CentOS6.5系统"libc.so.6: version 'GLIBC_2.15' not found"处理

场景 安装TensorFlow后启动项目index.py时,报错:libc.so.6: version ‘GLIBC_2.15’ not found; 分析 由于glibc版本过低,升级glibc即可。由于CentOS系统RPM源目前glibc最高版本是2.12,所以只能采用源码升级,下载glibc-2.15.tar.gz 1)查看系统glibc支持的版本 strings /lib64/libc.so.6 |grep GLIBC //可看到支持的版本最新是2.12 #查看当前glibc版本 ll /lib64/libc.so.6 lrwxrwxrwx. 1 root root 12 2月 5 2018 /lib64/libc.so.6 -> libc-2.12.so 2)下载glibc源码包(找个可以上网的,比如DMZ区的主机,然后再通过内网传送到目标主机) cd /usr/src/ wget http://mirror.bjtu.edu.cn/gnu/glibc/glibc-2.15.tar.gz wget http://mirror.bjtu.edu.cn/gnu/glibc/glibc-ports-2.15.tar.gz      #glibc插件 3)解压安装升级glibc tar zxvf glibc-2.15.tar.gz tar zxvf glibc-ports-2

什么是 C 和 C ++ 标准库?

佐手、 提交于 2020-01-15 22:26:58
简要介绍编写C/C ++应用程序的领域,标准库的作用以及它是如何在各种操作系统中实现的。 我已经接触C++一段时间了,一开始就让我感到疑惑的是其内部结构:我所使用的内核函数和类从何而来? 谁发明了它们? 他们是打包在我系统中的某个地方吗? 是否存在一份官方的C ++手册? 在本文中,我将通过从C和C ++语言的本质到实际实现来尝试回答这些问题。 C和C++是如何制订的 当我们谈论C和C++时,实际上是指一组定义(程序)语言应该做些什么,如何表现,应该提供哪些功能的规则。C/C++的编译器为了处理C/C++编写的源代码必须跟随着这些规则,并生成二进制应用程序。听起来非常接近于HTML:浏览器遵循着一组指令,所以它们可以以明确的方式来渲染网页。 与HTML一样,C和C++的规则都是理论上的。 国际标准化组织 (ISO)的一大群人每年都会聚集几次来讨论和定义语言规则。没错,C和C++是标准化的东西。他们最终都会得到一本官方的叫标准的书,你可以从他们的网站中购买。随着语言的发展新的papers(指官方的叫标准的书)会被发布,每一次都定义一个新的标准。这就是为什么我们会有不同的C和C++版本的原因:C99, C11, C++03, C++11, C++14等等,数字与出版/发布年份相符。 Tot_ziens 翻译于 4周前 2人顶 顶 翻译得不错哦! 这些标准都市非常详细和有技术新的文档

clock_gettime() still not monotonic - alternatives?

痴心易碎 提交于 2020-01-15 09:01:14
问题 As has been known for a while (see, e.g., this old question, and bug reports that pop when you google this), clock_gettime() doesn't appear to report back time monotonically. To rule out any silly error I might have overseen, here is the relevant code (excerpt from larger program): <include time.h> long nano_1, nano_2; double delta; struct timespec tspec, *tspec_ptr; clock_gettime(CLOCK_MONOTONIC_RAW, tspec_ptr); nano_1 = tspec.tv_nsec; sort_selection(sorted_ptr, n); clock_gettime(CLOCK

Why inet_ntoa is designed to be a non-reentrant function?

半世苍凉 提交于 2020-01-12 07:48:11
问题 Glancing at the source code of GNU C Library,I found the inet_ntoa is implementated with static __thread char buffer[18] My question is, since there is a need to use reeentrant inet_ntoa,why do not the author of GNU C Library use malloc to implementate it? thanks. 回答1: The reason it's not using the heap is to conform with standards (POSIX) and other systems. The interface is just not such that you are supposed to free the buffer returned. It assumes static storage.. But by declaring it as
