Issues between OpenJDK 11 and libstdc++

[saotoquio]

Hello. I have been using OpenJDK 11 with no problems to run my Tomcat servers, however, an user of this system made some changes recently and I am now completely unable to start Tomcat and I am not able to run Java packages either. When I try to check my Java version, this is what happens:

$ java --version
Error: dl failure on line 606
Error: failed /usr/lib/jvm/java-11-openjdk-11.0.19.0.7-1.el7_9.x86_64/lib/server/libjvm.so, because /lib64/libstdc++.so.6: undefined symbol: __cxa_thread_atexit_impl

I am completely lost on what to do. At first I thought it was something related to Java, so I tried reinstalling, but nothing changed. I realize that it is related to the libstdc++ libraries instead. I have very little experience with c++ libraries and after searching about this error for days I did not reach any conclusions.
Can someone please shed me some light on what could be the issue?

Thank you!

Is your system fully up to date? If you run yum update are you offered any updates?

[saotoquio]

Thank you for your reply, I did run the update command and there were several updates offered which I did, but the error still persists. I found the cause of it, I checked the history of one of our users and found out he did some changes to the system and I need some help figuring out if there is a way of undoing it. Here is the history:

Code: Select all

sudo yum -y install gcc
sudo yum -y install gcc-c++
sudo yum -y install gcc-gfortran
strings /usr/lib64/libstdc++.so.6 | grep GLIBC
gcc --version
cd /usr/local/gcc/lib64
sudo find /-name "libstdc++.so*"
sudo find / -name "libstdc++.so*"
sudo ln -sf /usr/lib64/libstdc++.so.6.0.19
ifort -v
sudo ln -sf /usr/lib64/libstdc++.so.6.0.19 /usr/lib64/libstdc++.so.6
strings /usr/lib64/libstdc++.so.6 | grep GLIBC
sudo yum -y install centos-release-scl
sudo yum -y install devtoolset-7-gcc devtoolset-7-gcc-c++ devtoolset-7-binutils
scl enable devtoolset-7 bash
sudo source ~/.bashrc
sudo echo "source /opt/rh/devtoolset-7/enable">>/etc/profile
ifort -v
strings /lib64/libstdc++.so.6 | grep GLIBC
strings /lib64/libstdc++.so.6.0.19 | grep GLIBC
find / -name "libstdc++.so*"
sudo cp /home/user/matlab/sys/os/glnxa64/libstdc++.so.6.0.28 /lib64
cd /lib64
sudo rm -f libstdc++.so.6
sudo ln -s libstdc++.so.6.0.28 libstdc++.so.6
strings /lib64/libstdc++.so.6 | grep GLIBC

It seems that he replaced my libstdc++.so.6 with libstdc++.so.0.28 and deleted the original one. Is there a way of fixing it? I am not familiar with c++ packages but it is affecting my Java libraries. Any help would be appreciated. Thank you!

Code: Select all

[root@centos7 ~]# rpm -qf /lib64/libstdc++.so.6
libstdc++-4.8.5-44.el7.x86_64

That shows that the real /lib64/libstdc++.so.6 should be provided by the libstdc++-4.8.5-44.el7.x86_64. To fix that you could just yum reinstall
libstdc++ and that would overwrite the change made to that file and restore the correct one.

I suspect you should also remove this user's ability to run sudo!

[saotoquio]

Thank you very much for your reply! I have tried reinstalling libstdc++ but it seems that the issue is still persisting, I tried it twice and also restarted the machine but when I run:

Code: Select all

$ javac --version
Error: dl failure on line 606
Error: failed /usr/lib/jvm/java-11-openjdk-11.0.19.0.7-1.el7_9.x86_64/lib/server/libjvm.so, because /lib64/libstdc++.so.6: undefined symbol: __cxa_thread_atexit_impl

It looks like the file is still corrupted, do you have any suggestions on what can be done? Is it possible to manually replace the libstdc++.so.6 file in a safe way?

Thank you!

What does the following command return:

Code: Select all

 
rpm -V libstdc++
 

It may return nothing.

You might want to clean up /etc/profile, removing the changes the user made.

[saotoquio]

The command returns this:

Code: Select all

$ rpm -V libstdc++
....L....    /usr/lib64/libstdc++.so.6

Does it mean that when one of the Java libraries I use call for libstdc++, it is pointed towards /usr/lib64/libstdc++.so.6 instead of /lib64/libstdc++.so.6 ? I am trying to understand what the user has done, I never cleaned up changes before but looking at this previous commands he did try to source things to ~/.bashrc multiple times.

[TrevorH]

$ rpm -V libstdc++
....L.... /usr/lib64/libstdc++.so.6

The symlink is still wrong. And you should run rpm -V as root so that it has access to everything that it needs to read to verify that it is correct.
