GLIBC 2.14 installation error: forced unwind support is required - RHEL 7.5

Question

I have upgraded my RHEL OS from 6.7 to 7.5. After upgrading, I found some issues when trying to run yum . Below are the details.

# yum repolist

There was a problem importing one of the Python modules                                                                                                                       
required to run yum. The error leading to this problem was:                                                                                                                   

/lib64/libc.so.6: version `GLIBC_2.14' not found (required by /lib64/libgcc_s.so.1)                                                                                        

Please install a package which provides this module, or                                                                                                                       
verify that the module is installed correctly.                                                                                                                                

It's possible that the above module doesn't match the

After getting this error, I just installed python2.7 and GLIBC 2.14. But when I am trying to install GLIBC 2.14 from my current GLIBC version 2.12, it is throwing some error. Below are the steps that I am using to install GLIBC 2.14:

1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. sudo make install
8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

In step5, I am getting error. Below are the details:

# ../configure --prefix=/opt/glibc-2.14

checking for forced unwind support... no                                                                                                                                
configure: error: forced unwind support is required

I am unaware of this error "unwind support is required".Please let me know how to setup/install forced unwind in Redhat 7.5.

Answer 1

add libc_cv_forced_unwind=yes when configure:

../configure --prefix=/opt/glibc-2.14 libc_cv_forced_unwind=yes

and make
