Ｈello, I have met a problem when I try to cross compile Tengine,

Does that means I need to cross compile Opencv at the same time ? Thanks a lot.

@ArtyZe

It looks like an ABI compatible issue. Are you trying to build tengine with toolchains for QNX?

Thanks

@cyberfire
First I want to compile it for linux, later I will try to compile a version for QNX, but I think maybe tengine rely on opencv to load and write image, so first need to cross compile opencv :(

@ArtyZe how to fix this compile issue finally？
