GLIBCXX_3.4.11 not found when executing system('comand')

Hi all!

I am trying to execute a command with system() funciton for matlab. The command I want to use is a script that runs a c++ code.

When I open a terminal and use the command g2o -o out.g2o in.g2o it works perfectly and I get the output file that I want, but if I do system('g2o -o out.g2o in.g2o') I get the following error:

~/g2o/bin/g2o: ~/matlabR2010a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ~/g2o/bin/g2o)
~/g2o/bin/g2o: ~/matlabR2010a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ~/g2o/lib/libg2o_cli.so)

~/g2o/bin/g2o: ~/matlabR2010a/sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by ~/g2o/lib/libg2o_core.so)

And if I do strings libstdc++.so.6 |grep GLIBCXX i get the following:

GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7
GLIBCXX_3.4.8
GLIBCXX_3.4.9
GLIBCXX_FORCE_NEW

so it is really not there.

Some hint on what to do??

Thanks!!
