Make Error: Make not recognizing commands in makefile

Hi,

Ive been making changes to the ODrive firmware and have consistantly been running into the issue where operators and commands in the makefile are not recognised. I am building this in windows with all the prerequisites installed and added to path.

When I run make from the command line, the following errors are thrown at me:

board version: v3.6-56V
Firmware version 0.5.2-dev (fw-v0.5.2-19-gc8b725b6*)
 [     ] 100%
'!' is not recognized as an internal or external command,
operable program or batch file.
'cp' is not recognized as an internal or external command,       
operable program or batch file.
make: *** [Makefile:35: all] Error 1

This happens regardless of whether I run the command in Powershell or Command Prompt.
While make does generate the necessary build files which i can flash with STM32CubeProgrammer, I am not able to run make flash, make clean without similar errors.

From my understanding ‘!’ and ‘cp’ are known to Powershell but not to Command Prompt, so is it possible make is using Command Prompt somehow even when it is run from powershell?? (doesnt sound right to me)

Here is a pic of the culprit lines of code in the makefile starting from line 37

Any help debugging this would be greatly appreciated

Hit me with a make --version

It is using version 4.3

Hmm… Open powershell through your start menu and try man cp

It tells me it is an alias of Copy-Item.

PS C:\Users\goodw> man cp
