Build Issues

[kevindean87]

These are the errors I receive while trying to build (have you run into these before?):

Hi,
apparently in the official version on PCL they have changed this function, so my demo will not compile with the official PCL.

If you want to try this demo you can try to build my -modified- version on the PCL available here https://github.com/bellonemauro/pcl

Actually, what I have modified is only the svm_wrapper.h/cpp and svm.h/cpp so if you only take those file and merge into your pcl version it should work.
If you have the pcl installed (not build on your own) than you cannot do that. You need to build it.

I hope that will work.
M.

Ah, well that makes sense. I appreciate the help and the timely response. I will probably update the files like you said, because I have some changes (to hdl_grabber, point types, etc.) that I need to keep. Thanks again for the help! Appreciate it.

[kevindean87]

Thank you for the help. It DID end up working.

[bellonemauro]

good to know that the demo is useful!
