[Solved (debug mode)] built with qPCL, but MLS is 30x slower

Hi,

I successfully built the trunk 2.8 version with the qPcl plugin (the only activated plugin) on windows 7 x64, vs2013.

I used the "PCL 1.7.2 All-in-one Installer MSVC2013 x64" from http://unanancyowen.com/?p=712 and all the dependencies inside (eigen, boost, flann, vtk)

Everything works fine, but when I try to use the MLS smoothing command, it takes 5 minutes for the same command that takes 10 seconds to execute using the official build.

I also tried PCL 1.8 All-in-one with the same result.

Any idea is appreciated.

Thanks

Be sure to run CC in release mode (and not the default 'debug' mode which is great for debugging but awfully slow).

Yep, that's it exactly. I'm still new to c++ compilation. Thanks a lot.
