Unslung/WL500g packages available for Oleg's firmware

[oleo]

mtpsync uses gtk and that means that you must run X on router. But xlibraries were not fully ported to uclibc. There are provisions for command line in mtpsync, but sources neeed to be patched to exclude gtk part. This is hard to do as command line is merely convenience feature.
So, no mptsync.

mtpfs uses FUSE userspace filesystem than needs to be included in kernel This could be done by creating custom Oleg firmware as in http://trac.nslu2-linux.org/optware/...rmware-oleg.mk
Kernel 2.4 needs to be patched. Another obstacle, but can be done.

gnomad is another gtk application. no go.

MTPdude also requires gtk. Sorry.

[gdraanen]

Countless references through mtpdude, gnomad2, forums, recompile-threads... others, I ended up at libgphoto2

Interest in mtpdude and libmtp versions seems to have dried-out in favour of this libgphoto2 project.
It has a bit of a misleading name, because the project does a lot more than enable connection of camera's. They also support most-any MTP device.
And the Creative Zen Vision:M is specifically mentioned as 'supported' !!

See ( http://www.gphoto.org/news/ ) or its download pages ( http://sourceforge.net/project/showf...?group_id=8874 )

libgphoto2 is the library,
gphoto2 is the command-line interface to it, and
gphotofs seemingly allows to mount a camera (or mediaplayer)

So... can someone cross-compile these to the wl500g 'unslung' --or wherever precisely-- that would allow it to be used via the ipkg ?

And sorry for requesting libmtp first. It seems a lot of people have been struggling with the applications built on top of that (like mtpdude's versions and the sudden-stop on development efforts in that area)

libgphoto2 (v2.3.1, dec'06) :
http://sourceforge.net/project/showf...ackage_id=8957

gphoto2 (v 2.3.1, dec'06) :
http://sourceforge.net/project/showf...ckage_id=66654

gphotofs (v 0.3, sep'06) :

Or, from second source ? ... the various versions in ftp:
http://ftp3.ie.freebsd.org/pub/sourceforge/g/gp/gphoto/

==
The bad news is that I saw gphoto2 and libgphoto2 in the 'broken packages' in http://trac.nslu2-linux.org/optware/...ages-wl500g.mk
===

How would I know which 'version' is the 'broken' one listed for wl500g ?
Who is able to spend some time on figuring this out ?

I am not a developer, don't have a linux machine (apart from the mini-mini wl-hdd that's running on Oleg's firmware at 125MHz ), and really wouldn't know how to get these packages bundled for the ipkg system. My last experience with build, compile etcetera is from more then 15yrs ago...(making OS/2 EE).

Gerard

[oleo]

GTK library depends on X libraries. They ar broken an all dependent packages.
wl500g package feed os not supported any more. I use oleg package feed.

There are the following obstacles that prevent you:

1. X, GTK and dependent packages are not upgraded to uclibc
2. wl-hdd has only 16MB ant htus running X applications is hard on it
3. You need X display for running X programs. This normally means running Linux and Xorg. There are some free X display emulators for Windows, byt support for them is minimal.
4. Porting X and dependent packages requres at least 3 days of hard work.

The best way for you is to find console application, if exists. Then I can spend some time to port this. Meanwhile read this explanation: http://www.nslu2-linux.org/wiki/FAQ/Optware-uClibcBuild

[gdraanen]

The mentioned libgphoto2, gphoto2 and ghpotofs should not have a dependency to X or GTK.
gphoto2 uses a CLI.

gtkam DOES have a GUI, but is not needed to get MTP -media- devices to connect to the WL-HDD.

You state that the wl500g is not active ? using the 'oleg' builds instead ?
But then.... I will probably have to change something in my
ipkg update, because that one uses the listing provided for the wl500g ?

Gerard.

[gdraanen]

From the link you gave, I understand there's a "better" uclibc, allowing code to be less platform dependent.

Am I to understand that I should be transferring the 'source' of my ipkg available packages from wl500g to 'oleg' ?
The link shows some details:

===========
# get the better ipkg
wget http://ipkg.nslu2-linux.org/feeds/op...3-9_mipsel.ipk
#install it (ignore tne missing lists/wl500g error)
ipkg.sh install ipkg-opt_0.99.163-9_mipsel.ipk

# get the better uclibc
wget http://ipkg.nslu2-linux.org/feeds/op...-12_mipsel.ipk
# install it (ignore tne missing lists/wl500g error)
ipkg.sh install uclibc-opt_0.9.28-12_mipsel.ipk

# update the list using the improved ipkg
ipkg update
===============

Is this what I should be doing ?

I understand also, that you did already cross-compile the libmtp which has now become obsolete with the availability of libgphoto2.
While you spend some time on the gphoto2 stuff, I would then at least be able to do some initial testing through the libmtp.
Once you have an oleg build, I can then transfer to the libgphoto2 and gphoto2 parts.

Correct ??

[gdraanen]

Conform the instructions on
http://www.nslu2-linux.org/wiki/FAQ/Optware-uClibcBuild
I updated from the 'wl500g' to the 'oleg' feed.

I seem to have been able to re-install / update my installed packages from the new 'package' source:

I did see some 'complaining' message from vsftpd / xinetd pass, so I re-checked their .conf files. Also, some packages were complaining on non-availability of md5.sum but that seems to have no visible effect.

Next i did a flashfs save/commit and a system reboot.

Then, after ipkg install libmtp,
Creative Zen Vision:M is listed in /proc/devices , but still Driver=(none)
A $cat drivers lists: usbdevfs, hub, usblp, audio, usb-storage .... but sadly nothing specific to the Zen yet.

....... but I can feel I'm getting closer to getting this media-device connection item resolved ....
With a little more help from oleo ... or one of the other viewers.

[oleo]

Ask LIBGPHOTO2_MAINTAINER=Marcel Nijenhof <nslu2@pion.xs4all.nl> to fix
uClibc port for lib and dependent packages. If not, I can try.

[gdraanen]

Oleo,
You noted that the packages may need some attention to ensure that all dependencies are met.
I've mailed the maintainer (Marcel ...) with your request, and some of my further information.

Hopefully he is in a position to spend some time on this.

Let's give it a few days at least.
.....but later I'll start nagging you again

Gerard

[oleo]

OK. I've had some problems with linking libgphoto2.

[oleo]

With upgrade to latest version and som hunk align in http://trac.nslu2-linux.org/optware/changeset/5790 ligphoto2 and gphoto2 now builds with uClibc.

[gdraanen]

Oleo, thanks very much for getting this cross-compile done !!
The maintainer of gphoto2 also responded via e-mail, so I can now take-up a few matters on completion with him.

Currently: ipkg libgphoto2 and gphoto2 --> success
gphoto2 sees, recognized the device --> Mij Zen is connected !!

In a 'summary' it reports a number of capabilities from the Zen correctly, like size of harddisk etc. (it is however reported as RAM ?!)
It seems that the gphoto2 people have still some work to do on properly supporting the file-structure in the zen. The directory info currently has a lot of '???????????' characters in it, and doesn't quite look good .... YET !

Anyway....
Thanks again for the cross-compile. You might also want to look into FUSE allowing gphotofs to be packaged.

I'll report back here when I have some 'real' progress to report.
Gerard.

[gdraanen]

Oleo,

I noticed that nslu2 already has the cross-compile for fuse in
http://ipkg.nslu2-linux.org/feeds/op...ts/ixp4xx-2.6/
(fuse-utils_xxxxxx)

Does this mean that 'transporting' this to the
http://ipkg.nslu2-linux.org/feeds/op.../cross/stable/
becomes easier ?
IF it would be there, would that indicate that I could download it and get it installed as an ipkg? or are there extra steps ?

Have any of the developers from gphoto2 / libmtp contacted you ?

I'm just hoping to see some progress here, while http://sourceforge.net/sendmessage.php?touser=48092 (MarcusMessner) is working on my bug report at http://sourceforge.net/tracker/index...74&atid=108874

Steps seem to be
1) verify that libmtp / mtpfs has now become a subset of libgphoto2 / gphotofs (it seems so, because gphoto2 also supports playlists..)
2) get libgphoto2 /gphoto2 to properly display the details of my Creative Zen
3) get someone to 'allow' FUSE (fuse-utils_xxxxxx cross-compile)
4) get someone to cross-compile either mtpfs or gphotofs

And sadly, this is not something that I can directly help with.

[oleo]

Fuse is integral part of kernel. This means that there should be some code that produce fuse module for kernel. I have included kernel as whole package called firmware-oleg. I can add some patches to kernel to support fuse. There is no way for transporting ixp fuse. Just Ideas maybe.

But really you should send requests for kernel upgrades to Oleg, not to me. If he wil not respond to your requests there are other options also. For example OpenWRT and X-wrt firmware already includes fuse module. And optware also runs on them. So we could prepare mtpfs for ddwrt feed only.

Nobody contacted me on this matter.

[Oleg]

Does it (module) requires kernel patching or could be build outside kernel tree?

Also, I need an url to this module sources.
