[U-Boot] Cross-compiling U-Boot on Mac OS X -- can't find crc32.c?

[Timur Tabi]

I'm trying to cross-compile U-Boot on a Mac OS X system, which is
BSD-like.  I have a toolchain already created - I've been able to
compile the Linux kernel with no problems.  I figured U-Boot would be
easier, but instead it's doing a lot of weird stuff.

So when I run "make", I get this:

$ make ARCH=ppc
for dir in tools examples api_examples ; do make -C $dir _depend ; done
make[1]: Nothing to be done for `_depend'.
make[1]: Circular hello_world.c <- hello_world.c dependency dropped.
make[1]: Circular sched.c <- sched.c dependency dropped.
make[1]: Circular stubs.c <- stubs.c dependency dropped.
make[1]: Circular ppc_longjmp.S <- ppc_longjmp.S dependency dropped.
make[1]: Circular ppc_setjmp.S <- ppc_setjmp.S dependency dropped.
make[1]: Nothing to be done for `_depend'.
make[1]: Nothing to be done for `_depend'.

make: *** [tools] Error 2

crc32.c is in lib_generic/, but the current directory is tools/, so
I'm not surprised it doesn't compile.  Has anyone tried this before?
What am I missing?

IIRC this is fix on the Mainline

to compile on Mac OS you will have to move to the laster Mainline ,
fix the lib_ftd endian.h and byteswap.h does not exist on MAC OS X IIRC
and fix the _depend Makefile target
I've start to fix it but never find time to finish (some patch are already
mainline)

Is this "make" a GNU make? Which version?

GNU Make 3.81

I've searched the archives for this mailing list, and I see that this
issue comes up every now and then, but never with any resolution.  If
I could just get mkimage compiled, that would be okay for now.  But
according to Jean-Chrisophe's email, it looks like this would be not
be trivial to fix.

That's what I've been using, and that's what's broken.

Well, I tried to fix it, but I can't figure it out.  I just don't
understand why it's so broken.  The errors I get are so confusing, and
I can't figure out what the Makefile is doing when it fails.  So I
give up.

Fortunately, I found a version of mkimage that builds just fine as-is,
and that's all I care about for now.  If anyone else is interested,
you can find it here:

http://packages.debian.org/sid/uboot-mkimage

Just download the tarball and run 'make'.

Wolfgang, I think you seriously need to revamp your build process.
The kernel is orders of magnitude more complex than U-Boot, and yet I
can build it just fine on OS X.

Hm... Do I? It works fine for me...

It's you who has OS X, and who has a problem. Only when Ah itchez, Ah

Just so I'm clear on this, you're saying that you're not really
concerned about how well U-Boot works for other people?

No, people that aren't running OS X cannot debug problems that happen 
when running on OS X.

That sounds like you want Wolfgang to fix a problem he doesn't have and 
cannot reproduce, since he isn't running OS X (to the best of my knowledge).

No, what I really want is the build process to be simpler so that other people can fix problems with it.  I don't even understand how it works when it *does* work.  

A functioning build process on OS X will allow me to do more work on U-Boot, adding more features and fixing more bugs, than I normally would be able to do.  But I can't fix every problem myself.

again, that is your itch to scratch.  people who are doing significant amount 
of work in u-boot have no problem with it as it exists now.

this is open source.  if you are unwilling or unable to do the work, i imagine 
there are plenty of people out there willing to take your money and do it for 
you.
