glibc

问题 (a) I was trying to run a Software (64-bit) on a 64 bit Cent OS-6 based System (with no internet access), and I got following error: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory (b) On searching it was understood that 32-bit glibc is to be installed. Searched all dependencies in a different system with internet connection, downloaded from internet, and loaded all rpms in the system via pendrive and tried to install glibc for 32 bit. I got below error message is obtained

问题 i am currently experiencing a problem were i get *** glibc detected *** ./efit: free(): invalid next size (fast): 0x00000000006127f0 *** with the usual memory map and backtrace information that comes with a glibc error. i am, however, unable to find the cause of this problem. it seems like (basically) my entire program is finished by the time this happens. one thing i read online is that this could be due to lack of deallocation. now, i have been running the program without deallocating a few

问题 Problem is, that there seems to be no updates for glibc if I run apt-get upgrade How can I check if my system has this vulnerability, and how can I fix it? 回答1: Add the following lines to /etc/apt/sources.list (see https://wiki.debian.org/LTS/Using): deb http://http.debian.net/debian/ squeeze-lts main contrib non-free deb-src http://http.debian.net/debian/ squeeze-lts main contrib non-free Run > apt-get update Check that package list has been updated: > apt-cache show libc6 | grep Version

问题 I am trying to install glibc on Alpine Linux. I am running Alpine Linux in the Docker. Here are the steps I am using: docker pull alpine docker run -it alpine /bin/sh apk add --no-cache make gcc linux-headers bsd-compat-headers gawk bison binutils coreutils diffutils gettext bash grep sed texinfo perl wget https://ftp.gnu.org/gnu/glibc/glibc-2.28.tar.gz tar -xzf glibc-2.28.tar.gz cd glibc-2.28 mkdir glibc-build cd glibc-build ../configure --prefix=/usr \ --disable-profile --enable-add-ons \ -

问题 What is the safe/portable way to convert a number to a string (and the other way around) ? I'm on Linux and my settings locale is so that when I use sprintf numbers have a "," instead of a "." as a separator. Sometimes I want them that way, Sometimes not :) I saw some solutions that imply playing with users settings. Clearly that's something one should not do. Somebody suggested using uselocale snprintf : simple way to force . as radix? can someone elaborate a bit (looks like it's buggy on

问题 According to posts from 2008 (I can't find it right now), glibc heap check doesn't work in multithreaded environment. Is it still situation now in 2010? Does heap check enabled by default? (gcc 4.1.2)? I don't set MALLOC_CHECK_, don't aware of calling mcheck(), but still sometimes receive double free glibc error with backtrace. Maybe it's enabled by some compilation flag? 回答1: By default, without using malloc_check_ or mcheck(), glibc does some little checks that doesn't hurt the performance,

问题 I am building GCC for a foreign architecture on Ububtu trusty. I am on an i686 and building for i386. I am having the same problem as GCC build problem (#include_next limits.h). From the discussion in the link I posted this comment struck me as being the best explanation however I am not sure what the poster means by (the toolsets copy)....I suspect he means I need some other tarballs apart from the gcc tarball. I believe I have libc6-dev-x32 and libc6-x32:i386 but these could be something

问题 I am a newbie to C++ compilation in production environment I wonder if there are any issues in running a C++11 executable compiled with gcc4.7 ( on debian 6 ) on a computer with an older gcc version, an older glibc / libstdc++. Thanks EDIT : I want to add more details to my question ( maybe it's better to open a new question ? ) I need to compile a legacy C++ code with new libs in C++11 on debian 7 ( for gcc 4.7 ) and run the exe on debian 6 on fedora 18 ( for gcc 4.7 ) and run the exe on

问题 Can I use fprintf(stderr) in a signal (SIGALRM) handler with glibc/linux? 回答1: No you cannot. Check the manpage signal(7) for a list of async-signal-safe functions. fprintf is not included in that list. If you don't need formatting then you can use write(STDERR_FILENO, <buf>, <buflen>) to write to stderr. 回答2: This is not safe, quoting IBM DeveloperWorks article about Signal Handling Safety Suppose the signal handler prints a message with fprintf and the program was in the middle of an
