I have seen this question asked before, but seems there was no answer.
I have installed flexus 4.0 with simics 3.0.31 hoping to use the couldsuite
benchmark.
Simics was able to run perfectly before installing flexus.
after installing flexus (it replaces libstdc++.so.5 with a symbolic link to
libstdc++.so.6)
runing Simics gives the following error message:
Failed to load module 'ppc440gp-turbo'
('/m/sda10/yarong/simics-3.0.31/amd64-linux/lib/ppc440gp-turbo.so'):
"version `CXXABI_1.2' not found (required by
/m/sda10/yarong/simics-3.0.31/amd64-linux/lib/ppc440gp-turbo.so)"
CXXABI_1.2 is contained within libstdc++.so.5. To solve this error, I
manually copied restore the original libstdc++>so.5.
However, when i run job to create check points using flexus, I got a
segmentation fault:

This gives me an impression that Simics and Flexus want different
libstdc++.so.5. Any ideas of how to solve the problem? Thank you!!!!
