Compile error #1

Open jingpang opened 7 years ago

jingpang commented 7 years ago

Hi, i got the compile error below, do you have any advice? (Ubuntu 14.04 64bit, opencv3.2.)

And another question is about '* Not yet implemented indexing of images. '. Does this mean that it can not be used by ORB-SLAM for the moment (as it needs invert index from descriptor to image)?

Regards.

The problem is with the compiler version that is not allowing this type of definitions . Version g++ >5 solves the problem. It is somehow related to -fabi-version=6.
