Ошибки с загрузкой OpenCV в Ubuntu

Question

Я следовал этим инструкциям, чтобы загрузить OpenCV 3.1.0:

http://www.pyimagesearch.com/2015/06/22/install-opencv-3-0-and-python-2-7-on-ubuntu/

Однако, после того, как не выполнив команду make -j4 процессы кода до 14%, то результат выглядит следующим образом , давая ошибку в том, что существует фатальная ошибка math.h ...

Любые идеи? Заранее спасибо.

UPDATE: Я добавил math.h в PATH, и эта ошибка исчезла. Однако теперь я получаю сообщение об ошибке с помощью stdlib.h. Результат выглядит следующим образом.

л] Ошибка 2

Любые идеи? Благодаря!

ДРУГОЕ ОБНОВЛЕНИЕ: Я выполнил следующие инструкции: http://rodrigoberriel.com/2014/10/installing-opencv-3-0-0-on-ubuntu-14-04/ , в котором им требуется запустить файл sh, который они предоставляют. Однако ошибки продолжают сохраняться с помощью stdlib.h. Я неоднократно проверял, что stdlib.h является переменной окружения и что stdlib.h существует в usr/include. Файл ш выглядит следующим образом ...

Answer 1

Ну, это было долгое решение ... Кажется, что добавление переменной в PATH не было проблемой. Проблема была в G ++ и GCC версии 6. Поэтому после перенаправления gcc и g ++ на gcc и g ++ версии 5 все получилось.

Answer 2

Проблема с отсутствующими math.h файлом. make Цель цели cmath файл который включает math.h (строка 45 в cmath) файл. Как правило, вы найдете math.h в /usr/include/math.h.

Если его там, то для его работы вы можете добавить /usr/include в $PATH переменной окружения. Вы можете искать онлайн, чтобы добавить каталог в $PATH, или вы также можете проверить here.

Если его нет, вам необходимо найти файл в системе и указать его путь к цели make.
