Re: [Gems-users] Failed to load module 'ruby'

[May Zhao <zhao0043@xxxxxxxxxxxxxxxxxxxxxxx>]

Thank you for the replies. I resolved problem.
The problems is not because of SIMICS_EXTRA_LIB.
It is caused by GCC. 
Our system install the new GCC 3.4.6 and also libstdc++.so has been
changed.
I still used old GCC 3.2.3 to compile 
The error said:
Error loading module 'ruby': Failed to load module 'ruby' 
('/home/users/mayzhao/gems/simics_3_workspace/x86-linux/lib/ruby.so'):
"cannot open shared object file: No such file or
directory"

At first glance, I thought "ruby.so" was not right. However,
I use ldd ruby.so ,which told me : libstdc++.so.6 => not found.
So the reason is
libstdc++.so.6, not ruby.so

libstdc++.so.6 is required by GCC 3.4.6, but GCC 3.2.3 needs
libstdc++.so.5.

My conclusions:
If still want to use old gcc version, there are two places in which we
have to
check gcc and library path:
$GEMS/common/Makefile.common
$GEMS/ruby/module/Makefile
$GEMS/simics_3_workspace/compiler.mk
