build命令正确使用-stdlib = libstdc ++选项。

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

感谢您的帮助！





现在我发现我可以使用带-v选项的ld。
我不断调查。

 ld：未找到用于架构的符号x86_64 
 Machida-no-MacBook-Air：caffe machidahiroaki $ 
  
 
 
解决方案
已解决！
 
 
 
  cv :: imread ：String const& amp; int）定义在 libopencv_imgcodecs.dylib 和
 Makefile缺少它。
 
 
 
所以，我添加了 opencv_imgcodecs 到Makefile。
  LIBRARIES + = glog gflags protobuf leveldb snappy \ 
 lmdb \ 
 boost_system \ 
 hdf5_hl hdf5 \ 
 opencv_imgcodecs opencv_highgui opencv_imgproc opencv_core pthread 
  
 
I got this error for caffe build. How can I fix it?
I'm using Mac OSX Yosemite 10.10.1.

OpenCV libraries seem to be built with libstdc++, because the official install guide suggests so.

All the build commands are correctly with -stdlib=libstdc++ option.

Thank for your help in advance!






Now I find I can use ld with -v option.
I keep investigating.

 解决方案 
Solved!



cv::imread(cv::String const&, int) is defined on libopencv_imgcodecs.dylib and
Makefile is missing it.



So, I added opencv_imgcodecs to Makefile.
LIBRARIES += glog gflags protobuf leveldb snappy \
        lmdb \
        boost_system \
        hdf5_hl hdf5 \
        opencv_imgcodecs opencv_highgui opencv_imgproc opencv_core pthread



                        
这篇关于架构x86_64的未定义符号：用于caffe build的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
