#131 Example makefiles fail on mac,

[A Wiebe]

Broken
ASFLAGS := -g $(ARCH)
LDFLAGS = -specs=ds_arm9.specs -g $(ARCH) -Wl,-Map,$(notdir $*.map)

Change to this and it works( a global replace probably inadvertantly altered this it worked in previous versions)

ASFLAGS := -g $(ARCH)
LDFLAGS = -specs=ds_arm9.specs $(ARCH) -Wl,-Map,$(notdir $*.map)

base_rules does not EXPORT a linker, so the I think a native ld is used. The Darwin ld does not recognize the -g flag, but removing it seems to work

tried exporting LD=$(prefix)ld

The armeabi-ld doesn't seem to know how to link arm-thumb

$make

[ -d build ] || mkdir -p build
make --no-print-directory -C build -f /opt/devkitPro/examples/nds/Graphics/3D/3D_Both_Screens/Makefile

This makes no sense.

The linker changes between g++ & gcc depending on the existence of C++ files in the project

ifeq ($(strip $(CPPFILES)),)
export LD := $(CC)
else
export LD := $(CXX)
endif

I test the examples regularly on OSX, they work for me. Obviously there's some difference between your installation and mine.

Usually these things turn out to be pollution of the environment with variables intended for native compilers.

Seems to have been an artifact of when DEVKITPRO was in /opt/devkitpro
Indeed, environment variables were conflicting.
Very strange resulting behaviour, would never have guessed that was the issue.
Thanks, issue resolved.
