CC2650: Z stack application build error on IAR

Which IAR version do you use? If you build original CC2650 example, can you build it successfully?

I'm using 8.32.
I tried building the original sensortag application and got the same error.
Also, I tried building the application using IAR 7.4 but IAR failed to open the project file.

Ok so I reinstalled Z stack and built the 'SampleSwitch' example using IAR 7.40.2.

I get the following error :
Variable expansion failed for Pre-Build command line.
Offending text: ""$XDCROOT$/xs" --xdcpath="$XDCPATH$" iar.tools.configuro -c "$TOOLKIT_DIR$" --cc
"$COMPILER_PATH$" --device "$DEVICE$" --compileOptions $COMPILER_ARGS_ROOT_QUOTED$ --linkOptions
$LINKER_ARGS_QUOTED$ --profile release --projFile "$PROJ_PATH$""

Can you check what's on your IAR->Tools->Configure Custom Argument Variables?

I did as you said.
Now I get this -

Edit:
The last step says that I have to compile zstackcore.
Where is the project file for zstackcore?

You can switch to ZStackcore in Pro-ject workspace.

Thank you

But I am still not able to build the sample switch project
