GLIBC_2.xx not found(GLIBC升级)

纵然是瞬间 提交于 2020-02-01 20:47:01
系统默认一般是2.12.我在centos上运行chromedriver的时候报了glibc_2.14和2.16没找到,所以要升级.下面是参考文档: 场景需求 默认的Centos6.5 glibc版本最高为2.12, 而在进行Nodejs开发时项目所依赖的包往往需要更高版本的glibc库支持, 因此在不升级系统的前提下, 需要主动更新系统glibc库. 一般遇到错误 libc.so.6: version GLIBC_2.14 not found 时表示需要对glibc进行升级了. glibc版本 查看系统glibc库版本可使用如下命令: $ strings /lib64/libc.so.6 |grep GLIBC_ Centos6.5输出如下glibc版本列表, 从此图可以看出系统最高支持glibc的2.12版本: 另外, 执行 $ ll /lib64/libc** 可以看到此时的libc.so.6是libc-2.12.so的别名, 如下图所示: glibc安装 首先, 点击此处下载glibc 点击下载 , 得到 glibc-2.14.tar.gz 使用如下命令解压 glibc-2.14.tar.gz : $ tar -xzvf glibc-2.14.tar.gz 当前目录下得到目录 glibc-2.14 , 执行 $cd glibc-2.14 命令进入目录,

最近反复搭建android2.3编译环境,采用CyanogenMod for Samsung Captivate。在我 Manual Initial Build一阶段时,出错:prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-gcc: /lib/libc.so.6: version `GLIBC_2.11' not found   google了很久,大海中找到了答案: cd prebuilt/linux-x86/toolchain/mv arm-eabi-4.4.3 arm-eabi-4.4.3.flcln -s arm-eabi-4.4.0 arm-eabi-4.4.3 注:这个目录是在项目的根目录。   详细请参考:http://crancho.com/wiki/CyanogenMod_for_Samsung_Captivate#Errors_.2F_Solutions   但是,等我编译时候,出错,有人告诉我 prebuilt/linux-x86/toolchain/ 里面的东西是不能随便乱改的,那段错误是没有glibc的原因,好吧,我天真了。那什么是glibc呢?百科之:glibc是gnu发布的libc库,也即c运行库。glibc是linux 系统中最底层的api(应用程序开发接口)

自定义镜像上传阿里云

流过昼夜 提交于 2020-01-28 08:05:25
目标 1、alpine制作jdk镜像 2、Alpine制作jre镜像(瘦身) 3、Docker镜像上传至阿里云 alpine制作jdk镜像 alpine Linux简介 1.Alpine Linux是一个轻型Linux发行版,它不同于通常的Linux发行版,Alpine采用了musl libc 和 BusyBox以减少系统的体积和运行时的资源消耗。 2.Alpine Linux提供了自己的包管理工具:apk(注意:ubuntu中是apt-get),我们可以通过https://pkgs.alpinelinux.org/packages 查询包信息 3.Alpine Docker镜像继承了Alpine Linux发行版的这些优势,相比于其他Linux Docker镜像,它的体积非常小 对比常用的、没有压缩过的基础镜像(查看当前的:latest标签): Alpine - 4.8MB centos - 124.8 MB Debian - 125.1MB Centos - 196MB 4.建议使用Alpine Linux 3.10.0版本,这也是 v3.10 稳定系列的首个版本 alpine:3.10 基于alpine制作JDK8镜像 #1.下载镜像 docker pull alpine:latest #2.创建并编辑dockerfile touch Dockerfile vi

How to upgrade glibc from version 2.13 to 2.15 on Debian?

自作多情 提交于 2020-01-26 21:52:50
问题 I heard I can do it using apt-get install libc6 , but I need to add something to /etc/apt/sources.list to receive the newest glibc version. What should I do? 回答1: I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer: IMPORTANT You need to exit out of your display manager by pressing CTRL - ALT - F1 . Then you can stop x ( slim ) with sudo /etc/init.d/slim stop (replace slim with mdm or lightdm or whatever) Add the following line to the file /etc

Can I fix a “version GLIBC_2.14 not found” error without being sysadmin?

问题 I am trying to run a setup.py file on a remote machine in a Conda environment. I get the following error message: from torch.utils.cpp_extension import BuildExtension, CUDAExtension File "/home/pbrook/miniconda3/envs/super_resolution/lib/python3.6/site-packages/torch/__init__.py", line 81, in <module> from torch._C import * ImportError: /lib64/libc.so.6: version `GLIBC_2.14' not found I found one post that suggests that I don't have a high enough version of libc6 . My question: is it possible

Compile C program in Linux with different glibc library

折月煮酒 提交于 2020-01-24 11:26:44
问题 I have a firewall appliance base on linux that have glibc-2.3.4, and have not gcc to compile a program for that. when I compile a program by another linux machine, error message says: require glibc.x.x.x How can I compile a c program in another linux machine for that version of glibc? 回答1: Generally you have to use the proper building environment which contains all target libraries with the needed or compatible versions. The difference between libc variants is not only in linked library name

glibc : Test if lib as DF_1_NODELETE flag or if lib has unique symbol

别来无恙 提交于 2020-01-24 09:58:09
问题 I'm using dlopen / dlclose to load lib with glibc 2.21. Is there a C++ call to check a lib as a DF_1_NODELETE flag set ? readelf seems to be able to do it. or at least if a lib has unique symbol defined in it ? nm is definitely able to do it. ideally i would like something like : CloseLib( libHandle lib) { if( checkIfLibIsClosable(lib) ) { dlclose(lib) } } This is in order to avoid calling dlclose on lib with DF_1_NODELETE flag, as calling it will fails with an assert error : Inconsistency

Linux内存管理概述

Linux内存管理概述 2020年悄悄的来了,新年初始正是立flag的好时候,今年的flag是总结完linux内存管理和进程管理两大模块,想法是好的,希望能坚持下去,废话到此为止,今天先来介绍linux内存管理的概述,后续内存相关文章都围绕今天的内容展开。 内存管理架构图 先上图: 用户空间 应用程序并没有直接调用系统调用申请内存,是调用glibc的库函数malloc和free申请和释放内存,malloc和free是glibc的ptmalloc分配器提供的接口,ptmalloc使用系统调用brk和mmap向内核以页为单位申请内存,然后划分成小的内存块分配给用用程序。 除了glibc的ptmalloc,还有google公司的tcmalloc和FreeBSD的jemalloc。 Note: GUN C指的是glibc,ANSI C指的是libc,是标准C库,glibc对libc做了扩展,一般只用于linux 内核空间 虚拟内存管理负责为进程分配虚拟页,内存采用延迟分配虚拟页的策略,进程第一次申请内存页时,会发生页错误异常,异常处理程序从页分配器中分配物理页,并把虚拟页和物理页的映射条目更新到页表中。 页分配器负责分配物理页,内核有多种页分配器,不连续内存页分配器、连续页分配器、引导内存分配器等。 连续内存页分配器(CMA):DMA可以不需要cpu直接控制内存,但是一般需要连续的内存
