Hi I'm using STM32CubeIDE for my nucleol476rg board. I'm trying to compile the I-cube-lrwan stack with the Cube IDE. Currently, after compiling I'm getting an error - command-line>:0:1: error: macro names must be identifiers . Please help.

[MAust.1]

These are my error messages -

<command-line>:0:1: error: macro names must be identifiers

Look at the command line you're passing to the tools, perhaps the command line defines

Perhaps attach a project file, or the make file

I could solve it.

The additional '#' in -D#ARM_MATH_CM4 was the error

Thanks Clive for responding
