Hi Linto,
Yes pre-compiled library is free. Please visit emWin page at
http://www.lpcware.com/content/project/emwin-graphics-library

BSP packages show how to integrate library.

You can also look into porting guide at

Hi lintovincent88,

When you download and install the pre-compiled EmWin libraries, you should have path such as "C:\NXP\EmWin\" on your computer. In this folder should contain the library that you should include in your project, as well as an emWin_header folder. Copy this entire folder into a directory close to your project and make sure you change your compiler settings to include a path to this folder. All of the source files inside this folder is needed for EmWin.

You need to add the library, itself, to you link options.

hi.,

thanks for your reply., i think the library got linked, the old errors are not showing now.,but the new problem is RAM location overflow. why is it so? how can i solve this ?

This is the error i got :

You are trying to link >2Mb of data (your images?) :
1. That is not going to fit in 64K of RAM, however hard you try
2. Regardless of RAM, it is not going to fit into the on-chip flash either (it copies from Flash to RAM at
startup - which you probably wouldn't want to do for image data anyway)

I think you need to go back to the drawing board on what you are trying to do.
