使用log4cpp 出现coredump

lovzm 2017-04-27 03:45:24
问题介绍：
环境 gcc4.9.2 centos6.4 使用了boost库 log4cpp库；
可以肯定与boost库无关！

用log4cpp的初始化了一个写入file的句柄；
并调用log4cpp::Category 的info方法：
log4cpp::Category& m_category_ref = log4cpp::Category::getRoot();

log4cpp::PatternLayout *pattern_two =

		new log4cpp::PatternLayout;

	pattern_two->setConversionPattern("%d: %p %c %x:%m%n");

log4cpp::FileAppender *file_appender =

		new log4cpp::FileAppender("fileAppender", “2017_4_27.log”);

	file_appender->setLayout(pattern_two);



	m_category_ref.setPriority(log4cpp::Priority::DEBUG);

	m_category_ref.addAppender(file_appender);

std::ostringstream os;

os << "file created";

m_category_ref.info(os.str());

m_category_ref.info(os.str());[size=16px] //调用该句：出现如下段错误！

在windows平台可以编译通过，并且正常~
在Linux平台出现段错误，请问如何分析解决问题！

引用 3 楼 lsyyff23 的回复:
谢谢 赵4老师 那个问题，经过多番尝试，以及调试，引出其他问题， 在某个帖子上看到 加个 -lstdc++ 就可以了~ 另外我也升级了GCC 到 最新版本，是否是这个也未尝知道，还待尝试！
你能记住“尺有所短，寸有所长。”这句话我就夫复何求了。

不清楚为什么。不过可以试试boost::log库，比log4cxx好很多。

建议改用我这个土造MyLog：
//循环向a函数每次发送200个字节长度（这个是固定的）的buffer,
//a函数中需要将循环传进来的buffer，组成240字节（也是固定的）的新buffer进行处理，
//在处理的时候每次从新buffer中取两个字节打印

Linux GDB C/C++调试 从入门到精通
这是关于Linux C/C++ gdb调试课程，主要介绍Linux gdb C/C++调试基本知识，...尤其是一些高级知识，比如内存问题，死锁问题，崩溃问题，core dump分析， 软件密码“破解”等等，一定会让你受益匪浅！    
log4cpp和muduo
注意log4cpp的性能较为一般，不建议在服务器中使用，但是代码可读性较好。log4cpp支持多种输出：网络、本地文件、控制台。而muduo日志库支持的功能不多，但性能较log4cpp好。这里介绍的目的，主要是⽤来分析⼀个⽇志...

Android coredump生成与APK调试
但是Linux下就可以用gdb 来调试coredump，那么Android应该也可以才对。 关于Linux下Coredump调试可以参考这篇文章： Linux coredump 调试 然后我按照Linux的方法设置了ulimit -c 和 coredump生成位置。结果，根本就...
