Subversion triggers a bug in JXFS, the filesystem used on the machine I received, this FS is not usable for development. I then installed my work partition with the standard Amiga filesystem called FFS2. In order to make it faster, it is necessary to add the following line to the user-startup script (user configuration should be made there): run >NIL: fs_plugin_cache DH1:

1st May

I finally was able to copy the OOo4Kids source on the disk. Was a nightmare :

Current status : improve configure (the notepad seems to be helpful, and at least allows to modify the scripts.


Done :

Issues :


Facts:

Facts:

All settings of the OS can be changed through the appropriate "preferences" program. They can be found in the "Prefs" drawer. As an example, to set the network settings, one need to run Prefs/Internet


5th April

Back at home (uff). I tested more intensively the Amiga OS 4.1 :-)

Thoughts:

Hardware side : there are only two USB ports available. One for the keyboard, and one for the mouse. So how to add my USB key containing the softwares I downloaded? (please think 3 or 4 USB ports, 2 is not enough). 

hack : use an Apple keyboard, so, since this is an USB hub, other USB ports are available.

Facts:

The Sam440ep Flex motherboard has 5 USB ports. The only thing to know is that because of Uboot (Sam BIOS), the keyboard must be connected on the rear upper USB port to work in Uboot. After that, when the OS is loaded, the keyboard will work in any USB port.

Received my machine today !! Unfortunaly, will ony be able to test it wednesday afternoon, or even saturday.

Links for the beginning :

Thoughts:

Native extension archives on Amiga OS 4.1 is .lha Fortunately, I was able to unarchive the SDK archive, and start reading the documentation.

Strange .info files included (sort of blobs).

Facts:




Porting OOo4Kids on Amiga OS

=> Tips and tools


Milestone in progress is : 0.1


Todo (basics/first step):

Important: we really thought to a native port, and install AmiCygnix does not mean we'll use it for the port. At milestone 0.6, it is scheduled to use the native API for the controls, and the frames. Means a lot of work, something similar to the native Mac OS X port of OpenOffice.org

Cross Compilation

Everything is explained there : http://www.zerohero.se/cross/os4.html

Will give it a try though ... :-)

Result of "gcc -dumpspecs" : specs dumped by gcc


My first compilation on Amiga

simple hello

OS detection with Amiga in OOo source code

Results from config.guess

config.guess takes over the machine detection, and put the results in environment variables :

UNAME_MACHINE contains the result of `uname -m`

9.Code:test> uname -m

ppc

UNAME_RELEASE contains the result of`uname -r`

9.Code:test> uname -r

53.3

UNAME_SYSTEM contains the result of `uname -s`

9.Code:test> uname -s

AmigaOS

UNAME_VERSION contains the result of `uname -v`

9.Code:test> uname -v

3.5

(plain wrong, because should be 4.x )

Current choice

So, on the Sam440, we obtain : "${UNAME_MACHINE}:${UNAME_SYSTEM}:${UNAME_RELEASE}:${UNAME_VERSION}"=ppc:AmigaOS:53.3:3.5

A previous detection of AmigaOS is included in config.guess, so we have to add a new case. So until the 3.5 version will be fixed (for a 4.x value), we'll consider we're running Amiga OS 4.x when ppc and AmigaOS are detected (no other case does match with this result.

Conclusion => In our case, we'll display : powerpc-unknown-amigaos 


Draft

uname -a returns  :


OS=AMIGAOS // 4.x

CPU=P // PowerPC

amigagppc.mk // use unxlngppc4.mk as default values ?


Contains : 

# fichier mk Unix Linux HPPA utilisant GCC, merci de faire les modifications génériques pour Linux dans unxlng.mk

Perl stuff

Currently stalled at Perl installation step: 

checking for perl... /SDK/Local/C/perl
checking the Perl version... Can't open threads.library
checked (perl 20)
checking for required Perl modules... ./configure[6746]: Can't: not found
configure: error: Failed to find some modules

=> Perl can't run correctly (probably a configuration issue):

/AmigaOS4.1> Code:SDK/local/C/perl -v

Can't open threads.library

Update : this url might help (thanks to Chris Young for the info) : Perl pthreads.lha

TAG DONE.png I copied the one sent by Elwood, in Sys/Libs, and this solved the issue

Note: this is a hack, and should not happen in a normal installation ...


This can be achieved installing the missing modules via CPAN => Install Perl modules using CPAN

Milestones for the port (rough estimation)

-> This port will NOT use Java

Milestone 0.1

-> the version is plain wrong. must be 4.1, and 3.5 is returned

config.guess return the wrong OS. 

***Thanks to Elwood for his time, helping me to reformat the partition. 
The current new file system seems to be able to support the svn co without freeze. Crossing the fingers ...

gmake: *** [all] Error 2

Note : runargv() [unix/runargv] The runargv function manages up to MAXPROCESS process queues (_procs[i]) for parallel process execution and hands the actual commands down to the operating system. Each of the process queues handles the sequential execution of commands that belong to that process queue. Usually this means the sequential execution of the recipe lines that belong to one target. Even in non parallel builds (MAXPROCESS==1) child processes are created and handled.

Note : this part can need a lot of time (probably several month, or even a year for a basical native port).

vcl is a critical part, where :
