version GLIBC_PRIVATE not defined in file ld-linux

问题:

if anyone could give a beginner some help on gcc version issue?

I met the issue on "version GLIBCXX_3.4.20' not found". After I followed the link: How to Install gcc 5.3 with yum on CentOS 7.2? I met extra issues as below:

scl enable devtoolset-7 bash
git: relocation error: libc.so.6: symbol _dl_starting_up, version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2 with link time reference

Your problem has nothing to do with any GCC versions.

git: relocation error: libc.so.6: symbol _dl_starting_up, ...

This error most likely means that you are trying to use something other than the system libc.so.6 (perhaps by pointing LD_LIBRARY_PATH to directory that contains a copy of libc.so.6 from a different system).

Don't do that: it doesn't work. Using alternate GLIBC version is possible, but complicated. This answer provides some ways to do that.

Solution is as follows:

1. Create a local installation path mirroring / (root path) and containing usr/lib64 and a symlink to usr/lib64 at the same level as usr
2. Compile and install GLibC locally (i.e. configure --prefix=/local/installation/path (/local/installation/path contains usr and lib64 symlink)
3. Install other necessary dependencies

4. Invoke your application by as follows

   /local/installation/path/usr/lib/ld-linux-${arch}.so.${version} \
     --library-path /local/installation/path/usr/lib:/local/installation/path/usr/lib64:... \
     Your-Bin-Name \
     Your-Bin-CLI-Options
   

   NOTE: Add additional paths as needed, separating each with a colon
