Ký hiệu không xác định cho kiến ​​trúc x86_64: để xây dựng caffe

Question

Tôi gặp lỗi này khi xây dựng caffe. Làm thế nào tôi có thể sửa chữa nó? Tôi đang sử dụng Mac OSX Yosemite 10.10.1.

Tất cả lệnh xây dựng đều đúng với tùy chọn -stdlib = libstdC++.

Machida-no-MacBook-Air:caffe machidahiroaki$ make -n | grep clang | grep -v stdlib=libstdc++ 

Cảm ơn sự giúp đỡ của bạn trước!

Bây giờ tôi thấy tôi có thể sử dụng tùy chọn ld with -v. Tôi tiếp tục điều tra.

Đã giải quyết!

cv::imread(cv::String const&, int) được xác định trên libopencv_imgcodecs.dylib và Makefile bị thiếu.

Vì vậy, tôi đã thêm opencv_imgcodecs vào Makefile.
