OpenSUSE :: Oprofile And Debug Symbols For Glibc ?
Mar 2, 2010
How do I get debug symbols for glibc? I'm using oprofile when profiling applications. Unfortunately, the default glibc version that comes with SUSE 11.1 has the debug symbols stripped-out. That means that all libc functions get aggregated into one big blob under "glibc.so" and you can't tell whether you spend most of the time in memory allocation, syslog or lock related routines.
So, I've tried a myriad of different ways of getting the symbols. From trying to build glibc myself to hunting for dozens of different rpms on this site and on the Internet. So far - no positive results.
I followed the instructions at OpenSUSE: Bugreport KDE - openSUSE to install debug symbols for okular which seems to crash quite often for me. However gdb and the kde crash application are unable to find them. The kde app says its not a good crash report and I should follow the guide.. which has already been done.
I installed kdegraphics4-debuginfo kdebase4-runtime-debuginfo kdebase4-workspace-debuginfo kdelibs4-debuginfo libqt4-debuginfo
Is there a step I'm missing to get gdb to load the symbols or something?
1. I installed oprofile 0.9.4 on Centos Linux 5.5 this past Saturday. Since then I have been trying to learn how to use oprofile 0.9.4 on Centos Linux 5.5. If I follow the following steps running as root,
[Code]....
I obtain the following warning: warning: the last modified time of the binary file does not match that of the sample file for /home/frankc/DQTTest5/MatchUpLib/lirh5g_deb/libmdMatchup.so Either this is the wrong binary or the binary has been modified since the sample file was created. warning: the last modified time of the binary file does not match that of the sample file for /home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/MatchUpAccurate.exe
I am wondering how to prevent this warning message from occuring because it indicates our profiling results may be incorrect.
2. My second question is : when I use opcontrol --start --session-dir=/home/frankc/DQTTest/Mary5Test and profile my application using /home/frankc/DQTTest5/MatchUpTest/lirh5g_deb/Mary48.exe --run, I encounter an error when I do opcontrol --dump. The error is: Unable to complete dump of oprofile data: is the oprofile daemon running? Why is the oprofile daemon stopping when I use opcontrol --start --session-dir=/home/frankc/DQTTest/Mary5Test rather than when I use oprofile --start. I checked the permissions on /home/frankc/DQTTest/Mary5Test and it is drwxrwxrwx.
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.
By issuing the 'nm' command on shared library (internally using one static library), the functions exposed by static library is also being listed, Which allows to use internal functions which is of course not intended. I have one static library having A(), B() and C() functions. Creating one shared library which has function XYS() that is using A() and B() functions from Static library. While doing 'nm' on shared library, all the static library function are being listed.
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...
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.
oprofile-0.9.6-i486-2.txz links to libbfd-2.20.51.0.8.20100412.so ; binutils-2.20.51.0.11-i486-1.txz has libbfd-2.20.51.0.11.20100810.so. These are all the current packages as of this minute. Linking the new libbfd to the older seems to work.
About every other release of wine in the Emulators build service lately seems to require an updated version of glibc that isn't available in any of my repositories, preventing me from upgrading currently I get:
Code: nothing provides libc.so.6(GLIBC_2.11) needed by wine-1.1.42-31.3.i586 but earlier releases have had similar dependency issues, and this one doesn't seem like a safe one to ignore.
Has anyone else had this problem or is it just me? I've been grabbing GLIBC from the opensuse 11.2 Updates repo.

I have been using dropbox for quite some time but in the last few days I have been bumping into a problem.Recently I had a fresh install (GNOME3 and afterwards added KDE 4.6) and after installing dropbox I get the following error:
Code: *** glibc detected *** /home/filipe/.dropbox-dist/dropbox: double free or corruption (!prev): 0xb3d44d08 *** and dropbox terminates...
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 have installed opensuse 11.1 in my pc and I also install the xmgrace package. However, in the xmgrace some the Symbol list in the font tool menu some symbols does not work! for example the symbols: Eur,infinity, sum, partial derivative, not equal, plus or minus, etc...
today I've got an application which is need glibc-2.1 32bit but my opensuse 11.2 is 64bit.I've checked the yast but nothing interesting catch my eyes. is there any solution to install glibc 2.1 32bit on a 64bit box?
Used to work perfectly. I attempted to install VPN client, result is can't connect to anything. Networks are seen by network manager, nothing happens when click connect. Results below:

Advice is to use output of dmesg command to find problem, but as above I don't get any results for this in terminal.

I would like to build a sticky subject about repairing openSUSE boot.This article,once complete (not by me alone) should be made sticky (to have it in front of the forum)- these problems are frequent and disturbing.I know the great work done by please-try-again. But very often we don't need any script (and running a script from rescue mode is difficult) - that said I vote to have the pta scripts included in the rescue system !So I would like to focus on command line fixes.
When I debug a program with GDB and hit a break point I get:
Missing separate debuginfo for /lib64/ld-linux-x86-64.so.2 Try: zypper install -C "debuginfo(build-id)=2b25d8329d1aa713a2cc61b5cb701f6f89c78022" Missing separate debuginfo for /lib64/libm.so.6 Try: zypper install -C "debuginfo(build-id)=f05646449077dfbf15d5f78251a3b25e0f955dd9" Missing separate debuginfo for /lib64/libc.so.6 Try: zypper install -C "debuginfo(build-id)=9b674b2caef1982db55e436bca814060e1705b7f"
When I install the suggested packages the debuginfo does not match the object files. I get:
warning: the debug information found in "/usr/lib/debug//lib64/libc-2.11.2.so.debug" does not match "/lib64/libc.so.6" (CRC mismatch). warning: the debug information found in "/usr/lib/debug/lib64/libc-2.11.2.so.debug" does not match "/lib64/libc.so.6" (CRC mismatch).

The last package is not found. Is this missing from the repositories?
I am a hobbyist interested in development and have recently decided to migrate from Windows to Linux and after trying out a number of distributions decided to use openSUSE. After getting somewhat more comfortable with Linux and openSUSE I decided to try and get comfortable with development on this platform.
And hence my problem: After compiling the simplest of programs (hello world) and trying to step through it with gdb I get this output: Missing separate debuginfo for /lib64/ld-linux-x86-64.so.2 Try: zypper install -C "debuginfo(buildid)=2b25d8329d1aa713a2cc61b5cb701f6f89c78022" Missing separate debuginfo for /lib64/libc.so.6 Try: zypper install -C "debuginfo(buildid)=9b674b2caef1982db55e436bca814060e1705b7f"
As soon as I type the command start in gdb. Naturally I tried the recommended zypper downloads to no avail. Furthermore I sought out the glibc debuginfo in the software manager and found nothing which I have not already installed.
On my system are:-devel-32bit glibc glibc-32bit glibc-devel glibc glibc-info glibc-locale glibc-locale-32bit glibc-profile glibc-profile-32bit gdb gdbm gdbm-32bit
All of these are the latest version from the standard 11.3 repositories. I believe these are all the requirements I should need to not have gdb give me errors but sadly that is not the case. Lastly I am running on a 64bit version of openSUSE 11.3.
Recently, I upgraded 11.1 to 11.2. Everything seemed to go fine. However, for some reason the system boots with the debug kernel - 2.6.31.5-0.1-debug. According to Yast every kernel under the sun seems to be loaded on the system. Grub, however, gives two choices - one for the regular and one for the failsafe system. They both boot to the debug kernel.
How do I get this thing to load into the regular, as opposed to the debug, kernel?
Now I've got debug, default, desktop, ec2, trace, vanilla, xen installed im my system. I usually only boot with desktop, and I was wondering if it is OK to remove other stuff except debug, default, and desktop.
