Hello Ratheesh T,
You don't tell me what the code you are using? LPCopen? or SDK2.2?
If you are using the LPCopen, tell me the version.
It seems you are using the lpcopen code.
I have tried lpc5410x_xpresso54102_lpcxpresso_v3.03.000_16 which is downloaded from this link:
http://www.nxp.com/downloads/en/software/lpc5410x_xpresso54102_lpcxpresso_v3.03.000_16.zip
After build the lpc board and lpc chip library, then build the blinky, no error on my side.

Besides, my lpcxpresso IDE version is:

You need to download the latest lpcxpresso IDE:
LPCXpresso IDE v8.2.2|NXP
Have a great day,
Kerry
