yum install libstdc++.i686

...

Transaction check error: file /usr/share/gcc-4.8.2/python/libstdcxx/v6/printers.pyc from install of libstdc++-4.8.5-16.el7_4.1.i686 conflicts with file from package libstdc++-4.8.5-16.el7_4.1.x86_64 file /usr/share/gcc-4.8.2/python/libstdcxx/v6/printers.pyo from install of libstdc++-4.8.5-16.el7_4.1.i686 conflicts with file from package libstdc++-4.8.5-16.el7_4.1.x86_64

What does this tell me and how can I fix it?

Here's the reason why I need it:

Yes, I did try to cheat and just linked the 64bit

# ln -s /usr/lib64/libstdc++.so.6 /lib/libstdc++.so.6
# ls -lad libstdc++.so.6
lrwxrwxrwx. 1 root root 25 25. Dez 09:53 libstdc++.so.6 -> /usr/lib64/libstdc++.so.6

but got this as a result:

./arcache: error while loading shared libraries: libstdc++.so.6: wrong ELF class: ELFCLASS64

I ran into this same issue. I was able to use yum to download the RPM, then force install the rpm.

$ sudo yum install --downloadonly --downloaddir=/var/tmp/ libstdc++.i686
$ sudo rpm -ivh --force --nodeps /var/tmp/libstdc++-<VERSION>.i686.rpm

yum

--downloadonly - only download the package into an RPM

--downloaddir - download an RPM to the specified dir

rpm

--ivh - install/verbose log/print hashes for progress

--force - ignore existing installs, this is what ignores the above error

--nodeps - ignore dependencies

It says you i686 package not match with you x86_64 package(must with same version number), update the x86_64 package first, then try again:

yum update -y libstdc++.x86_64
yum install libstdc++.i686

I had to expand on some of the previous answers as they will not install all of the dependencies.

yum install libstdc++.x86_64 -y
rpm -e --nodeps libstdc++.x86_64
rm -f /var/tmp/libstdc*
yum install libstdc++.i686 -y
rpm -e --nodeps libstdc++.i686
yum install --downloadonly --downloaddir=/var/tmp/ libstdc++.i686
yum install libstdc++.x86_64 -y
rpm -ivh --force --nodeps /var/tmp/libstdc++*
rm -f /var/tmp/libstdc*

simple comment but the update for the x86_64 appears to me to be clearly the right answer! Small edit for me would be to just

yum update -y libstdc++.x86_64 libstdc++.i686
