use Debenu PDF library with eclipse CDT plugin

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I try to create JNI wrapper around the Debenu/PDF Library/DLL/Import/CPlusPlus.I use the CDT plugin for eclipse with MinGW for linking and compiling my code.
All the examples I've found are done with WinAPI. 
I try very simple thing:
com_mdm_mie_jniconnector_JniManager.H file:
#include <jni.h>
/* Header for class com_ricoh_mdm_mie_jniconnector_JniManager */

#ifndef _Included_com_mdm_mie_jniconnector_JniManager
#define _Included_com_mdm_mie_jniconnector_JniManager
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class:     com_mdm_mie_jniconnector_JniManager
 * Method:    ping
 * Signature: ()Z
 */
JNIEXPORT jboolean JNICALL Java_com_mdm_mie_jniconnector_JniManager_ping
  (JNIEnv *, jobject);
#ifdef __cplusplus
}
#endif
#endif
=================
com_mdm_mie_jniconnector_JniManager.CPP file:

#include "com_ricoh_mdm_mie_jniconnector_JniManager.h"

#include "DebenuPDFLibraryDLL1016.h"
#include <string>
#include <iostream>

using namespace std;

/*
 * Class:     com_mdm_mie_jniconnector_JniManager
 * Method:    ping
 * Signature: ()Z
 */
JNIEXPORT jboolean JNICALL Java_com_mdm_mie_jniconnector_JniManager_ping
  (JNIEnv *env, jobject obj)
{
	//create the library and release it
	// Declare and load Quick PDF Library DLL
	std::string str = "DebenuPDFLibraryDLL1016.dll";
	std::wstring temp(str.length(),L' ');
	std::copy(str.begin(), str.end(), temp.begin());

	DebenuPDFLibraryDLL1016 QP(temp);

	 return JNI_TRUE;
}

Error is:
>undefined reference to `DebenuPDFLibraryDLL1016::DebenuPDFLibraryDLL1016(std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)'

I tried:

DebenuPDFLibraryDLL1016 QP("DebenuPDFLibraryDLL1016.dll");
> no matching function for call to 'DebenuPDFLibraryDLL1016::DebenuPDFLibraryDLL1016(const char [28])'

DebenuPDFLibraryDLL1016 QP(L"DebenuPDFLibraryDLL1016.dll");
>undefined reference to `DebenuPDFLibraryDLL1016::DebenuPDFLibraryDLL1016(std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)'

I did not find a way to link and compile the DebenuPDFLibraryDLL1016 into my application (which is dll).
Here is the command I use:
g++ "-IC:\\Program Files\\Java\\jdk1.7.0_21\\include" "-IC:\\Program Files\\Java\\jdk1.7.0_21\\include\\win32" "-IC:\\Program Files (x86)\\Debenu\\PDF Library\\DLL\\Import\\CPlusPlus" -O0 -g3 -Wall -c -fmessage-length=0 -o com_mdm_mie_jniconnector_JniManager.o "..\\com_mdm_mie_jniconnector_JniManager.cpp" 
g++ -shared -o libwinwrapper.dll com_mdm_mie_jniconnector_JniManager.o 

For now it seems I can not create the const std::wstring as it is declared by the constractor:
DebenuPDFLibraryDLL1016(const std::wstring& dllFileName);

Please help.

	I tried the following: std::wstring lib; lib.append(L"DebenuPDFLibraryDLL1016.dll"); DebenuPDFLibraryDLL1016 QP(lib); still no luck: >> C:\Tmp\Osgi\winwrapper\Debug/../com_mdm_mie_jniconnector_JniManager.cpp:37: undefined reference to `DebenuPDFLibraryDLL1016::DebenuPDFLibraryDLL1016(std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)' C:\Tmp\Osgi\winwrapper\Debug/../com_mdm_mie_jniconnector_JniManager.cpp:37: undefined reference to `DebenuPDFLibraryDLL1016::~DebenuPDFLibraryDLL1016()' collect2.exe: error: ld returned 1 exit status

	I believe that the problem is linking the dll's into my project. Here's the steps I did: 1. copied C:\Program Files (x86)\Debenu\PDF Library\DLL into C:\Debenu directory, so the path does not have any white spaces. 2. created the following link command: g++ "-LC:\\Debenu\\DLL" -shared -o libwinwrapper.dll com_ricoh_mdm_mie_jniconnector_JniManager.o -lDebenuPDFLibraryDLL1016 I did it according to the following page: http://www.mingw.org/wiki/Specify_the_libraries_for_the_linker_to_use Unfortunately it still does not work. I got the following error: C:\Tmp\Osgi\winwrapper\Debug/../com_mdm_mie_jniconnector_JniManager.cpp:37: undefined reference to `DebenuPDFLibraryDLL1016::DebenuPDFLibraryDLL1016(std::basic_string<wchar_t, std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)' C:\Tmp\Osgi\winwrapper\Debug/../com_ricoh_mdm_mie_jniconnector_JniManager.cpp:37: undefined reference to `DebenuPDFLibraryDLL1016::~DebenuPDFLibraryDLL1016()' collect2.exe: error: ld returned 1 exit status Can I find the setting for the C++ debenu dll libraries ? Should I include both: DebenuPDFLibrary64DLL1016 and DebenuPDFLibraryDLL1016 with *"-l"* option ? Should I include the directory "-L" option ?

	Found my problem. Add the * DebenuPDFLibraryDLL1016.cpp * DebenuPDFLibraryDLL1016.h into your project. Do not just include them in the compiler , but physically copy them in the same dirsctory. PS: during compilation it gives hundreds of warnings: "warning: deprecated conversion from string constant to ‘char*’" you will have to add the following option to compiler to suppress them all: -Wno-write-strings Regards

use Debenu PDF library with eclipse CDT plugin

"warning: deprecated conversion from string constant to ‘char*’"

you will have to add the following option to compiler to suppress them all:
