Problem starting Flock

[rohitsz]

Greetings there,

 

I just downloaded flock.

 

I tried to start it and i got the following error:

 

[root@localhost flock]# ./flock
./flock-bin: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
[root@localhost flock]#

 

Also i checked whether i have libstdc++ or not,

 

[root@localhost flock]# urpmi libstdc
No package named libstdc
The following packages contain libstdc:
libstdc++-devel
libstdc++6
[root@localhost flock]# urpmi libstdc++6
Package libstdc++6-4.2.2-0.RC.1mdv2008.0.i586 is already installed
[root@localhost flock]#

 

Please tell me what next to do.

 

Thanks,

rohit.

On my Mandriva 10.2 install, the file libstdc++.so.5 is within libstdc++5-3.3.4-4mdk.i586.rpm

If you're using Mandriva 2008, as root do

urpmi libstdc++5

Hi,

 

If you're using Mandriva 2008, as root do

urpmi libstdc++5

 

I did the same, i got the following output:

 

[root@localhost rkumar]# urpmi libstdc++5
No package named libstdc++5
[root@localhost rkumar]#

 

Thanks,

rohit.

Clearly, you just need to install whatever package contains libstdc++5. But I believe Greg2's suggestion of:

 

$ urpmi libstdc++5

 

...while handy, will only look for an installed package named 'libstdc++5', and not find a package containing a file with the name 'libstdc++5' particularly if the package containing it is named differently. And since it's not installed you get "No package named libstdc++5" which is not a lot of help. Now, daniewicz was kind enough to give you the package name for libstdc++5 for his machine, but not how to find the correct package for yours. You can do a search for 'libstdc++5' in MCC>Software Management, but this is one of those times when some of the old 'rpm' commands can come in handy...

 

To find a package for your installation named 'libstdc++5' *or* one that contains libstdc++5, in a console type (you do not need to be root):

 

$ rpm -q --whatprovides libstdc++5

 

For example, on my 10.1 machine I get:

 

$ rpm -q --whatprovides libstdc++5

libstdc++5-3.3.4-2mdk

 

This query will not work on *any* file in a package but IIRC the package or file doesn't have to be installed, if it's in the rpm database you should get a result. Then just install that package.

 

To find what what apps require libstdc++5:

 

$ rpm -q --whatrequires libstdc++5

 

...and you'll get a list of dependencies. There are many other possible queries, see: man rpm.

 

I hope I got this stuff right. If not feel free to pile on.

I did check out the --whatrequires and --whatprovides option of the rpm command, but to my dismay, no success :huh:

 

[root@localhost rkumar]# rpm -q --whatprovides libstdc++5
no package provides libstdc++5
[root@localhost rkumar]# rpm -q --whatrequires libstdc++5
no package requires libstdc++5
[root@localhost rkumar]#

 

Also i checked out MCC for the "listdc" package, it shows libstdc++6 as the only matching result found.

I do not have the equivalent "-devel" packages installed.

Should i install them?

 

Thanks,

rohit.

We need a Mandriva 2008 user out there to help. How is libstdc++.so.5 installed on a Mandriva 2008 system?

[Greg2]

[root@localhost rkumar]# rpm -q --whatprovides libstdc++5
no package provides libstdc++5
[root@localhost rkumar]# rpm -q --whatrequires libstdc++5
no package requires libstdc++5
[root@localhost rkumar]#

I'm using Mandriva 2008.

[greg@halfway ~]$ rpm -qa |grep libstdc
libstdc++-devel-4.2.2-0.RC.1mdv2008.0
libstdc++5-3.3.6-3mdk
libstdc++6-4.2.2-0.RC.1mdv2008.0
[greg@halfway ~]$ locate libstdc++.so.5
/usr/lib/libstdc++.so.5
/usr/lib/libstdc++.so.5.0.7

I installed it with (as root)

urpmi libstdc++5

so you must not have all the software repos set up on your system properly. Did you use the easy-urpmi link at the top of the page to set them up?

[daniewicz]

Thanks Greg2.

 

rohitsz:

It looks like you need to install libstdc++5-3.3.6-3mdk

[Steve Scrimpshire]

I would second the idea that urpmi sources are not set up correctly. The pkg is in contrib:

[root@localhost ohms]# urpmq --sources libstdc++5
ftp://ftp.proxad.net/pub/Distributions_Linux/MandrivaLinux/official/2008.0/i586/media/contrib/release/
libstdc++5-3.3.6-3mdk.i586.rpm

[rohitsz]

Hi,

 

Yes my urpmi sources were not setup at all.

I apologize for such negligence.

 

Thanks a lot for the help.

rohit.
