Taki: Compiling QEMU with SUSE 10.2

under Debian Sid. I have to change slightly openmoko/env and openmoko/download.sh to make it run on Linux:
* in openmoko/env s/make=gmake/make=make/
* in openmoko/download.sh changed line 34 to: files=`lynx -dump $download_dir | grep http | sed "s,[0-9 \t\.]*$download_dir$[a-zA-Z0-9_\.-]$[ \t]*,\1,"`

Thanks, hopefully should be fixed. make was changed to gmake in the first place to account for BSD.[[User:Balrog|balrog]] 23:11, 5 April 2007 (CEST)

== Gentoo, AMD64 ==

Where can I report bugs in QEMU-Neo1973? It fails to compile:
/server/projects/openmoko/qemu-neo1973/target-arm/op.c: In function 'op_iwmmxt_movq_wRn_M0':
/server/projects/openmoko/qemu-neo1973/target-arm/op.c:1374: error: unable to find a register to spill in class 'GENERAL_REGS'

:I assume you're using gcc4 (gcc-config -l). Qemu fails to build if you use gcc4 as it only builds with gcc3 at this time. More information:

How to do a downgrade to gcc3 just for Qemu: http://forums.gentoo.org/viewtopic-t-537643-highlight-qemu.html - be aware, though, that the kernel modules may not load if you built the kernel with gcc4, so a kernel recompilation may be in order also. [[User:Abraxa|Abraxa]] 19:38, 7 April 2007 (CEST)

I encountered the same problem, but I still had a gcc3 installed (gcc-3.4.6-r1 in a seperate slot from the system default gcc4, to be exact. This means that if you're using gentoo, you will '''not''' need to downgrade your system gcc). I simply added --cc=gcc-3.4.6 to ./configure's switches and make finished without major problems. --[[User:LordHelmchen|LordHelmchen]] 20:12, 11 April 2007 (CEST)

If you still encounter this problem with gcc3, make sure you don't have -march set anywhere like in CFLAGS (I had -march=athlon-xp). unsetting CFLAGS before re-running the configure script solved the problem for me. --[[User:Vegar|Vegar]] 22:10, 24 April 2007 (CEST)

== Basic question ==

I am using the emulator after compiling 'make qemu'.
The basic gui screen has been created and it asks the following:

'Touch the crosshairs to calibrate the screen'

Unfortunately I do not know how to continue from this stage on...
Any mouse click on the crosshairs, or a keyboard touch won't initiate a click...

Does any body know how can I click the emulator screen and continue from this stage? --[[User:nighthawk|nighthawk]] 01:12, 9 April 2007

I use mouse click and it works --[[User:Filippo|Filippo]] 22:16, 8 April 2007 (CEST)

I find a single click will not register. Which makes sense if you think about a fingerpress on the screen. I hold down the mouse and wiggle it a bit to get the buttons to register. -- DonPark 8Apr07

Still got problem with enabling the mouse. I tried according to the QEMU guide to see which mice are available under what I used. (ALT-CTRL-2, command 'mice info') and there was only the following:
* Mouse #0: QEMU S3C2410-driven Touchscreen

Does anybody got the same problem as I got?

== FreeBSD and last qemu... ==

1. Comment lines 49 and 50 in file gnokiigsm/device.h

<pre>
//size_t device_read(__ptr_t buf, size_t nbytes, struct gn_statemachine *state);
//size_t device_write(const __ptr_t buf, size_t n, struct gn_statemachine *state);
</pre>

2. Compile all with gmake

3. '''ONLY''' for FreeBSD users (as root):

<pre>
#kldload aio
</pre>

4. Have fun :)

== flash.sh fails ==

looks like I'm somehow getting a variable confused... when I try to run flash.sh with no arguments, I get a bunch of errors from sleep telling me that items such as `nand' for instance is an invalid time. I've encountered this problem both from the makefile and from a manual download. From what I can deduce, $2 should contain the number of (micro?)seconds for sleep to wait, but it looks like there's a target list, or some series of commands that are getting crosswired in.

If it helps, I'm running ubuntu fiesty X64

any help would be appreciated

Thank you,

== Compiling QEMU with SUSE 10.2 ==

* Install gcc version 3.3.6. It can be downloaded from [http://gcc.cybermirror.org/releases/gcc-3.3.6/gcc-core-3.3.6.tar.gz http://gcc.cybermirror.org/releases/gcc-3.3.6/gcc-core-3.3.6.tar.gz], for example. After unpacking it somewhere do

cd gcc-3.3.6/
./configure --prefix=/home/archive/moko/gcc33 --program-suffix=-3.3
make bootstrap
make install

Please '''replace''' /home/archive/moko/gcc33 with a path of your choice, since it will be the one where gcc33 will be installed.

* Add the following line in file openmoko/trunk/src/host/qemu-neo1973/usb-linux.c to get it compiled:

#include <sys/ioctl.h>
#include <linux/compiler.h> <-- ADD THIS!
#include <linux/usbdevice_fs.h>

(Hint found at [http://osdir.com/ml/emulators.kvm.devel/2007-01/msg00101.html http://osdir.com/ml/emulators.kvm.devel/2007-01/msg00101.html])

The next steps depend on what method you use to compile stuff:

* If you are using [[MokoMakefile]], as I do, edit Makefile around line 266 to involve gcc33:

$${OMDIR}/openmoko/trunk/src/host/qemu-neo1973/configure \
--target-list=arm-softmmu \
--cc=/home/archive/moko/gcc33/bin/gcc-3.3)
[ -e build/qemu/openmoko ] || \
* Manually on the command line:
./configure --target-list=arm-softmmu --cc=/home/archive/moko/gcc33/bin/gcc-3.3
make

Please remember to use the path you chose above for gcc33!

* Finally run
make qemu
Enjoy!
