Pass in variable defined in makefile.defs

Hello

Given this makefile.defs (located in the project root directory)

$(info BEGIN makefile.defs) GIT_HASH := $(shell git rev-parse HEAD) # Determine the operating system ifeq ($(OS),Windows_NT) # For Windows, use PowerShell's Get-Date cmdlet GIT_DATE := $(shell powershell Get-Date -Format 'yyyy-MM-dd') RAW_GIT_AUTH := $(shell echo $(USERNAME) | sed 's/.*\\//') GIT_TIME := $(shell powershell Get-Date -Format 'HH:mm:ss') else # For Linux, use the date command and whoami GIT_DATE := $(shell date '+%Y-%m-%d') RAW_GIT_AUTH := $(shell whoami) GIT_TIME := $(shell date '+%H:%M:%S') endif # Check if the username is "jeff" and set GIT_AUTH accordingly # this is because Jeff has a mac, something something 10 foot pole ifeq ($(RAW_GIT_AUTH), jeff) GIT_AUTH := jefpot else GIT_AUTH := $(RAW_GIT_AUTH) endif # Check if the length of GIT_AUTH is greater than 6 ifeq ($(shell echo -n $(GIT_AUTH) | wc -c | awk '{print $1}'), 7) $(error Username is too long! Aborting build.) endif GIT_FLAGS += -DBECK_SOFTWARE_REVISION_GIT="$(GIT_HASH)" \ -DBECK_SOFTWARE_REVISION_DATE="$(GIT_DATE)" \ -DBECK_SOFTWARE_REVISION_TIME="$(GIT_TIME)" \ -DBECK_SOFTWARE_REVISION_AUTH="$(GIT_AUTH)" $(info GIT_HASH: $(GIT_HASH)) $(info GIT_DATE: $(GIT_DATE)) $(info GIT_TIME: $(GIT_TIME)) $(info GIT_AUTH: $(GIT_AUTH)) $(info END makefile.defs)

I want the GIT_FLAGS variable to be passed into the build command, so that BECK_SOFTWARE_xxx is defined through the macros.

I've followed the guide on this stack overflow post and had no luck. What do I need to do to get those defines include in the build?

I have verified that they are not passed in by looking at the console build output.

Hi @GUnderdown,

Please look into the following post by Erich Styger. I believe it will prove very insightful for your current inquiry: https://mcuoneclipse.com/2017/07/22/tutorial-makefile-projects-with-eclipse/

Let me know if it helps!

BR,
Edwin.

I managed to make this work by having a shell script that ran as a pre-build command, and generates the necessary defines in a .h file
