I'm replying here because it is more appropriate than the other thread.
I made some modifications to the build files:
FILE: ref_app/target/app/make/app_make.gmk
- removed the ".exe" from the commands to work on Mac command line.
- I get errors from the "HexManip.exe" make command. I assume it changes the Hex file, but I don't know what changes it makes. Is there a linux equivalent for this program?
FILE: ref_app/target/micros/avr/make/avr_flags.gmk
- Updated the GCC_VERSION, but it looks like those changes are already made on the latest code base.
Able to successfully compile the ref_app on a Mac using the avr-gcc tool-chain. Put together a ATmega328p reference circuit with an LED on a bread board and successfully flashed the hex file. The LED blinked, so I believe the program ran successfully.

Thanks for the information James.
Were you able to to use GNUmake in its native form on the mac for the ref_app?
Yes. The HEX manipulation program is yet another open issue. Its purpose is to manipulate HEX files via things like adding fill bytes, patching memory sections together, computing CRC and hash data integrity checks and putting them in code for ROM/RAM integrity checks, etc.
Eventually, I would like to replace the executable file with portable sources for HEX-manipulation.
Cheers, Chris.

Yes, I'm still using the GNU makefiles provided in the project with the following changes:
- Change paths from backslash to forward slash for Mac paths.
- Hard code of the TGT = avr (I am only interested in AVR at this time)
- Removed ".exe" from all targets for mac command line.
- Update of the paths for the linux targets unique to my mac system ("/usr/bin/" instead of "/bin/")
- Use of a later GCC_VERSION = 4.8.2
- Build gcc targets are named "avr-" instead of avr-unknown-". This is probably a Macports specific change.
Used the following build command:
make -f target/app/make/app_make.gmk rebuild
This build successfully with one error related to the HexManip.exe file:
make: tools/generic/hex_tools/HexManip.exe: Permission denied
make: [bin/ref_app_flash.hex] Error 1 (ignored)
Here is the git diff for these changes:

Hello Chris!
I'm using Windows but have a problem with hexmanip.exe too: it is missing and I can't figure out where to download it? Do I have to execute hexmanip.exe on the hex-file or can I comment this line out of app_make.gmk?
Thanks, Tom

Thanks Tom. Please just comment out the line. The presence of the line is actually a bug. Sorry, I thought had already corrected it. I will correct it next week. - Chris

The hex-manip line has been removed from the build script. But this breaks raspi and beagle bone builds of object binaries. Therefore, make a new issue for the creation of a new generic hex-manip facility.

The GNUmake scripts have been extended to include *nix compatibility. There are also new CMake scripts that probably run on the above-mentioned host.
