ImportError: /home/user/Projects/sixdof/sixdof_env/lib/python3.6/site-packages/g2o.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZN3g2o17csparse_extension14writeCs2OctaveEPKcPK12cs_di_sparseb I'm using ubuntu 17.10

I don't know if this is related but I had trouble installing libqglviewer-dev:

Package libqglviewer-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libqglviewer-headers

I tried installing libqglviewer-headers, and also libqglviewr-dev-qt4. but to no avail. Any help would be greatly appreciated. Thanks

Same error on Python 3.7 with Debian 9.

Solved by disabling the CSparse extension building.
