Hi Guys,
During a debug biuld everything compiles fine, however when i set the build to Release i get this:

cannot find -lCMSISv1p30_LPC13xxAPD C/C++ Problem

Also, Whats the difference between the release and debug??

Cheers

That's a linker error message. It's complaining because it can't find CMSISv1p30_LPC13xx library.

Did you compile CMSISv1p30_LPC13xx in Release mode and is it opened?

Also a wrong setting in[INDENT]Properties -> C/C++ Build -> Settings -> Tool Settings -> MCU Linker -> Libraries
[/INDENT]is possible.

Debug and release mode are different settings to ensure correct settings for debugging (no optimization) and for release (optimization) :)

So check your settings (like symbols, includes, libraries...) for both configurations...

Also all included libraries has to be compiled in same mode before.

One of the difference is that by default the release build has the optimisation set at -Os while the debug has it set at -O0.

So it is likely that code will be "optimised" (I love that word) away if the compiler thinks that the code is useless. :D

In your case it seems that it cannot find the CMSIS. Are you really using v1.30 or the newer V2.0 in your project?

Maybe of not much help, I'm still trying to find my way with NXP chips. Anything for a fellow Sydney sider.  :)
