    Navin,

    Please post the project settings XML from your project file.

    Note that the liblpc2000 libs are in the %APPDATA% now so you need to change some variables in your project to point to the right directory.

    Here is an example for the LPC1788/4088 for comparison. Works on CW 3.7 and 4.2:

    I don't spell out the eabi.a files directly in the project source.
