[Gems-users] Ruby/Opal "version 'GCC_4.2.0' not found" error

[David Bonavila <david.bonavila@xxxxxxxxxxxxxxxxxx>]

Hi.


After installing Simics (version 3.0.29) and compiling Ruby and Opal (GEMS 2.1) with gcc/g++ 3.4, I get the following error when I try to 'load-module' ruby or opal from Simics:

simics> load-module ruby                                                                                                 

Error loading module 'ruby': Failed to load module 'ruby' ('/opt/gems/simics_workspace/x86-linux/lib/ruby.so'): "version `GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6)"

The only "libstdc++.so.6" in my system is the one in "/usr/lib"

"libgcc_s.so.1" is in "/opt/virtutech/simics-3.0.29/x86-linux/sys/lib" and "/lib".

I have tried to copy libraries to /usr/lib: libsimics-common.so and libelf.so.0, as I read on this post: https://lists.cs.wisc.edu/archive/gems-users/2006-October/msg00003.shtml, but the error is still there.

I am running Ubuntu 8.04, clean install, and I have just installed "build-essential" and "gcc/g++ 3.4".

I don't have the environmental variable 
LD_LIBRARY_PATH set.

In this post (https://lists.cs.wisc.edu/archive/gems-users/2008-December/msg00067.shtml) a user says that he "used binaries (g++) and libraries (libstdc++.so.6, libgcc_s.so etc) from the newly installed gcc.3.4.6 directory to compile ruby and opal". Can anyone tell me how to do that??

Here I leave some information that can be useful for you to try to help me solve this issue:

Any help will be appreciated.

Thank you!!
