Error configuring LPCXpresso v8.2.2

[johnygeorgemala]

I am trying to configure LPCXpresso v8.2.2, I tried in both Ubuntu and Windows. I am getting the same set of errors.

I am trying to build a project for LPC Chip 824.

I am getting this set of errors, from the LPC 824 Board Library. How can I fix it ?

How can I fix it ?

Hi George,

Please make sure you have imported the lpc_board and lpc_chip libraries to your workspace:

If they are already imported then delete them and import them again using the "Import projects" option from the Quick start panel:

You could also try using the LPC82x code bundle from the below page, you will need to import the common, peripherals and utilities projects:

Hope it helps!

Which other library should I include ? I have already included both board and chip libraries for Lpc 824. Moreover this error is coming from the lpv 824 board library.

You obviously have done something wrong, but I can't tell without seeing your project.

have you tried using the lpcopen examples, as is, and comparing the working projects with yours?

'undefined reference' is a linker error. You need to make sure you link with the appropriate library. 

Although you are not linking with a 3rd party library, this FAQ explains how libraries work.
