Anybody have a linker script for the LPC1768?

I'm lost! Can't seem to find one. I'm modifying existing ones (LPC17xx) 
based on the memory in the 1768 and I can't get it to vector off and run 
code! I spent years working with the LPC2124 and LPC2138 and never had 
this problem! I developed entire UAV autopilots around these chips. In 
hindsight, I guess I had a good linker to start with because I never had 
to learn this part.

Or reading on this stuff? I'm willing to RTFM.

Examples including Linker-Scripts and startup codes are in the package 
"lpc17xx.cmsis.driver.library.zip" available from nxp.com

Please note that the examples for GNU might use some specials from the 
Codesourcery G++ Lite package (_start from library which seems to copy 
.data and init .bss before calling main()) and might not work with other 
precompiled packages of the GNU toolchain.

Well I got a hold of a similar download

but instead it was named:

"lpc17xx.cmsis.library.zip"

I couldn't get it to work. I'm going to try what you pointed me to now.

This section in make.rules.environment should be pointing to the header 
files, but the compiler is still puking on that.

FWLIB_DIR     =$(BUILD_ROOT)/$(FWLIB)
FWLIB_SRC_DIR =$(FWLIB_DIR)/source
FWLIB_INC_DIR =$(FWLIB_DIR)/include

I can go through and add full paths to the #includes to get past this, 
but I know that is not the right way.
