make error about g2o

[cumtchenchang]

I have tried cc@cc-K55VD:/usr/local/lib$ sudo ln -sv libg2o_csparse_extension.so libg2o_ext_csparse
, but the error is still on.

sudo ln -sv /usr/local/lib/libg2o_csparse_extension.so /usr/local/lib/libg2o_ext_csparse.so

This is caused probably by an old version of g2o. Now g2o has updated this lib name to libg2o_csparse_extension.so while pl-slam used out-dated one.
