Linker errors while JPEG compression

Hi,

I am working on Mac OS X 10.5.2, Xcode 3.1.2 version. One of modules of my application require JPEG compression technique, to accomplish, we are using the ijg sample ( provided in ipp-samples->image-codecs).

Below are the steps used

1. Compiled ijg sample (using build.sh)

2. Added libjpeg.ipp.a and libjpeg.ipp.dynlib created through this sample into our application


3. Added jconfig.h, jerror.h, jmorecfg.h, jpeglib.h and jversion.h from the include folder of ijg sample into our application.

The code on compilation gave following linker errors:

Our main purpose is to compress our raw data in JPEG format.

WHAT ARE THE MINIMAL SET OF LIBRARIES FROM INTEL IPP COMPILER PACKAGE TO COMPILE THE CODE SUCCEESSFULLY??

FYI: We have licensed version of Intel C++ compiler, and are using the same.

Thankyou.

You should report this on the IPP forum instead of the compiler forum.
