Мне нужна помощь относительно процесса сборки Zbar. Я пытаюсь перекрестно скомпилировать zbar-0.10 источник для платформы i.Mx6DualLite, и когда я даю приведенную ниже конфигурацию, X11 бросает ошибку «не может найти XvQueryExtension в -lXv!». Пожалуйста, помогите решить эту проблему. Я хочу запустить zbar-сканер на платформе i.Mx6DL с помощью приложения v4l2. X11 требуется, так как видео необходимо отображать на ЖК-экране.x11 проблема с сборкой zbar для платформы ARM

Пожалуйста, помогите. Я полностью этим занимаюсь.
Заранее спасибо С уважением Sarjoon
Ну, первый вопрос, который вы задаете, у вас есть * libXv.so на вашей целевой машине? –
Да, я проверил папку -L/home/user/Haji/ZBAR/Yocto/imx6dlsabresd/usr/lib/и Xv.so есть, и там есть все библиотеки X11. Но этот вопрос указывает на некоторые другие библиотеки, такие как «Расширение Xv». Нужно ли мне связывать любые команды, отличные от LDFLAGS? – sarjoon
OK Теперь вам нужно посмотреть config.log и увидеть точную ошибку. Возможно, configure не похвалил LDFLAGS. Или, возможно, libXv.so собирается для другой архитектуры. Или это может быть совсем другая ошибка (не неразрешенный символ). Также посмотрите, какая точная ошибка вызвала сообщение «проверка на X ... нет». –
