DEV C++ with CxImage (linker error)

Hello,

I would like to use the CxImage library in DevC++. (convert bmp to jpg)

I added the .lib to Project -> Project Options -> Parameters -> Linker: CxImage.lib, jpeg.lib

My Code is:

#include <windows.h>
#include "ximage.h"
#include "stdafx.h"
#pragma comment(lib,"CxImage.lib")
#pragma comment(lib,"jpeg.lib")


int main()
{
 CxImage image;

 // bmp -> jpg
 image.Load("d:\\image.bmp", CXIMAGE_FORMAT_BMP);
 if (image.IsValid())
 {
  if(!image.IsGrayScale()) image.IncreaseBpp(24);
  image.SetJpegQuality(70);
  image.Save("d:\\image.jpg",CXIMAGE_FORMAT_JPG);
 }

 // jpg -> bmp
 
    image.Load("d:\\image.jpg", CXIMAGE_FORMAT_JPG);
 if (image.IsValid())
 {
  if(!image.IsGrayScale()) image.IncreaseBpp(24);
  image.Save("d:\\image2.bmp",CXIMAGE_FORMAT_BMP);
 }


}
 // redimensionner + bmp -> jpg
 
    image.Load("d:\\image.bmp", CXIMAGE_FORMAT_BMP);
 if (image.IsValid())
 {
  image.Resample(1024/2,768/2,1,0);
  image.Save("d:\\imagesize.jpg",CXIMAGE_FORMAT_JPG);
 }

 return 1;
}

I got errores like these:

[Linker error] undefined reference to `CxImage::CxImage(unsigned long)'
[Linker error] undefined reference to `CxImage::Load(char const*, unsigned long)'
[Linker error] undefined reference to `CxImage::~CxImage()'
[Linker error] undefined reference to `CxImage::~CxImage()'

Also, if I delete the .lib in my proyect, and compile, gives the same error. It looks like the linker doesn't found the functions into the lib, or the lib is corrupted.


I found a code in: http://codes-sources.commentcamarche.net/source/22754-conversion-bmp-jpeg-avec-librairie-cximage where is the code with the .lib and the .exe (working okay).


Anyone could solve this problem? Thanks a lot guys
