Apple Mach-O Linker Error

radmahdi commented 7 years ago

Thanks for the good work. However, I am getting linking error while compiling as below. Any suggestions would be appreciated.

@radmahdi thanks for the feedback and which branch are you testing?

Are you testing against the updated master branch?

The caffe2 v0.8.0 added support for METAL, which broke this project before.

My last commit should fix this and force the caffe to checkout to v0.7.0 which I think is stable and should not have this issue.

Could you clarify that?

radmahdi commented 7 years ago

Thanks for clarification. I had to update submodule after checking out to v0.7.0. So it solved the problem

KleinYuan commented 6 years ago

Seems a problem solved. If occur again, please reopen.

varunlakshmanan commented 6 years ago

@radmahdi @KleinYuan What submodule did you have to update? I'm still having this error. I am testing against the master branch (which checks out 0.7.0 by default) but the problem is still there.
