Re: [Gems-users] ruby/opal "version 'GCC_4.2.0' not found" error

[mehmetderin.harmanci@xxxxxxx]

  Hello,

   I had a very similar problem of loading ruby a few weeks ago when our
  system manager did an update on gcc. In my case, the problem was that
  ruby.so depended on some generic gcc module but it tried to use the copy
  of the module the simics installation directory instead of the one
  provided by the linux box. Since the module in simics installation (which
  came together with simics) was not updated with respect to the new update
  I got the same error as you did. So, for my case the solution was the
  following:

  1) I did the ldd on ruby.so (as you did below) and found out that it was
     trying to access module "libgcc_s.so.1" in the directory
     $SIMICS_INSTALLATION/x86-linux/sys/lib.

  2) I moved this module away form this directory.

  I guess this worked because the system was forced to look for the same
  library in its onw  gcc libraries and finding it there there were no
  conflicting dependencies left.

  I hope the above experience can help you,

      Best Regards,

         Derin Harmanci.
