Проблема, выполняющая собственные функции OpenCV через JNI

Я пытаюсь запустить собственные функции OpenCV через интерфейс Java Native на Unbuntu. В конечном итоге то, что я пытаюсь сделать, это использовать функции bagofwords, доступные в стандартной версии OpenCV по умолчанию, но пока я пытаюсь проверить запущенные простые функции с помощью этого интерфейса.Проблема, выполняющая собственные функции OpenCV через JNI

Итак, у меня есть следующий файл Java с относительными встроенными функциями.

class OpenCVSample { 

static { 
    System.loadLibrary("Bridge1"); 
} 

public native int BridgeFunction(); 

public static void main(String[] args) { 
    OpenCVSample b = new OpenCVSample(); 
    b.BridgeFunction(); 
}

}

Вот мой C++ Bridge файл.

#include "OpenCVSample.h" 
#include <string.h> 
#include <cv.h> 

JNIEXPORT jint JNICALL Java_OpenCVSample_BridgeFunction(JNIEnv *env, jobject obj) {        
IplImage *img = cvCreateImage(cvSize(640, 480), IPL_DEPTH_8U, 1);            
    return 1; 
} 
int main(){}

Теперь, как я уже говорил, я делаю это на Ubuntu, поэтому я первый компиляции OpenCV в разделяемую библиотеку с JDK с gcc с помощью следующей команды.

g++ -shared -o libBridge1.so Bridge1.cpp -fPIC -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include/linux -I/var/opencv/opencv/include/opencv 
-I/var/opencv/opencv/modules/core/include 
-I/var/opencv/opencv/modules/imgproc/include 
-I/var/opencv/opencv/modules/features2d/include 
-I/var/opencv/opencv/modules/flann/include 
-I/var/opencv/opencv/modules/calib3d/include 
-I/var/opencv/opencv/modules/objdetect/include 
-I/var/opencv/opencv/modules/legacy/include 
-I/var/opencv/opencv/modules/highgui/include

Который затем создать общую библиотеку под названием libBridge1.so. Теперь проблема возникает, когда я пытаюсь запустить сам файл Java, где я получаю следующую ошибку.

java: symbol lookup error: /var/tests/oc/libBridge1.so: undefined symbol: cvCreateImage

Я смотрел в это совсем немного, и я почти уверен, что я правильно создать общую библиотеку, так что не могу понять, почему я получаю эту ошибку, может кто-нибудь объяснить?

----------------------------------- EDIT --- --------------------------------

Спасибо пользователям Andrew Henle и James Black за советы. Я пошел вперед и связал соответствующие библиотеки со следующей командой.

g++ -shared -o libBridge1.so OpenCVSample.cpp -fPIC -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include/linux -I/var/opencv/opencv/include -I/var/opencv/opencv/include/opencv -I/var/opencv/opencv/modules/core/include -I/var/opencv/opencv/modules/imgproc/include -I/var/opencv/opencv/modules/photo/include -I/var/opencv/opencv/modules/objdetect/include -L/var/opencv/opencv/build/lib -lopencv_core -L/var/opencv/opencv/build/lib -lopencv_imgproc -L/var/opencv/opencv/build/lib -lopencv_highgui -L/var/opencv/opencv/build/lib -lopencv_objdetect -L/var/opencv/opencv/build/lib -lopencv_features2d -L/var/opencv/opencv/build/lib -lopencv_video -L/var/opencv/opencv/build/lib -lopencv_core249

И библиотека кажется компилировать, однако этот вопрос в настоящее время кажется, что что он заполнен undefined references. При запуске команды ld на libBridge1.so я получаю следующий поток ошибок.

При запуске самого Java-файл, теперь я получаю эту проблему:

---------------------- ----------- EDIT 2 ------------------------------- -

После некоторого дальнейшего измельчения я нашел проблему с получением неопределенного значения r eferences. Я связывался с неправильным файлом ядра. Однако проблема все еще сохраняется, только в меньших масштабах.Вот следующая команда Im помощью:

g++ -Wall -shared-libgcc -Im -o libBridge1.so Bridge1.cpp -fPIC -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include -I/usr/lib/jvm/java-1.7.0-openjdk-amd64/include/linux -I/var/opencv/opencv/include -I/var/opencv/opencv/include/opencv -I/var/opencv/opencv/modules/core/include -I/var/opencv/opencv/modules/imgproc/include -I/var/opencv/opencv/modules/photo/include -I/var/opencv/opencv/modules/objdetect/include -I/var/opencv/opencv/modules/imgcodecs/include -I/var/opencv/opencv/modules/videoio/include -I/var/opencv/opencv/modules/highgui/include -L/var/opencv/opencv/build/lib -lopencv_core249 -L/var/opencv/opencv/build/lib -lopencv_features2d -L/var/opencv/opencv/build/lib -lopencv_imgproc -I/var/opencv/opencv/build/lib

В процессе компиляции теперь я получаю эту ошибку:

Bridge1.cpp: In function ‘jint Java_Bridge1_BridgeFunction(JNIEnv*, jobject)’: 
Bridge1.cpp:8:12: warning: unused variable ‘img’ [-Wunused-variable]

Вы должны связать свой общий объект с нужными «-l ...» Параметры , так же, как если бы вы компилировали обычный исполняемый файл C/C++ для запуска этой же функции.

Вы должны увидеть библиотеки, необходимые, если вы выполните «ldd libBridge1.so». Если вы не видите необходимые библиотеки, вам нужно добавить их на шаг ссылки.

Но это то, что я уже сделал, если вы посмотрите инструкцию компиляции, например: '-I/var/opencv/opencv/modules/core/include'. Кроме того, я запускал 'ldd' в библиотеке, он просто заявляет, что они« статически связаны » – Zy0n

Это включают в себя каталоги, используя -I (верхний глаз), а не -l (нижний регистр ell). Вам нужно добавить ссылки на команду связи для общих объектов, которые необходимы вашим общим объектам для запуска - точно так же, как если бы это был исполняемый файл. "-L/path/to/libs -lsomelib ...". Когда это будет правильно, если вы выполните «ldd -r libBridge1.so», вы не увидите никаких ошибок. –

-I сообщает компилятору, где ваши включенные, а не там, где нужны библиотеки для связи. ldd сообщит вам библиотеки, на которые вы ссылаетесь, но вы не связываетесь с ними. –

Я согласен с Эндрю Хени в отношении флага -l, так как мне любопытно, как компилируется ваша библиотека.

Но в вашем классе java вызовите System.loadLibrary(..), чтобы загрузить вашу библиотеку в первую очередь.

Тогда я ожидаю, что это не удастся, и с помощью команды ld будет полезно указать, что вам не хватает.

Запуск 'ld' возвращает следующее. 'ld: warning: не удается найти символ входа _start; не устанавливать начальный адрес libBridge1.so: неопределенная ссылка на 'cvCreateImage ' ' – Zy0n

И 'ldd' просто заявляет, что файл' статически связан' – Zy0n

Привет, Джеймс, я обновил основной пост с обновленными результатами после ссылки на соответствующие библиотеки. – Zy0n
