My users need to run an application which was build with newer GLIBC_2.11, while my system only gets GLIBC_2.4. It shows error "cannot find libc.so.6 GLIBC_2.11" whenever I run it. I cannot upgrade the system, so I have tried building Glibc 2.11 (for example:/opt/glibc-2.11) to another directory, but when I point LD_LIBRARY_PATH to /opt/glibc-2.11, I cannot run any commands because of error invalid LFS ABI. I also tried using LD_PRELOAD, but it does not work. Please help me, how can I fix this problem.
I've been working to get gcc up and running on a new install of Fedora 13. glibc-devel had dependencies upon installation where it required glibc and glibc-common, both 2.12.1-3. No problem, found both at rpm dot pbone dot net. However, when I try to install the following circular dependency results... it doesn't matter the order of install.
Code:
[root AT localhost gcc_install]# rpm -ivh glibc-common-2.12.1-3.x86_64 .rpm error: Failed dependencies: glibc = 2.12.1-3 is needed by glibc-common-2.12.1-3.x86_64
I notice that these two packages contain the same files and uninstalling glibc-i18n doesn't uninstall the internationalization files, because they are also in the glibc package. Is this a mistake or is this normal or is there a reason for it ? I just made my own glibc package to fix this, but was wondering why this is the way it is...
I have installed Zimbra 6.0.1 and updated to Zimbra 7.1.0, the problem is that it needs the glibc-2.10 to start one of its services. I tried everything but i'dont get to update the glibc.
OS : Oracle Enter Prise Linux 6 (equivalent to RedHat)
I am in process to install oracle 10g on said OS.My process fails and after digging up , I came to know that some of the oracle libraries are compiled on 32-bit architecture and it require glibc-32 bit . also it require for gcc-32 bit.
Now i have downloaded all the required rpm for gcc-32bit . when I try to install glibc and its dependencies , it gives me error that newer version already exist.
How can I install , Gcc-32bit(libgc, libstd-i386 etc) in parallel or standalone?
I made an update of my Centos 5.5 yesterday. In doing so glibc has been updated to glibc.i686. Just now some of my FPGA tools crash. Unfortunately there isn't a downgrade for glibc.i686. How can I replace glibc.i686 by glibc.i386?A simple yum install glibc.i386 conflicts with the files from package glibc-2.5-65.i686

I am in very much need to resolve the issue of Upgrade redhat5 from glibc 2.5 to glibc 2.7. The problem is when I run a binary compiled on our build setup (glibc 2.11) on Suse 11 (glibc 2.9) it works fine...
But the same binary do not work on redhat enterprise version 5 telling error as need glibc2.7 or sometimes segmentation fault for the same binary execution.
I tried upgrading the redhat glibc 2.5 to glibc 2.7, but not successful.
We recently ported an application over from IRIX to Linux, specifically SUSE Enterprise 11 and gcc (glibc 2.9). On IRIX there was a library trace utility call 'par' that allowed me to execute a C program and trace all the library calls it made, tracking how much time was spent in each call. I have been trying to find something similar for SUSE. I have found the ?trace programs (strace, ltrace, and ktrace) none of which is default installed on SUSE 11.Does any one have a suggestion on which ?trace to install and use or is there something else out there better?
I'd like to write a C/C++ program, that would grab content of window (in form of pixmap), which belongs to another application and do something with it. However, I ran into problems already at the beginning. In all toolkits I have searched through, I only found one function that claims to do what I want, namely XGetImage from Xlib. However, among other parameters like Display, coordinates, etc., it requires a Drawable. How do I specify a Drawable, that would correspond to the window I want to grab content of? Is there any easier way to achieve this?
Yesterday, I think I did something stupid: I removed kernel-headers, gcc, glibc-devel and glibc-headers. My box is a CentOS 5.4 webserver (it has loads of packages installed, but that was done through Virtualmin config, so it's quite coherent all in all). The thing is that now I need to reinstall at least the headers and glibc, but hey! this is what I get :
I am new to C and linux. My code below does arbitary writes but I cant figure out where or how it does it.
I am calling the insertNode() function with seq = 'MISSISSPPI$' and alphabets = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ$'
Code:
Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
I have a perl script which was written for me by a professional (I have some basic knowledge), is working fine at the moment but on moving it to a different server as I'm changing a server (new server is shared and supports perl modules), I get the following message"Global symbol "$psid" requires explicit package name at admin.pl line 16". I get this for every single one for my values for the whole script which is about 2000 lines. Same error messages for main and admin.I haven't changed anything on moving it to the new server apart from the first line which is the location of the perl.I thought it would be too much to post the whole script here but anyone has any idea why is doing it taking into account that it works on a different server?
I'm building a certain RPM package that must require an old version of that same package in order to be installed/upgraded. Is this possible?
For example:
For a package foo v5, somewhere in the spec file: "Requires: foo >= 4"
I'm declaring this on the Requires tag of the spec file, but when I try to install or upgrade the package (without having the previous required version installed) I get no dependency error! As for other dependencies it all works fine. If, instead, I create a package named "bar" that "Requires: foo >= 4", when installing I do get the expected dependency error. I'm thinking it's not possible to require an old version of the same package.
The resulting debian package then has an empty "depends" field and no binary.
I used the Qt Hello World example application to start.
I changed debian/rules (generated by dh_make) so that it runs qmake as follows:
Code: Select all#!/usr/bin/make -f # -*- makefile -*- # Sample debian/rules that uses debhelper. # This file was originally written by Joey Hess and Craig Small. # As a special exception, when this file is copied by dh-make into a # dh-make output file, you may use that output file without restriction. # This special exception was added by Craig Small in version 0.37 of dh-make. # Uncomment this to turn on verbose mode. #export DH_VERBOSE=1
am using a PC104 with Linux and i need to control it with a controller that is connected via RS-232 or USB port. I need to launch one or more application some specific message come through RS-232 port. Is that doable? If yes how? I am beginner with C++ on Linux so i don't really know specif libraries. If possible i would like to use pure C and not C++.
I want to write an application with an interface similar to those used in non-GUI linux installation programs. It is not really a pseudo-graphic. Does anybody knows an appropriate library?
i need to debug a application which is using many threads. i am using eclipse with GDB debugger but it is not possible to debug it since it has a lot of different threads and i can not not debug it as wre debug in case of single thread(main) . So i would like to know, is there a way to debug such an application, if there is some tutorial that would be nice to know.
I'm trying to learn how to cross-compile libraries (static and shared) and executables for the Blackfin + uClinux environment.At this point, I can successfully compile a stand-alone "Hello, world" but fail when trying to add a (static) library to the mix.Here's the source code I wrote:
I'm developping a C# app in Windows using VS2010. It has one form and communicates as a client with a server.A receive thread displays incoming data while buttons and a timer send data. All workingThe form has a button that calls the below method to disconnect from the server.
Is there a somewhat straightforward way to get the name or pid of the application that is under the mouse's cursor? What I'm trying to do: This is just a "what if" at this point, I would like to run some script that would obtain the name/pid of any application that the mouse cursor is on, and use xte to assign different functions to different mouse buttons. For instance, assign a given button the Forward or Back function when the cursor is on a browser, but assign a scroll-left or scroll-right to the same button when it's on a spreadsheet. Is there any way to accomplish this, say, in a script that I could run at startup as a background process?
I never had to use anything more than -l , -lm , -c ,-o.It was only through dev documentation that I came across glib. Now I want to to compile and link a program with glib.
I want read the log messages to my 'c' application , i am using the fedora core 8 operating system , how to read the system log messages(syslog) through my application.
I have developed a proprietary multithreaded application using Qt library version 4.2.1 on RHEL 4 platform. The application communicates with different external interfaces using serial communication using well defined protocols. For each system I have a thread that handles data acquisition and processing, it sets an update flag which is read by the GUI thread to update GUI after specified number of seconds. The incoming data from external systems is processed and updated on GUI at certain intervals. Each system update rate on GUI is different. Generally it is 1 second. Their rate of sending data is different and is generally 1Hz, 5 Hz and 10 Hz. For systems with string data I have no issues. But some systems send raw data and I have to process every byte of the entire packet, for which I have to use for loops. Now my problem is if I keep the update rate of GUI for such systems less than a fixed number of seconds (which I have to calculate by hit and trial) the application hangs after sometime. I have tested this system exlusively by switching of all other systems and it hangs standalone.
This leads me to conclude that timing of GUI update is what is causing the application to hang. Also I read somewhere on the net that in multithreading application timers play an important role and slight variation in timing can lead to hung applications. As of now I have kept 5 seconds as the GUI update time and app runs fine. Can somebody suggest something else which might be the cause?Note that I have used mutexes, wait conditions and all necessary tools which are used in multithreading app. But it is only the timer on which I could pin down the issue.
1. How to use the the font in the application? Any code example? 2. How to install the font for linux? 3. How to make the installed font as the system default font? 4. How font/text is rendered in linux? Any inforamation about the font system in linux?
