Problem building on OS X

[Anonymous]

Hi,

I'm having some trouble building on OS X. The error I'm getting is below. I
see g++, make, and libpng3-dev are dependencies and I think I have them
installed.

On libpng3-dev, I have the latest version available in fink:

spocker:waffles andrew$ fink list -i | grep png

i libpng15-shlibs 1.5.10-1 Shared libraries for libpng15 package

i libpng3 1:1.2.49-1 PNG image format handling library

i libpng3-shlibs 1:1.2.49-1 Shared libraries for libpng3 package

i system-pkgconfig-cairo-png 1.10.2-1

i system-pkgconfig-libpng 1.5.4-1

i system-pkgconfig-libpng15 1.5.4-1

g++ is Apples C++:

$ g++ -v

Using built-in specs.

make is there too:

Any idea what might be going wrong?

Thanks!

Unfortunately, I don't actually have a Mac, so I probably can't be very
helpful. Anyone out there know the answer to this?

According to this forum (http://forums.nvidia.com/index.php?showtopic=105940&
st=20), the
solution might be to add an "s" to the flags used by "ar". More specifically,
open waffles/src/GClasses/Makefile, and change line 168 from

@ar -cr $(TARGET_PATH)/$(TARGET_NAME_OPT) $(OBJECTS_OPT)

to

@ar -crs $(TARGET_PATH)/$(TARGET_NAME_OPT) $(OBJECTS_OPT)

. If that fixes it, please let me know, and I will update it in our
repository.

I ported Waffles to OSX using the 32-bit machines that my department used to
provide. Unfortunately, they closed the mac lab because few people used it.
I'll see if I can get access to a 64-bit mac in the near future, but I'm out
of town right now, so I won't be able to try it for some time. Good luck!

Mike: Thanks a bunch. That seems to have fixed the problem since it builds now
and all the demos I've tried are working.

I think I'm in business.

Thanks!
