无法从JNI调用C ++代码。代码在普通的C ++中运行，但是当我尝试从Java调用它时似乎有错误，我认为我正在编译/链接错误的东西。谁能发现什么是错的？
我正在使用arm-marvell-linux-gnueabi工具包进行交叉编译，以便在Beaglebone Black上运行代码。
这是我用于C ++代码的 Makefile ：
PORT = arm12
CFLAGS = -D__cplusplus -Wall -O
CPP=/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ -fPIC
CC=/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-gcc
INCPATH = -I./ -I../include -I./ -I../include -I/usr/lib/jvm/java-7-openjdk-amd64/include/ -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux
LIBS = -L../lib/$(PORT)
OBJS= FingerVerification.o
SRCS= FingerVerification.cpp
FDU03_TARGET = ../bin/$(PORT)/sgfplibtest_fdu03
FDU04_TARGET = ../bin/$(PORT)/sgfplibtest_fdu04
FDU05_TARGET = ../bin/$(PORT)/sgfplibtest_fdu05
all : $(FDU05_TARGET) $(FDU04_TARGET) $(FDU03_TARGET)
$(FDU05_TARGET) : $(OBJS)
$(CPP) /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu05 -lsgfplib -o $@ $(OBJS) $(LIBS)

$(FDU03_TARGET) : $(OBJS)
$(CPP) /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu03 -lsgfplib -o $@ $(OBJS) $(LIBS)
.cc.o :
$(CPP) $(FLAGS) $(INCPATH) -c $<
.c.o :
$(CPP) $(FLAGS) $(INCPATH) -c $<
.cpp.o :

dep :
gccmakedep $(INCPATH) $(SRCS)
clean :
rm -rf *.raw *.min $(OBJS) $(TARGET) core
rm -rf $(PORT)
mkdir $(PORT)
这就是C ++的编译方式：
/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ -fPIC -I./ -I../include -I./ -I../include -I/usr/lib/jvm/java-7-openjdk-amd64/include/ -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux -c FingerVerification.cpp
/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ -fPIC /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu05 -lsgfplib -o ../bin/arm12/sgfplibtest_fdu05 FingerVerification.o -L../lib/arm12
/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ -fPIC /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu04 -lsgfplib -o ../bin/arm12/sgfplibtest_fdu04 FingerVerification.o -L../lib/arm12
/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ -fPIC /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu03 -lsgfplib -o ../bin/arm12/sgfplibtest_fdu03 FingerVerification.o -L../lib/arm12
它输出FingerVerification.o以及我将不会与JNI一起使用的可执行文件（它们将运行原始C ++代码，但不应影响结果）。
编译代码并获取.o文件后，我想获取.so文件（动态库），所以我将其转换为：
/opt/arm-marvell-linux-gnueabi/bin/arm-marvell-linux-gnueabi-g++ /opt/arm-marvell-linux-gnueabi/arm-marvell-linux-gnueabi/libc/usr/lib/libusb.so -lpthread -lsgfpamx -lsgfdu03 -lsgfplib FingerVerification.o -shared -o libFingerVerification.so -L../lib/arm12 -lc
当尝试执行我的Java程序时，我在执行C ++程序的过程中遇到错误（当它尝试使用SDK中的资源时）。这是片段：
Call CreateSGFPMObject()
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0xb6302d3c, pid=1007, tid=3057566832
#
# JRE version: Java(TM) SE Runtime Environment (7.0_51-b13) (build 1.7.0_51-b13)
# Java VM: Java HotSpot(TM) Client VM (24.51-b03 mixed mode linux-arm )
# Problematic frame:
# C [libFingerVerification.so+0xd3c] initializeResources()+0x74
这是我的Java代码：
public class FingerVerification
{
static
{
System.loadLibrary("FingerVerification");
}
public static native BiometricResult verifyUser(String filePathTemplate1,
String filePathTemplate2);
public static native void registerUser();
public static void main(String[] args)
{
registerUser();
BiometricResult fingerResult = verifyUser("finger1.min", "finger2.min");
//According to research, device resolution effects results by 20%, weight is 2
//According to research, image quality based on acquisition area effects results by 73%, weight is 7.3
double weight = fingerResult.getImgQuality() * 7.3 + fingerResult.getResolution() * 2;
System.out.println("The weight is " + weight);
}
}
我的java代码能够成功调用C ++本机JNI方法：
JNIEXPORT void JNICALL Java_FingerVerification_registerUser
(JNIEnv *env, jclass thisClass)
此方法会快速调用initializeResources()，从而导致崩溃
以下是崩溃的C ++代码部分：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "sgfplib.h"
#include <sys/stat.h>
#include "FingerVerification.h"
LPSGFPM sgfplib = NULL;
SGDeviceInfoParam deviceInfo;
SGFingerInfo fingerInfo;
long err;
char function[100];
FILE *fp = NULL;
DWORD maxTemplateSize;
DWORD templateSize;
BYTE *templateToVerify;
BYTE *imgBuffer;
int initializeResources(void);
int main(int argc, char **argv)
{
}
int initializeResources()
{
//Creating the handle
strcpy(function,"CreateSGFPMObject()");
printf("\nCall %s\n",function);
err = CreateSGFPMObject(&sgfplib);
if (!sgfplib)
{
printf("ERROR - Unable to instantiate FPM object.\n\n");
return false;
}
printf("%s returned: %ld\n",function,err);
// Init()
strcpy(function,"Init(SG_DEV_FDU03)");
printf("\nCall %s\n",function);
err = sgfplib->Init(SG_DEV_FDU03);
printf("%s returned: %ld\n",function,err);
if (err != SGFDX_ERROR_NONE)
{
printf("ERROR - Unable to initialize device.\n\n");
return 0;
}
// OpenDevice()
strcpy(function,"OpenDevice(0)");
printf("\nCall %s\n",function);
err = sgfplib->OpenDevice(0);
printf("%s returned: %ld\n",function,err);
// getDeviceInfo()
deviceInfo.DeviceID = 0;
strcpy(function,"GetDeviceInfo()");
printf("\nCall %s\n",function);
err = sgfplib->GetDeviceInfo(&deviceInfo);
printf("%s returned: %ld\n",function,err);
if (err == SGFDX_ERROR_NONE)
{
printf("\tdeviceInfo.DeviceID : %ld\n", deviceInfo.DeviceID);
printf("\tdeviceInfo.DeviceSN : %s\n", deviceInfo.DeviceSN);
printf("\tdeviceInfo.ComPort : %ld\n", deviceInfo.ComPort);
printf("\tdeviceInfo.ComSpeed : %ld\n", deviceInfo.ComSpeed);
printf("\tdeviceInfo.ImageWidth : %ld\n", deviceInfo.ImageWidth);
printf("\tdeviceInfo.ImageHeight: %ld\n", deviceInfo.ImageHeight);
printf("\tdeviceInfo.Contrast : %ld\n", deviceInfo.Contrast);
printf("\tdeviceInfo.Brightness : %ld\n", deviceInfo.Brightness);
printf("\tdeviceInfo.Gain : %ld\n", deviceInfo.Gain);
printf("\tdeviceInfo.ImageDPI : %ld\n", deviceInfo.ImageDPI);
printf("\tdeviceInfo.FWVersion : %04X\n", (unsigned int) deviceInfo.FWVersion);
}
printf("\n");
}
请注意，它在打印时正确执行print语句
调用CreateSGFPMObject（）
因此，当它需要使用SecuGen SDK中的资源时，它正在执行该方法。这让我觉得我从FingerVerification.o对象文件中错误地生成了libFingerVerification.so文件。任何人都可以查看我的工作，看看是否有任何明显的问题？

好吧，我基本上放弃了这一点。而不是使用JNI我决定运行通过Java使用类似的方法编译本机C ++代码而创建的可执行文件：
Run C++ executable from Java in Linux
我打算只将参数传递给C ++代码的main方法，该方法将决定调用哪个函数，函数返回的任何结果都将保存到java程序可以读取的临时文件中，然后删除。 Hacky，但更简单，它应该工作。 C ++集成只是我被迫使用的系统的一小部分。
