Shipped DBoW2 package compilation error about badslam HOT 5 CLOSED

There was just a modification to the DBoW2 files related to BRIEF, maybe this adds some missing include: #50

If that does not fix it, have you tried updating the shipped version of DBoW2 to the latest official version? It seems like some inconsistency arose from the DLib/DBoW2/OpenCV versions that are present here.

Just wanted to add that I get the same issue. I've copied the new DBoW files across, but kept the included CMakeLists and I can progress in compiling. Still getting other compilation issues however I'll likely make separate tickets for those.

Using the DLib commit b6c28fb will solve the DBoW2 compilation problem. However, another compilation error that may relate to the flann arise as follows:

Is there any possible solution? Many thanks!

It appears as if some dependency on your system requires OpenMP, but it is not linked in. I would try to link OpenMP explicitly (-fopenmp compiler flag) and see whether that fixes it.

Hi, @puzzlepaint
Your are right. After revisiting this issue, I found that I'm compiling g2o with "-DG2O_USE_OPENMP=ON". Compiling with "OFF" flag will solve the problem.
