Why is build error

Hello,

could you post the exact error message from the console view?

Otherwise, have you tried to do a clean (see https://mcuoneclipse.com/2012/03/12/no-rule-to-make-target/) with Project > Clean already?

I suspect your make files are pointing to the wrong files.

I hope this helps,

Hello!

Thank you for your answer!

The error message image is as bellow:

As your said, the makefile is really source of error push! But I did not still know how to shoot the problem!

Have you followed the advise above?

And that screenshot does not really help. What would help is the content or report in the Console view.

The console view is as follow.

I have checked and found that the IDE link step pushes error .

But every one file build step is ok.

The OS of my computer is Windows 10 and KDS version is v3.2.0.

Hello guo,

Does your project ported from old version KDS to KDS v3.2 ?

Please replace -nanolibc with --specs=nano.specs --specs=nosys.specs     to have a try .

Please have a look  these thread :

unrecognized command line option '-nanolibc' 

Error1 unrecognized command line option '-nanolibc'
