Programming :: How Libc Is Linked In Crosscompiler Chain
Sep 10, 2010
1. I need to use clock_gettime(), in <time.h> it is: extern int clock_gettime (clockid_t __clock_id, struct timespec *__tp) __THROW; and in a successful build .so it is unsolved. In final app to lonk to this .so it is also unsolved. which lib missed in .so or app build?
2. libc include several libs, which are liked by default? say stdc++, rt? rt1/rt2 what does they do?
I've got a shared (Windows/multiuser Linux) laptop, and I've got installed World of Warcraft and some steam games in Windows. With steam games, there is (almost) no problems. I've installed steam in Linux, and soft linked the 'steamapps' directory (per-game compatibility is another issue). With WoW, the problem is different. I would like to have almost (but not) all files. Under World of Warcraft, every file and directory must be linked except the Interface directory and WTF/config.wtf file (so every user can play with their own settings and addons). How can I have a mix of linked and not linked files without linking every file? If I link manually every file/dir, when updating from Linux other users and Windows Wow is not updated; when updating from Windows, new files remains "unlinked".

1 why cann't i debug the test? because i can't step into the "operator new" function.
[URL]...Now it works in Windows platform. Some functions rely on win-specific code and need to cross-platform alternatives. Can some one help to build chain(make or cmake) for this awesome project? any one can compile the Linux generator and transfer the project under *nix platform.
Okay, just wanted to be perfectly clear on this point... /static/ software builds don't link to /any/ shared libs, right? I.e., can a static-built C program run on a system without a libc installed?
I am trying to build a cross GCC compiler for PPC476. I applied all the relevant patches. Cross compiler build was successful. When I try to compile the source code using the cross compiler I am getting the below error message. I think this is something related to linker.

I would like to complete inode information from the struct list_head structure of super block structure of vfs.System call are doing operation internally, but no system call to traverse?
I have a linked list that two threads work on simultainiousley.The first thread is adding elements to end the linked list while the second is removing them from the front. Can this be done without a lock on the linked list head when elements are beingadded/removed?
I think this lock is causing a performance hit to my application. If there isnt any safe way without it then thats fine but just thought I would check.The first thread uses this fuction to add elements to the list. Full source here. [URL]
Code:
/* Lets add the new packet to the queue. */ pthread_mutex_lock(&workers[queuenum].queue.lock); // Grab lock on queue. if (workers[queuenum].queue.qlen == 0){ // Check if any packets are in the queue.
I got a digital picture key chain and it comes with windows software. I plugged it in and it's detected as a read only usb storage, so I can't upload any pictures in it
I've recently installed Ubuntu 10.04 it installed and chain-loaded correctly however I installed it on partition that was too small so I used gParted to copy the files 1:1 to a freed up partition.The result was it copied fine but the Grub file became messed up.
I had to manually reinstall Grub2 from the LiveCD and the Linux was starting up fine, however now I'm unable to boot to Windows.Is there an easy way to reinstall/re-chain the Windows bootloader so its able to chain-load from Grub.
I have created a new user define chain # iptanles -N blacklistNormally when we add a new rule it automatically insert in the default iptable but when we create a user define chain then how can I add my rules in this chain ?
I couldn't find any package containing a static version of the C library for 32-bit. Did I miss something or is it really not available, and if so is there a reason why?
Im using buildroot to generate a file system . in tat one package module-init tools need static version of libc.a . so may i know how to install tat in fedora 12 ?mine CPU is as given below

I'm on Ubuntu 11.04. I get the above error when running a utility to get code from a version control system (StarTeam). The error looks generic enough that I'm hoping its an easily resolvable system problem. Below is how I get it ...
Code:
$ /bin/sh -c stcmd label -x -nologo -stop -p username:password@mydomain.com:9999/NNA/NNA/Technology/nna/tools/selenium -nl selenium-utils-1.0 -b strings: '/lib/libc.so.6': No such file
I've been working with out servers for the past several years. We have a mix of OS. Fedora, Ubuntu, RHEL, etc. I've accidentally trashed the libc.so.6 link and now nothing but shell commands work.
I tried to echo "/lib/libc-2.10.2.so into the /etc/sestatus.conf file, but that didn't have any affect. Does anyone know where the search path is maintained besides PATH so I can try to point the apps to the /lib/libc-2.10.2.so file? I have a bunch of SVN repos on this server and right now, no one has access.
What is the connection between the kernel and Libc (either gLibc, uClibc, etc.)?
For instance, what happens if I upgrade the kernel but keep an older version of Libc and applications that rely on it: Will applications keep running, and I will need to upgrade Libc only if I install newer applications that expect to find new systems calls in the kernel that they reach through Libc?
I am trying to install sysstat-5.0.5-1.x86_64 rpm, but thats needs to install dependencies libc.so.6... For details I have attached the screenshot. No yum is configured there.
I tried to install the cross toolchain for armhf but, apparently, I borked something. I tried to follow the directions here : [URL] .... but he lost me at "The key fingerprint is: 084C 6C6F 3915 9EDB 6796 9AA8 7DE0 8967 1804 772E (you will need to install curl in a bare chroot)".
I have successfully installed the toolchain according to the gnuarmeclipse method and don't recall any references to "chroot"; it was pretty straight forward. That machine took a dump and I need to start over. I would like to install the toolchain without Eclipse getting in the way (and hogging memory).
There may be a way not to download all dependency and install one by one.But how?Sorry for such a basic question but i could find only solutions for ubuntu.
