I'm trying to compile HelloWorld Demo by Eclipse on Win 10,  following the instructions in

But I receive an error at linking step:


17:24:29 **** Incremental Build of configuration Default for project Helloworld_demo ****

The strange thing is that QCLI_demo, with the same settings and configurations, is compiled and debugged without problem. 

Any idea about ?

Thanks in advance

From the logs we observe as below :

IOError: [Errno 2] No such file or directory: '..\\..\\..\\..\\..\\bin\\cortex-m4\\threadx\\DefaultTemplateLinkerScript.ld'
> the issue is due to invalid path whiletrying to build Helloworld_Demo. Make sure the build command is executed from build/ms

Can you confirm the same behaviour with command prompt build ?
