"undefined reference to" in MakeFile

Question

Я noob для MakeFile. Я прочитал все похожие записи в stackoverflow. Но все еще не знаю, как это сделать (я уверен, что это проблема MakeFile, потому что я могу запустить ее с помощью XCode). Вот мой Makefile и ошибки тзд:

####### Detect system architecture 

SYSARCH  = i386 
ifeq ($(shell uname -m),x86_64) 
SYSARCH  = x86_64 
endif

COMMONFLAGS = -Wall -Wextra -pipe -msse2 -Wno-reorder 
#-Werror 
####### Detect debug or release 

DEBUG   ?= 0 
CXXFLAGS   ?= 
ifeq ($(DEBUG), 1) 
    CXXFLAGS  += $(COMMONFLAGS) -DDEBUG -DOVR_BUILD_DEBUG -g $(DEFINES) 
    RELEASETYPE ?= Debug 
    LFLAGS   =

    CXXFLAGS  += $(COMMONFLAGS) -O2 $(DEFINES)

    LFLAGS   = -O1 # Why O1? 
endif

Я добавил:

-lopencv_core \ 
-lopencv_highgui \ 
-lopencv_imgproc \ 
-lopencv_video \ 
-lopencv_objdetect \ 

Теперь Ошибки:

ReadDataRunML класс добавлен себя. Как добавить его в MakeFile?

Answer 1

Вы должны добавить opencv библиотеки в список LIBS вы связать с:

Добавить в раздел LIBS вашего Makefile:

-lopencv_core \ 

и, в зависимости от того, какие функции вы используете OpenCV, вам может понадобиться один или несколько из следующих действий:

-lopencv_highgui \ 
-lopencv_imgproc \ 
-lopencv_video \ 
-lopencv_objdetect \ 

неразрешенные внешние просто потому, что компоновщик не знает, где искать их. Кроме того, убедитесь, что ваш путь к библиотеке opencv находится либо в вашем пути к lib, либо добавьте его в libpath, используемый компоновщиком. Вы можете добавить путь к библиотеке с опцией -L, например. -LMyLocalPathToOpenCV (вместо того, чтобы жестко программировать его там, где вы добавляете его в параметры компоновщика, вам, вероятно, захочется определить его и использовать макрос для ссылки на него, чтобы очистить ваш makefile, например $(OPENCV_LIB_PATH)).
