Mac OS c ++鏈接OpenCV和libtiff

[英]Mac OS c++ Link OpenCV and libtiff

問題描述

我最近寫了一個代碼來加載TIFF圖像（使用libtiff）並用opencv顯示（我知道opencv可以讀取tiff，但是我需要閱讀它才能獲得更底層的控制）。

當我剛剛使用libtiff閱讀TIFF並進行編譯時。 沒關系。 編譯命令如下： 

g++ -L /usr/local/lib/ -I /usr/local/include/ -ltiff libtiff_test.cpp -o libtiff_test

但是，當我將它們（OpenCV和Libtiff）放在一起時，就會出現問題。 編譯命令如下： 

g++ -L /usr/local/lib/ -I /usr/local/include/ -ltiff -lopencv_core -lopencv_highgui -lopencv_imgcodecs libtiff_test.cpp -o libtiff_test

編譯器報告以下內容：體系結構x86_64的未定義符號。

有人可以告訴我如何將這兩個庫組合在一起嗎？ 謝謝！

您沒有說您安裝了哪個版本的OpenCV（即版本2.x或3.x），也沒有說如何安裝（即從源代碼或使用homebrew ），也沒有說您如何構建它，也沒有顯示任何內容。代碼，因此任何答案只能是通用的。

通常，恕我直言，最簡單的方法是使用pkgconfig確定正確的包含文件路徑，庫路徑和庫。 因此，如果您使用自制軟件安裝了OpenCV版本2，則將執行以下操作以獲取包含文件路徑和庫： 

pkg-config --libs --cflags opencv

樣本輸出 

-I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib \
-lopencv_ml -lopencv_objdetect -lopencv_shape -lopencv_stitching  \
-lopencv_superres -lopencv_videostab -lopencv_calib3d             \
-lopencv_features2d -lopencv_highgui -lopencv_videoio             \
-lopencv_imgcodecs -lopencv_video -lopencv_photo -lopencv_imgproc \
-lopencv_flann -lopencv_core

並將其放在您的編譯命令中，如下所示： 

g++ ... $(pkg-config --libs --cflags opencv) ...

如果您安裝了OpenCV 3.x ，則可能需要 

pkg-config --libs --cflags opencv3

如果以其他方式安裝，則可能需要轉到從源代碼構建OpenCV的位置 ，然后找到pkgconfig文件，如下所示： 

find . -name \*.pc

然后可以針對該特定文件運行pkgconfig ，如下所示： 

pkg-config --libs --cflags $(find . -name \*.pc)

您可以對libtiff應用相同的邏輯。 首先，通過列出所有已知的軟件包並grepping tif找到pkgconfig用於libtiff的名稱： 

pkg-config --list-all | grep -i tif

樣本輸出 

libtiff-4                           libtiff - Tag Image File Format (TIFF) library.

現在，使用新發現的名稱（ libtiff-4 ）來獲取標志： 

pkg-config --libs --cflags libtiff-4

樣本輸出 

-I/usr/local/Cellar/libtiff/4.0.8/include \
-L/usr/local/Cellar/libtiff/4.0.8/lib -ltiff
