Hi Stefan
thanks - I've seen your message via the webfrontend earlier and thus decided to sign up. However, CCing me would have been a good idea, yes.
I am flattered, but unfortunately not skilled enough to help you. The fix I send originated from a hour-long debugging session with two other people (non-OS X developers) - I am pretty sure I would have never caught such a stack overflow by myself. (Actually, I tried debugging via gdb at first and noticed the this pointer changed when going into the newly called channelLoop function, causing the program to crash - but was more than startled because this should have never had happened. Turns out, the stack was full and the first parameter of the function, i.e., "this" could not be pushed onto it, thus reading some random memory.)
At the same time, I am happy to say that otherwise the x2go client (from git) is fully functioning on OS X with one little flaw - I have to test the same git version on Linux as well to confirm a OS X specific bug though.
Oh yeah, and building nxproxy on OS X is not trivial but easily manageable with a few build system modifications.
Best regards,
Mihai

Mihai, since you committed an OS X-specific patch: Would you be interested in picking up development of the OS X X2Go-Client? Originally, Mike wanted to take a stab at it, but didn't get around to do it, and Alex won't touch the OS X port unless he gets paid for it.
If you have the necessary skills and the time to keep the OS X port current, I could provide you with a Mac mini for testing. See http://comments.gmane.org/gmane.linux.terminal-server.x2go.devel/2112 and http://comments.gmane.org/gmane.linux.terminal-server.x2go.devel/2347 for the specs& background info.
I bought this Mac specifically so someone skilled enough can work on the X2Go-Client, and it's kind of sad that no one wants to pick up development even though hardware is provided for free/in exchange for a deposit.
I don't have enough Mac users among my clients that paying Alex (or anyone else) to work on it would be economically viable...

We are desperately searching for someone taking over the building and
testing of the Mac version of x2goclient. Not necessarily the
development.
As far as I can tell, you could be the person we are looking for. Or
rather: the beginning of a team of people.
If you could provide a set of built installer packages for a Mac
version of x2goclient, nxproxy and libxcomp (nx-libs-lite derived from
nx-libs.git) that would be awesome!!!!! NX -> idealistically without
Rosetta, but native...
Any help needed will be given to you (if we can)!!!

Hi all
Turns out, building a static, multi-arch (fat) version of x2goclient is not that easy. Not because of x2goclient, but I had to (successfully) hack openldap into building universal first. Also, my system Qt libs have no static version, so I'm currently rebuilding them.
Anyway, I should have a working version by tonight (i.e., in at most 24 hours) including a fat binary file for x86 and x86_64. ppc will take a me a little bit longer, as my ppc assembler went missing (don't ask me how exactly.) Do we even care about ppc? Snow Leopard (10.6) is not working on ppc and Lion (10.7) dropped all ppc support for good.
Btw: so far, I've been using the NX nomachine source (nxproxy, nxcomp) for building a native 2-arch version of nxproxy (with nxcomp statically linked in.) I merely had a quick glance at your nx-libs.git, but from what I could see it's just the vanilla nx source redistributed, so we should be golden.
I'll post my "installer" (really just a .dmg image with x2goclient.app in it, how all project redistribute on OS X) to the list when it's ready and I've had some sleep.
Best regards,
Mihai

Uh, I don't think posting it to the list is a good idea. I'd suggest you send it by eMail to Heinz and Alex so they can upload it somewhere on x2go.org, and if you want to, CC me, since I should have my Mac mini back from Mike in a few days and could act as a tester. (I'm not exactly experienced with Mac OS X and have a reputation for crashing Macs just by getting near to them ;-) so I should be the ideal tester - if I can get it to work, the average Joe should be able to do that, too.)

If you have web space somewhere where you upload the .dmg and I can

Maybe an xauth problem? Does X2GoClient's Qt work through X11 on Mac OS or does Qt4 connect to the graphical Mac desktop directly? Nah, Qt4 is using the native Cocoa interface on OS X. X2go then tries to start (if not already started) and to connect to the xserver on localhost:6000 (which seems weird/wrong to me, why not via the UNIX socket for instance? I guess I should try to change that.) and then it should basically work.
However, on my system the X server is listening on port 6004 instead of 6000 (thus using displayPort 5?) - for whatever reason. Due to the hardcoded connection settings in x2goclient, it won't be able to connect to the server... but again, as I was about to fix it, it started working again (probably the xserver restarted on displayport 0/port 6000), so I lost the interest and tried getting the universal build setup first.
Anyway, I'd be delighted if you could give it a try, Mike!

Oh alright, I can wait. But please do me a big favor: fetch http://www.ionic.de/x2goclient-3.99.1.0-r2.dmg - I forgot to add i386 support in the x2goclient binary before, shame on me. r2 is now featuring both x86 and x86_64 support.

Does "defaults read org.x.X11" say anything regarding the port number? If so, have you tried setting it to 6000 using the corresponding "defaults write" command (possibly requiring sudo)?

I fetched both and will give them a try once my Mac is back. ;-) Note that my Mac is x86_64-based, so I will neither be able to confirm nor to deny the functionality of the x86 support.

Nope, and note that I'm "special" yet again - I'm using the MacPorts X11-dev (that is, pretty much always the newest version.)
defaults read org.macports.X11 does give me a list with a lot of options, but only those which could be set via the GUI too (rootless, clipboard, etc.) - no displayPort or TCP port.
AFAIK the X server is autodetecting the displayPort and adding this to 6000 (i.e., port = 6000 + displayPort = 6000 if displayPort == 0).
At the same time, I really don't see any reason for connecting to the local machine via X11, I'll try to get a connection via the UNIX socket during next week. :)
I fetched both and will give them a try once my Mac is back. ;-) Note that my Mac is x86_64-based, so I will neither be able to confirm nor to deny the functionality of the x86 support. Well... personally, I don't care about x86-only machines either, as there was only one generation without x86_64 support, but since I "went the extra mile", I'd still like to know if it's working on these boxes too. Let's see if other people are reporting back. :)

AFAIK the X server is autodetecting the displayPort and adding this to 6000 (i.e., port = 6000 + displayPort = 6000 if displayPort == 0).
It might well be that localhost:0 is hardcoded in x2goclient for Mac.
Not sure, though.
Have you tried
DISPLAY=:0 x2goclient
or in your case
DISPLAY=:4 x2goclient
???
Greets, Mike

Hi Mike
Sorry for responding so late, but I didn't get around it yesterday.

Nope, that won't work on OS X. Let me elaborate.
OS X is not using X11 as all other UNIX(-like) systems do, but instead a proprietary drawing API called Cocoa (or the old, x86-only Carbon interface) based on the Quartz rendering/compositing engine.
On other UNIX(-like) systems, Cocoa/Carbon would be (for instance) Gtk/Qt and Quartz the X11 server.
In contrast to this, OS X does ship an X11 server, too, called "XQuartz", which is using the Quartz rendering engine.
Now that we covered Cocoa and Quartz, let's take a look at the Qt framework. Qt is essentially just another drawing API, providing widgets, manual drawing and whatnot. As you know, Qt can use the X11 system as rendering backend. What you may not know, is that on OS X, Qt can also use Cocoa is a backend, acting as a compatibility/portability wrapper using the Cocoa API. If using those kinds of libraries, for instance with x2goclient, your application will *not* use the X11 server at all but instead paint directly via Cocoa to Quartz.
Qt on OS X is most commonly used as this wrapper for Cocoa (because it works really well in that mode.) As such, x2goclient has also used this mode and I of course kept it this way.
This means, that whenever x2goclient is started, it's using the native Cocoa/Quartz rendering engine and we naturally can not assume that the X11 server on this machine is actually running.
Thus, the x2goclient code tries to start the X server first via a hardcoded path to startx (which sounds wrong to me, we should be using launchctl for that kind of stuff) and afterwards connecting to the hardcoded location TCP localhost:6000 (again, seems wrong, I'll try to get the current UNIX socket and connect to that instead or something like this.) Also, it should be noted that the environment variable DISPLAY it not used/handled in this code at all, so setting it is pointless (even more so for a Cocoa application. ;))
I hope I could shed some light on the internals and outline the work I have planned.
Best regards,
Mihai

Not sure how relevant this is, but X11 is removed from Mac OS X 10.8 (Mountain Lion) and has to be downloaded by the user: http://www.macrumors.com/2012/02/17/apple-removes-x11-in-os-x-mountain-lion-...

This was a really neat tutorial on graphics rendering on Mac. Thanks a
lot for taking your time to write that down.
Do you think you can improve the sitatuaion with x2goclient and send
us patches?
That would really be awesome!!! Mike

That's my plan. :) But don't expect it too soon, as I have to learn for university, too...

However, on my system the X server is listening on port 6004 instead of
6000 (thus using displayPort 5?) - for whatever reason.
Does "defaults read org.x.X11" say anything regarding the port number? If so, have you tried setting it to 6000 using the corresponding "defaults write" command (possibly requiring sudo)?
Oh alright, I can wait. But please do me a big favor: fetch
http://www.ionic.de/**x2goclient-3.99.1.0-r2.dmg<http://www.ionic.de/x2goclient-3.99.1.0-r2.dmg>- I forgot to add i386 support in the x2goclient binary before, shame on me. r2 is now featuring both x86 and x86_64 support.
I fetched both and will give them a try once my Mac is back. ;-) Note that my Mac is x86_64-based, so I will neither be able to confirm nor to deny the functionality of the x86 support.

Hi Mihai,

Turns out, building a static, multi-arch (fat) version of x2goclient is not that easy. Not because of x2goclient, but I had to (successfully) hack openldap into building universal first. Also, my system Qt libs have no static version, so I'm currently rebuilding them.
Ok! Great!
Anyway, I should have a working version by tonight (i.e., in at most 24 hours) including a fat binary file for x86 and x86_64. ppc will take a me a little bit longer, as my ppc assembler went missing (don't ask me how exactly.) Do we even care about ppc? Snow Leopard (10.6) is not working on ppc and Lion (10.7) dropped all ppc support for good.
PPC is not so interesting to us, I guess. x86 and x86_64 should get
the main focus.
Btw: so far, I've been using the NX nomachine source (nxproxy, nxcomp) for building a native 2-arch version of nxproxy (with nxcomp statically linked in.)
That would be sufficient for our first test loops.
I merely had a quick glance at your nx-libs.git, but from what I could see it's just the vanilla nx source redistributed, so we should be golden.
The source tree is pretty much vanilla NX, but the patch list is long
and those patches only get applied on (a) building the packages for
Debian/Ubuntu or (b) when I roll the tarballs you find under this URL:
http://code.x2go.org/releases/source/nx-libs/
It's such a gift that you give your time to this!!!
Thanks, Mike
