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

[David Bonavila <david.bonavila@xxxxxxxxxxxxxxxxxx>]

Hi again.

I finally solved this problem. I tell you what I did, as someone might have the same problem in the future.

It is a problem of libstdc++6 with gcc-3.4 (libstdc++6 is too new).

So I downloaded the package "libstdc++6_3.4.3-13_i386.deb" (from http://www.filewatcher.com/m/libstdc%2B%2B6_3.4.3-13_i386.deb.321084.0.0.html)and installed it with "dpkg -i libstdc++6_3.4.3-13_i386.deb".

I did "make clean" and compiled Ruby and Opal again (using gcc/g++ 3.4) and now I can do "load-module" for both Ruby and Opal from Simics with no problem at all.

Thank you anyway.

Regards,

David

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:
