Ошибка при установке Open-CV с помощью ffmpeg - PullRequest
3 голосов
/ 07 января 2012

Я пытаюсь установить библиотеку Open-CV, работающую на Ubuntu 11.04.

Я следовал всем инструкциям, найденным в InstallationGuide .

Однако после установки сУспех Я понял, что у меня нет поддержки FFMPEG, потому что в моем файле конфигурации FFMPEG было отключено:

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

Поэтому я попытался восстановить все после установки FFMEPG, как описано здесь .

После настройки установки с инструкцией

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1

я выполнил команду make, получив эту ошибку:

make[2]: *** [bin/opencv_test_calib3d] Error 1
make[1]: *** [modules/calib3d/CMakeFiles/opencv_test_calib3d.dir/all] Error 2
make: *** [all] Error 2

Это точка компиляции, где ошибкавыходит:

Может кто-нибудь сказать, пожалуйста, в чем проблема с процессом установки, за которым я слежу?

Почему возникает ошибка ссылки на библиотеку?

Эти ошибки происходят из процесса компоновки, и они часто означают, что вам не хватает некоторых библиотек в вашей системе, или они находятся в месте, которое не ищется процессом сборки.

Я предлагаю вам Google эти символы, чтобы знать, какие пакеты вам нужно установить.

EDIT:

Подводя итоги чата, который у нас был наедине, основной проблемой было статическое построение x264. Необходимо создать совместно используемую версию библиотеки с --enable-shared. ФП рекомендует добавить --prefix=/usr/local во всех параметрах конфигурации.
