Java 通过JNI执行OpenCV本机函数时出现问题

我正试图通过Ubuntu上的Java本机接口运行本机OpenCV函数。最终，我试图实现的是使用OpenCV默认版本中可用的

BagoWords

函数，但目前我正在尝试使用此接口测试运行简单函数

因此，我有以下Java文件，其中包含相关的本机函数

class OpenCVSample {

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

public native int BridgeFunction();

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

}

这里是我的C++ <代码>桥< /COD>文件。< /P>

#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(){}

然后创建一个名为

libBridge1.so

的共享库。现在，当我尝试运行Java文件本身时，问题出现了，我得到了以下错误

java:符号查找错误：/var/tests/oc/libBridge1.so:未定义的符号：cvCreateImage

我已经对此做了很多研究，几乎可以肯定我创建的共享库是正确的，所以我不明白为什么会出现这个错误，有人能解释一下吗

感谢用户Andrew Henle和James Black的建议。我已经用下面的命令链接了相应的库

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

这个库似乎在编译，但是现在的问题似乎是它充满了

未定义的引用

。在

libBridge1上运行
ld
命令时，我得到以下错误流

在运行java文件本身时，我现在遇到了以下问题：

在编译过程中，我现在遇到以下错误：

您需要使用所需的“-l…”选项链接共享对象，就像您正在编译一个普通的C/C++可执行文件来运行相同的函数一样

如果执行“lddlibbridge1.so”，应该可以看到所需的库。如果您没有看到所需的库，则需要将它们添加到链接步骤。
我同意Andrew Henie关于
-l
标志的观点，因为我很好奇您的库是如何编译的

但是在java类中，首先调用
System.loadLibrary（..）
来加载库

然后我预计它会失败，使用
ld
命令将有助于指出您缺少的内容。
但如果您查看编译指令，这就是我已经做过的，例如：
-I/var/opencv/opencv/modules/core/include
。另外，我在库上运行了
ldd
，它只是声明它们是
静态链接的
那些是include目录，使用-I（大写字母眼），而不是-l（小写字母ell）。您需要为共享对象所需的共享对象添加对link命令的引用才能运行，就像它是一个可执行文件一样。“-L/path/to/libs-lsomelib…”。当它正确时，如果您执行“ldd-r libBridge1.so”，您将不会看到任何错误。-我告诉编译器您的include在哪里，而不是您需要链接到的库在哪里。LDD会告诉你链接到的库，但你没有链接到任何一个。我不完全理解如何去做这个，我以前从未真正做过C++的任何事情。现在我只需要使用OpenCV java端口中不可用的特定类。你能解释一下我是如何做到这一点的吗？OpenCV的文档中说了什么来链接一个要运行的可执行文件？“-L”和“-L”（大写和小写）选项？您需要将这些添加到您的gcc命令：gcc-L/path/to/libs-lOpenCV。。。（假设OpenCV库名为“libOpenCV.so”），运行
ld
返回以下内容<代码>ld:警告：找不到输入符号\u start；未设置起始地址libBridge1.so:对

cvCreateImage`和

ldd

的未定义引用只是声明该文件是静态链接的嗨，詹姆斯，我在链接相应的库之后用更新的结果更新了主帖。看起来你需要添加

-ldl-lpthread

和ippicv库，不管是什么。
