I am trying to get one of the demos to work on OS X. The object files are finally linked, but can not be successfully transformed from an ELF into an executable file. objcopy fails with Creating .build/demotest.hex objcopy: .build/demotest.hex: address 0x00000001000016b0 out of range for Intel Hex file objcopy:.build/demotest.hex: Bad value My Makefile is ugfx/boards/base/OSX/example with GFXLIB set, but OPT_OS is set to osx64 as suggested in this post. As objcopy does not ship with OS X by default, I installed it via homebrew (GNU objcopy 2.29) as it seemed to be required by make. I use uGFX 2.7 on OS X 10.11.6. I appreciate any help. Regards

Thank you for pointing this out. The GFXDEMO variable was totally out of my view...

Thank you very much. This solved this problem. To my defense, I'm quite new to make. Unfortunately my series of problems with compiling this demo doesn’t stop. Could you please have a look at the follow up problem I described here?

I’m still trying to get one of the demos to work on OS X. Unfortunately I get a duplicate symbol error, but strangely for just one file. duplicate symbol _main in: .build/obj/GFXLIB/demos/modules/gdisp/basics/main.o ld: 1 duplicate symbol for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [.build/demotest.elf] Error 1 The linking ultimately fails. There is no other file than the modified example makefile from `ugfx/boards/base/OSX/example` in the project folder: No second main.c or any other custom file I wrote containing the main symbol.

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.

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. Unfortunately ld yields errors about many ignored files that were built for i386 instead of x86_64. ld: warning: ld: warning: ignoring file .build/obj/GFXLIB/src/gfile/gfile_fs_native.o, file was built for i386 which is not the architecture being linked (x86_64): .build/obj/GFXLIB/src/gfile/gfile_fs_native.oignoring file .build/obj/GFXLIB/src/gfile/gfile_fs_ram.o, file was built for i386 which is not the architecture being linked (x86_64): .build/obj/GFXLIB/src/gfile/gfile_fs_ram.old: warning: The linking ultimately fails.
