make: *** No rule to make target `.build/obj/GFXSRC.o'

[dswl]

Hello,

I'm trying to get one of the demos to work on OS X. I followed every step on the "Getting Started" page and created a `os_osx64.mk` file as suggested by inmarket in this post to compile on x64 OS X.

The make gives the following error:

make: *** No rule to make target `.build/obj/GFXSRC.o', needed by `.build/demotest.elf'.  Stop.

The C compiler options:

I modified the Makefile from `ugfx/boards/base/OSX` as follows:

I use uGFX 2.7 on OS X 10.11.6. `gfxconf.example.h` is copied to my project folder, renamed to `gfxconf.h` and further untouched.

I appreciate any help pointing me out to what I'm doing wrong.

Hello @dswl and welcome to the µGFX community!

The problem is caused by having GFXSRC and GFXINC in your Makefile there. Simply remove them and everything should work.
The Makefile you're using there is the high-level Makefile provided by the µGFX library. The $(GFXSRC) and $(GFXINC) variables mentioned in the documentation are already being included internally.

I hope that helps!

Thanks for your kind reply! Removing GFXSRC and GFXINC indeed removed the error, but unfortunately I ran into another problem.

As it is unrelated, I created a new thread here: 

 

I would appreciate your help.
