Eigen/Core: No such file or directory #86

Closed SDedf closed 6 years ago

SDedf commented 6 years ago

When trying to make g2o fork. I get a fatal error when the make is trying to include the Eigen/Core directory. I checked the /src/eigen/ directory and the Eigen folder is there. This maybe a simple fix. I checked to make sure the system eigen3 headers are in the /usr/include/eigen3/. I noticed the note of this will fail with errors if your are using the system eigen headers, where/how do I change this? Here is the exact output I received when executing the make command:

In order to avoid the issue, is to link the folders. Basically if you run into this issue run the line below: sudo ln -s /usr/include/eigen3/Eigen /usr/local/include/Eigen
