在Mac 10.12（Sierra）上安裝Caffe時出錯「架構x86_64中找不到符號」

Question

我一直在嘗試在我的Macbook上設置Caffe三天，現在......也許你能幫助我嗎？

我跟着幾個教程包括這些：

• 官方伯克利視覺朱古力安裝指南
• https://gist.github.com/kylemcdonald/0698c7749e483cd43a0e
• https://eddiesmo.wordpress.com/2016/12/20/how-to-set-up-caffe-environment-and-pycaffe-on-os-x-10-12-sierra/

但每當我試圖運行

make all 

我得到這個錯誤：

LD -o .build_release/lib/libcaffe.so.1.0.0 

clang: warning: argument unused during compilation: '-pthread' 

Undefined symbols for architecture x86_64: 

    "cv::String::deallocate()", referenced from: 
    caffe::WindowDataLayer<float>::load_batch(caffe::Batch<float>*) in window_data_layer.o 

.............. 
.............. 
.............. 

ld: symbol(s) not found for architecture x86_64 

clang: error: linker command failed with exit code 1 (use -v to see invocation) 

make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1 

這裏是我所做的迄今：

• 我本來是在Mac OS 10.11埃爾卡皮坦用一個過時的Xcode（7.3）。爲了更新xcode，我不得不升級到Sierra（mac os 10.12）

• 我現在有xcode 8，但將xcode命令行工具降級到7.3.2。 （我不記得爲什麼，但它建議爲Caffe或CUDA）

• 我沒有NVIDIA圖形卡，但仍安裝CUDA（從我在線閱讀這是咖啡的先決條件）...我試圖CUDA 7（建議在伯克利視覺網站），目前CUDA 8
• 現在，我使用CUDA-8
• 我用自制在線推薦安裝OpenCV（OpenCV的2.4.13.2）
• 我使用openBLAS
• 我使用protobuf 3.3.0
• 我加opencv_highgui opencv_imgproc opencv_core opencv_imgcodecs到LIBRARIES in Makefile
• 我意識到鏈接器錯誤必須與libC++ vs libstdC++！我用otool -L手動檢查了各種依賴關係，看看是否仍有使用libstdc++，但似乎應該全部使用libc++構建。

任何提示或建議？ 請幫忙！

謝謝！

Answer 1

只是一對夫婦的提示和猜測。

• 這不一定是libC++/libstd ++不一致。
• opencv_imgcodecs僅在OpenCV 3+中可用，因此可能會造成一些問題。
• 如果您檢查了opencv庫，並且它們都鏈接到libc++，請檢查此命令是否爲ld -lopencv_highgui，並且對於其他庫也不會告訴您庫找不到。
• 另一件要檢查的事情是確保您只有一個 OpenCV安裝，有時一個衝突的副本可能會導致這些問題。
• 您也可以嘗試編譯一個獨立的OpenCV示例代碼，以確保這是Caffe的問題。
• opencv_imgcodecs僅在OpenCV 3+中可用，因此可能會造成一些問題。
• 最後一件事：刪除所有內容，啓用cpu only模式以擺脫CUDA依賴關係，此時使用最新版本的所有內容，具體爲：最新的Xcode命令行工具和OpenCV3。

在您的問題中發佈您的Makefile也會有幫助。

Answer 2

您可以設置LDFLAGS之前執行make all

$ LDFLAGS="`pkg-config --libs protobuf` `pkg-config --libs opencv`" $ make all
