我正嘗試在Ubuntu 11.04上安裝Open-CV庫。使用ffmpeg安裝Open-CV時出錯
我遵循了InstallationGuide中的所有說明。
然而,隨着成功安裝後,我意識到,我沒有FFMPEG
的支持,因爲在我的配置文件FFMPEG
被禁用:
Video I/O:
-- DC1394 1.x: NO
-- DC1394 2.x: YES
-- FFMPEG: NO
-- codec: YES
-- format: YES
-- util: YES
-- swscale: NO
-- gentoo-style: YES
-- GStreamer: YES
-- UniCap: NO
-- PvAPI: NO
-- V4L/V4L2: Using libv4l
-- Xine: NO
所以我嘗試安裝FFMEPG的描述下here後重建一切。
與指令
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1
配置安裝後我跑make命令收到此錯誤:
make[2]: *** [bin/opencv_test_calib3d] Error 1
make[1]: *** [modules/calib3d/CMakeFiles/opencv_test_calib3d.dir/all] Error 2
make: *** [all] Error 2
這是編譯的錯誤所在出來的一點:

任何人都可以請告訴我安裝程序有什麼問題我在跟隨?
爲什麼存在此庫再分類錯誤?
谷歌搜索沒有什麼幫助,我發現了另一個鏈接錯誤,但由於不同的問題(https://code.ros.org/trac/opencv/ticket/1077)。你能幫我理解爲什麼構建過程沒有找到它正在尋找的庫嗎?我應該更新一些環境變量嗎?任何其他想法?很多! – Matteo 2012-01-09 10:28:58
也許我應該在'/etc/ld.so.conf.d'中添加一個文件來指定我安裝的x264和ffmpeg庫的路徑? – Matteo 2012-01-09 10:32:29
在安裝ffmpeg後執行** cmake **時,您是否能夠在輸出文本中看到它實際上找到了ffmpeg?在Google上快速搜索也發現其中一些符號包含在軟件包** libmp3lame0 **中,您是否安裝了它? – karlphillip 2012-01-09 11:29:47
