When we run opm on RHEL8, we met the following error
./opm: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./opm)
./opm: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by ./opm)
./opm: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./opm)

Note: it happened for 4.15.0-ec.3
I tried the 4.14, it works.
I also tried to compile it with latest code, it also work.

    4.15.0-ec.3

    always
