始加入捕捉
int main(int argc, char *argv[])
{
google_breakpad::MinidumpDescriptor descriptor("/srv/log");
google_breakpad::ExceptionHandler eh(descriptor, nullptr, dumpCallback, nullptr, true, -1);

IgnoreSignals();
setCorDump();
......
}

3.
编译工程会报错：
"inttypes.h has already been included before this header file, but
without __STDC_FORMAT_MACROS defined"

查看源文件：
breakpadincludegoogle_breakpadcommonreakpad_types.h

注释掉后，编译成功

集成完成，出现crash，开发执行分析：

1. gen sym files：

dump_syms ./test-server > test-server.sym
dump_syms /usr/lib/debug/lib/x86_64-linux-gnu/libc-2.31.so > libc-2.31.so.sym

2. 组织好symbols目录结构,结构必须严格，否则最后读不到符号文件

$ head -n1 test-server.sym
MODULE Linux x86_64 1B84C720DE19E3AE62EADD07379DA3F90 test-server

-symbols（一级目录，别的什么目录下无所谓）
-----app(二级目录，如：test-server)
   --------id(三级目录，如：1B84C720DE19E3AE62EADD07379DA3F90）
       ------------files:（四级文件：如：test-server.sym ）
-----so1
      xxx

如：
symbols
--test-server

--libc-2.31.so

3. 生成crash的log
sudo minidump_stackwalk /srv/log/8b268c24-eb30-4f24-4da6609d-234c1a05.dmp ./symbols > error.1.log

4. 查看crash生成的log，定位crash的行数

对比crash的代码，很遗憾，最终还是无法看见详细的堆栈已经crash的点，不知道是不是库集成问题，亦或是之前编译报错强行注释掉解决编译问题导致
具体原因暂未可知。。。。。。
由于项目时间紧，暂时放弃集成使用，暂留做记录，以便后续继续研究
