I am on a

box without admin rights. From various applications/install scripts I get

 /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by...

(e.g. from jupyter notebook)

My gcc version is gcc (GCC) 4.8.5 and from strings /usr/lib64/libstdc++.so.6 I get GLIBCXX_3.4.13 as the latest version.

I have already installed glibc 2.14 from source and have it on my LD_LIBRARY_PATH, so according to the answer here I need to install

libstdc++-4.9.x, which is compiled with glibc-2.14

unfortunately I cannot find that on rpmfind.

  • The object GLIBCXX_3.4.20 in libstdc++ version 4.9.x : Doesn't need to be compiled with a particular glibc version. The gcc-4.9.x available for EL6 was once compiled with a default RHEL6 ... and includes libstdc++ v. 4.9: /usr/local/gcc493/lib64/{ libstdc++.so -> libstdc++.so.6.0.20 }. You can point to this libstdc++.so.6, when running the applications. See 3) gcc49-c++-4.9.3 stackoverflow.com/questions/47175706/… – Knud Larsen Apr 25 '18 at 20:26
  • sorry I don't understand, when I strings /usr/lib64/libstdc++.so.6 I only find GLIBCXX_3.4.13 (the same in /usr/lib/ and also for libstdc++.so.6.0.13. I currently have libstdc++.so.6 on my LD_LIBRARY_PATH and get the error described above – tenticon Apr 26 '18 at 11:53
  • ? Who mentioned /usr/lib64/libstdc++.so.6 ? Download gcc49-c++-4.9.3-1.el6.x86_64.rpm. You can install the package with yum: # yum install Downloads/gcc49-c++-4.9.3-1.el6.x86_64.rpm ... or you can unpack the package, and use { libstdc++.so.6 -> libstdc++.so.6.0.20 } only.

  • @KnudLarsen thanks for clarifying. the download link for gcc49 is blocked for me. I have searched for 2h but didnt find gcc 4.9 source for el6 on sites that I could access. Is it somewhere on rpmfind or rpm pbone? – tenticon Apr 28 '18 at 16:18
  • gcc49-c++-4.9.3-1.el6.x86_64.rpm → Other link → dropbox.com/s/9dbj5jjwrk4iapz/… – Knud Larsen Apr 28 '18 at 16:45
