Programming :: Best Way To Trace Library Calls In C On SUSE Using Glibc 2.9
Sep 27, 2010
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 am trying to port some "C" code from Solaris to Linux. I have a Dell PowerEdge R610 with an Intel Xeon E5504 quad core processor running Red Hat Linux Enterprise 5.3. I am compiling in 64 bit mode. I have managed to get the code compiled and linked, but when I attempt to execute it, I get a core dump in one of the C library calls (like strcpy or printf.)
I have a static library that contains our own code that makes the call to the C library. If I move the library method into the source file with the main method and rename it to be certain that I am executing my method instead of the method in our library, the call succeeds. Eventually another static library call is made that results in a core dump in the shared object. I compile my library code into a static library with gcc as:
What is the real difference between system calls and normal function calls. Ultimately function calls too would be passed to kernel for some or the other work.
I'm trying to install the latest debug flashplayer available here:

linked from this page
[URL]
I follow the embedded instructions and this is the error:
root@vostro-ubuntu:~# /home/berrie/work/download/install_flash_player_10_linux/flashplayer-installer [: 258: closing paren expected ERROR: Your glibc library is older than 2.3.
[code]....
I'm running Ubuntu Karmic Koala and it is up to date.
Could it be that the flash installer parses the version number wrong as previously it was glibc-2.9-1, a '9' after the dot, now there is a '1'.
I've been looking awhile now, but no patch for this is yet to be found. Does anyone have more info, or better, a fix? Last version from GNU's ftp server is also vuln as of this writing.
I have a use case where in I am trying to build a yacc program using bison. When I run this on SLES 9, I get errors. But the same works for me fine on a SLES 10 system.
The versions of bison, glibc are different. Hence I moved the rpms from SLES 10 machine to SLES 9 and did a rpm2cpio of these 2 to a temporary folder and did a export of LD_LIBRARY_PATH. When I try to run the program ( ./bison) I am getting a segmentation fault. I have the following questions :
1) IS the scenario what I am trying to do - using a newer version of libc( from sles 10) to sles 9 supported ?
I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.
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...
The usual answer is debian's ldd(1) and I found broken things due to past lib abuses I previously hadn't understood I'd did - or rather hadn't realized because by looking it "looked ok and worked" - but i had problems. many i fixed.
After I ran a new script: it showed some i'd STILL missed after carefully re-doing /lib by hand (and using /var/lib/dpkg/info/libs.list)
I just made something that might be nice. seems to be the only thing that does it. but its' small and quick and has (tty/stdout) output still.
the had part isn't finding info, objdump(1) does that wonderfully : it's using it..
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.
How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.
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 have a problem in making multiple calls using PJSIP. I registered different accounts that implements IAccount and added that in the CallManager. When i try to make the calls from the same CallManager, I could able to make the first call. When second call is made the first call got cut and it is alerting and the same for the thrid call..Could anyone help me in this regard.
Note: Calls has to be made from different numbers to different destinations. Is it possible to make multiple outbound calls simultaneously from the same instance of CallManager?
I know there is a way to call winapi in runtime in windows. I want to ask how can I call a system call in gcc in runtime (when I don't know what it can be)? I don't mean syscall that I think is for calling only system calls and not library functions.
Is there a way to hook calls to new/malloc, delete/free in C++? I tried the following methods: LD_PRELOAD -> fails for malloc, because dlsym seems to depend on malloc -Wl,--wrap,malloc -> doesn't work for 'new' gcc hooks -> doesn't work always, e.g. for uclibc there are no hooks Are there any other methods I could try?
I'm trying to write a C program that extends an array to any user inputed size.
Code: if (arraysize == 0) { arraysize = (int) pos + 1; a = (int *) calloc (arraysize,sizeof(int)); for (i = 0 ; i < arraysize ; i++ ) a[i] = -1; code....
The program dumps with that sequence of inputs everytime, but might dump an input before or after if different positions are requested. Interestingly, when I tested pos = 2000..2008, I got no dumps. So is realloc somehow trying to extend the array into bad space?
I'm trying to produce a alphabetic, non-repetitive list of all System service calls in all c files located in a folder. Here's what I got so far. grep -ow '[A-Za-z]*SYS[$][A-Za-z]*' *.c | sort Which produces all system service calls in alphabetic order I just need to find out how to make it non-repetitive.
How does a C program start in linux? Is main() the first function called in the a c application by kernel. I understand it is the first called function written by the application programmer, but the question is to understand the what all kernel does and what all functions it calls before calling main()
I am working with fedora 6 , i386 architecture.I am trying to write on keyboard port via program.On inspation i come to know that 0x0060 to 0xz006f are used for keyboard in linux 2.6 kernel in the i/o space from kernel.
