[SOLVED] error while loading shared libraries: libquadmath.so.0

Sonia Bargn · 11-28-2014, 05:04 AM

Dear all;
I run an execute file named "A" gets it's input from a text file "B.inp"
but I face this error:
A < B.inp
: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory

I've downloaded libquadmath and when I want to install it ,the other error said I don't have libgc package!!! but I have libgc!! is it because of existing two different repository that it can't share their information?
my operating system is Centos6;
what shall I do?
Thanks for your attention

would be nice to give detailed descriptions, and also please post the error messages you've got. Probably there is a version mismatch problem, but I can only guess....

@Sonia Bargn.

libquadmath.so.0 is provided by gcc version -4.6 -4.7 -4.8 .

Later versions of gcc for CentOS 6 are provided by "devtoolset" from CERN
http://linux.web.cern.ch/linux/devtoolset/
→ →
# wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoo...evtoolset.repo
# yum install devtoolset-1.1
Or :
# yum install devtoolset-2

Dear knudfl;
Thanks for your comment;
I did what you said but I face this error:

warning: rpmts_HdrFromFdno: Header V4 DSA/SHA1 Signature, key ID 1d1e034b: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern

what do you think about it?

← #4 .

Usually no problems by installing the devtoolset´s on CentOS.

Which command is it that leads to the error ...
".. Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern"
(An error output like you show above really tells very little
without the connected command.)

Please try again. » # « means of course the root prompt :
1) $ su <enter your root password>
2) # wget -O /etc/yum.repos.d/slc6-devtoolset.repo <url>
3) # yum install devtoolset-2

Dear knudfl
Thanks again;
I tray again for both devtoolset-2 and devtoolset-1.1 , but again there is this error:

warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID 1d1e034b: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern
GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern

I think I face a basic problem, what is your idea? it's so important to me to solve this problem

Well, then you can do :
# yum install devtoolset-1.1 --nogpgcheck

Or, you can simply edit one line in /etc/yum.repos.d/slc6-devtoolset.repo
.. from gpgcheck=1 to gpgcheck=0

Code:

[slc6-devtoolset]
name=Scientific Linux CERN 6 (SLC6) - Devtoolset addons
baseurl=http://linuxsoft.cern.ch/cern/devtoolset/slc6X/$basearch/yum/devtoolset/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-cern
gpgcheck=0
enabled=1
protect=1

Dear Knudfi

I did what you said and fortunately devtoolset-1.1 installed,I changed gpgcheck to 1 as well, but ... error that I entitled in this thread ... exist !!!
can I edit other line in /etc/yum.repos.d/slc6-devtoolset.repo
.. from enabled=0 to enabled=1 ??

Why would you do that ? And which line number is it about ?

The lines with "enable=0" are for software, that you don't need :
"enable=0" is there for a reason.
So why would you do that ? ?

Dear knudfl
I'm so sorry ,I made a mistake. now I just changed gpgcheck to 0 in all part

Sonia Bargn · 04-03-2015, 11:59 PM

Dear all
After installing gcc,f77,g77,c++,gfortran this problem was solved.there was no need to install libquadmath.
