Errors when compiling code in WinARM

[kamejoko80]

Hi every body ! I interested in this page **broken link removed**
About building MP3 player only use the LPC2106 microcontroller
I've made this hardware and load the .hex file, wowww it had worked ok!
Now, I want to improve the software, by using the WinARM compiler in this page
**broken link removed**
First, I using the origin source code,
while compiling the source code, an error has occur, but I can't fix this problem, who had done with it please give some advances. I'm sorry, my english is rather pour!

Hmm...not enough information to answer the question. Could you provide what type of error you are getting?
