malloc(): memory corruption #34

Closed CydKnocking closed 4 years ago

CydKnocking commented 5 years ago

I've successfully installed g2o on Python 3.6.8 following the instructions. But when I import g2o, the following error occurred: >>> import g2o malloc(): memory corruption Aborted (core dumped) and my python exits automatically. I'm using Ubuntu 18.04.1 as a virtual machine on my computer. Is it an issue related to my system or just a bug in g2opy?

What's more, now I switched to Ubuntu 16.04.3 and successfully installed g2o on Python 3.5.2. However, an Segmentation fault occurred when I import g2o: >>> import g2o Segmentation fault (core dumped) and python exits automatically again. When I installed g2o at the last step in the instructions, there's the information shown in the terminal: $ sudo python3.5 setup.py install running install copying ./lib/g2o.cpython-35m-x86_64-linux-gnu.so -> /usr/lib/python3/dist-packages Is there something about python3 or python3.5? But there's no folder named dist-packages under python3.5...

Try install package "libqglviewer-dev-qt4", then rebuild g2o and g2opy.

Thanks a lot. I got the wrong way to rebuild g2opy...
