Warning: this is draft!

I try to put here my notes on setting up OpenMoko environment (Qemu and MokoMakefile) on Mac OS X.

Contents

Introduction

Some time ago I ask if anyone has ever set up OpenMoko environment on MacOS X. No one has answered that he did but several people were interested. So I deceided to wrote some directions on how to do that.

As for now I was not successful but I am still trying ;)

Setting up environment

Prequisites

Install fink and darwinports (both have neccesary packages)

Follow instructions on: http://www.openembedded.org/wiki/BuildOnOSX to set up OE environment.

You can get mentioned packages using darwinports:

sudo port install quilt
sudo port install py-psyco
sudo port install cogito

Then get Q[kju] project: http://www.kju-app.org/proj/wiki/CompilingQ into /Volumes/OE/Q but do not compile it yet (run only "prepare the sources"). This will be needed for compiling Neo1973 emulator.

Set up environment as described in MokoMakefile:

cd /Volumes/OE
mkdir moko; cd moko
wget http://www.rwhitby.net/files/openmoko/Makefile

make setup

Making developers image

make openmoko-devel-image


Patching qemu-neo1973

The main idea is to get patches for gcc-4.x from Q project and apply it to qemu-neo1973 branch. I'm still working on it.

Building emulator

TODO

Personal tools

Warning: this is draft!

I try to put here my notes on setting up OpenMoko environment (Qemu and MokoMakefile) on Mac OS X.

Here goes my mail to openmoko mailing list in which I described common problem while compiling qemu on Mac:

There was some discussion on the lists some time ago and I wanted to
check if anything has changed.

I've made some quick research on subject of developing OpenMoko apps
on MacOS X. It appears that we could run MakoMakefile:

http://www.quantum-step.com/download/OpenMoko-Edition/oe

That's great!

I checked if there is any possibility to run QEMU's Neo1973 port on
Mac but it seems not possible right now. Compiling it as written on
http://wiki.openmoko.org/wiki/OpenMoko_under_QEMU does not work
because it requires gcc-3.3 which seems to be broken on MacOS -
http://lists.macosforge.org/pipermail/macports-users/2007-February/001593.html

Compiling ends up with error: gcc-3.3: installation problem, cannot
exec `cc1': No such file or directory

Compiling neo1973 qemu with gcc-4.0: ./configure
--target-list=arm-softmmu --cc=/usr/bin/gcc-4.0 --disable-gcc-check

gives you:
dyngen.c: In function 'gen_code':
dyngen.c:1853: error: 'struct relocation_info' has no member named 'r_offset'
dyngen.c:1854: error: 'struct relocation_info' has no member named 'r_offset'
dyngen.c:1858: error: 'struct relocation_info' has no member named 'r_offset'
dyngen.c:1872: error: 'struct relocation_info' has no member named 'r_offset'
dyngen.c:1915:2: error: #error unsupport object format
dyngen.c:1849: warning: unused variable 'type'
make: *** [dyngen] Error 1

But there is project: http://www.kju-app.org/kju/ that manages to
compile and run (very well) qemu under MacOS X. They are using
standart XCode Developer Tools so this could mean gcc-4.0.

I would be great if someone with grater knowledge on the subject could
combine kju and neo1973 emulators to make such emulator possible. What
do you think?

Experiments

Here you may find my experiments while I was trying trying to run openmoko emulator on my Mac.

Prequisites

I followed instructions in: http://www.openembedded.org/wiki/BuildOnOSX

Get Q[kju]: http://www.kju-app.org/proj/wiki/CompilingQ into /Volumes/OE/Q but do not compile it yet (run only "prepare the sources")

Set up environment as described in MokoMakefile:


sudo port install quilt
 sudo port install py-psyco

cd /Volumes/OE
mkdir moko; cd moko
wget http://www.rwhitby.net/files/openmoko/Makefile

make setup

Patching qemu-neo1973

The main idea is to get patches for gcc-4.x from Q project and apply it to qemu-neo1973 branch. I'm still working on it.
