Patching failure

[lloydrayner]

Hi,

I have managed to build and run standard ORB-SLAM2. I am now trying to work within Python, I get a patching error on lines 119 and 477. Wondered if anyone knows what could be causing this?

[lloydrayner]

oh... I think I may have figured it out.

Am I supposed to apply the patch to all three files?

patch CMakeLists.txt < orbslam-changes.diff
patch include/System.h < orbslam-changes.diff
patch src/System.cc < orbslam-changes.diff

The patch certainly affects all three of those files. I was using git patch to affect them all at once (I assumed git would be available since it was cloned from github), but if this works, go for it.

I get the same issue? I followed the instructions and ran ~/slam/ORB_SLAM2$ git apply -v --ignore-whitespace orbslam-changes.diff and I get:

What am I doing wrong? It isnt as if the codebase changed, orbslam2 hasn't been updated in years! @jskinn could you please weigh in on this? Thank you
