Я разрабатываю код, который будет работать в Linux с OpenCV и FFMPEG. Я хотел бы использовать свой Mac для разработки этого кода, и мне нужна функциональность FFMPEG на Mac.
Я смог запустить configure следующим образом:
./configure --without-quicktime --with-ffmpeg --without-python --disable-apps CPPFLAGS=-I/opt/local/include LDFLAGS="-L/opt/local/lib -L/usr/local/share -L/usr/local/lib"
но когда я запускаю make, я получаю эту ошибку:

Я попытался использовать более новую версию OpenCV, 1.1pre1, и я получил похожую ошибку, но с другими символами. Я использую тот же ./configure, как указано выше.

Если я добавлю --enable-shared = no и OpenCV скомпилируется, но тогда мои программы не запустятся ...
Есть ли какие-либо предложения о том, как заставить любой из них скомпилироваться со значением по умолчанию --enable-shared?
