    C++NewerLib: .so.6.0.10
    I am trying to install Intel C++ Compiler and my system has: libstdc++.so.6.0.10.  But on step 4 the installation script says: missing critical pre-requisite: libstdc++.so.5.  It seems that I have a newer version.  So, how do I proceed?
    Thank you

    There is a separate forum for Intel C++, but you should find hints on this subject both here and there.
    First, there is a checklist in the installation notes, beginning with installing the g++ which corresponds with the icpc architecture you intend to install (Intel64 for x86_64 64-bit, ia32 for 32-bit),....  If your g++ is a recent version, you should be installing icpc 11.1.
    Exact prerequisites for Intel64 changed with icpc 11.0, with the change from 32-bit cross compiler to 64-bit native compiler.
    So, you may wish to go to the C++ forum and give more details about versions, if you are still stuck.  In case it will give hints, on this system I have
    $ rpm -qa |grep libstdc++
    compat-libstdc++-33-3.2.3-61
    libstdc++-4.1.2-42.el5
    libstdc++-devel-4.1.2-42.el5
    Creating a symlink from libstdc++.so.6 to libstdc++.so.5 (in both your 32- and 64-bit installations) has been known to work, in the case where you don't have an option to install something like compat-libstdc++.  This should not come up on a supported installation.  In RH 5.0 the menu option for that was missing, but it could be installed from the .rpm included in the distro.

    It would be better to install libstdc++.so.5. This library is required for both icc 11.x ia32 and Intel 64 bit versions. This is mentioned in icc release notes.

    Changes in major version number means incompatible code.
