As I'm sure you know, OSX does support X11, so your plan will work fine once you get past the audio issues. You might check MacPorts and Fink to see what they've done about audio.

Here's where I found the indication of an OSX port: http://lists.freedesktop.org/archives/spice-devel/2010-June/000583.html

If you want to do an X11 build, then you do *not* want gtk-osx, which does a quartz build of Gtk+. As I'm sure you know, OSX does support X11, so your plan will work fine once you get past the audio issues. You might check MacPorts and Fink to see what they've done about audio. Yes, Darwin is Unix, but it's a Mach microkernel wrapped with NetBSD libraries, a very different design from Linux which is a gargantuan kernel that does everything. The main issue in your case is that sound is part of the kernel in Linux, but not in Darwin and that there is no standard sound API for Unix. I know that problem has been solved, because I've seen claims of having GStreamer working on OSX (not working particularly well, mind you, but working).

In your place I would skip Phase One. I don't think that there's any benefit to that exercise.

Re: [Gtk-osx-users] Spice modulesets

[Cliff S. <cs...@vb...>]

Good suggestions.

My plan is to get Spice Client working on OSX with as little changes as possible for Phase One. That means using Gtk and X11 as it is now in Spice Client since both of these already work on OSX. In other words, just to port it to Darwin. For this phase I would not Cocoa'ize it. I am ASSUMING since OSX is Unix (Darwin) under the covers this would not be that difficult - of course I don't know how true or not this is.

Then Phase Two would be to replace/port Gtk/X11, sound, and whatever else to work on OSX. Using OpenGL, Core Audio, etc - Cocoa'ize it.

Phase Three would be to then get Phase Two working on iOS.

To date I have most of the Spice dependent libraries at least building under Darwin. I am having more difficulty getting the alsa-lib software building on Darwin.

I have not found anyone working on a Cocoa version of Spice Client. Can you let me know who these people might be? Thanks 

What do you think?

Ah. Completely diffferent. 
You're actually trying to build Spice-gtk (http://gitorious.org/spice-gtk/spice-gtk/trees/master/gtk), right? Looks doable except for audio. OSX and Linux have quite different sound architectures, so you'll have your work cut out getting that done.

I don't think that you'll be successful getting Apple to let you put a Gtk+ app on the iTunes Store for your iPad. I saw some archived emails indicating some folks are working on a Cocoa implementation of Spice Client. That has a better chance of getting accepted (it's also likely to work better on both OSX and iOS), so perhaps you should join that effort.

Re: [Gtk-osx-users] Spice modulesets

[Cliff S. <cs...@vb...>]

Spice is remote desktop software for Linux.
It already is written to use X11 and GTK.

I am porting it to OSX and iOS
I thought that the gtk-osx project would give me a head start with Quartz but it would be better to use OpenGL regardless.

It's unclear to me why you'd want to use Gtk with Spice (you are talking about the electronic circuit simulator, right?). Why not use MacSpice[1]? It's equally unclear to me what Alsa would have to do with Spice... unless you mean a different program.

And while jhbuild can automate the build process, it doesn't do any porting work. So unless there's a CoreAudio backend to ALSA (seems unlikely), you'll either have to find a patched version of it somewhere or port it yourself -- which probably means writing a CoreAudio wrapper with the ALSA API.

[Gtk-osx-users] Spice modulesets

[Cliff S. <cs...@vb...>]

I am new to the gtk-osx project.
I thinks it is a kool concept.

I am attempting to create a moduleset for Spice. I am porting Spice to OS/X and then iOS.
I would live to build a moduleset for Spice with all its dependencies.

I have read the documentation but just have not been able to figure out how to create modulesets successfully.
So I have been building the dependent libraries by hand in the jhbuild shell.

I am stuck trying to build the dependent alsa-lib-1.0.24.1 on OS/X.

Has anyone tried Spice and/or alsa-lib with gtk-osx???

Thanks

Re: [Gtk-osx-users] Question about programs portability

[Shawn B. <sha...@ho...>]

I whole heatedly agree with John. He speaks true words of wisdom. I wish I had  (listened to) that advice 3 years ago, when I started down GTk for the expressed reason of cross compatibility. If you are starting from scratch, don't start with GTK. As a novice, I can attest to that. It is true, just cause you can do object oriented programming in C does not mean you should. In fact I would not even call it a C based interface it really isn't for all practical matter (personally I think it's worse for it). 

I don't know about other cross platform tools, but I would seriously consider the audience, and if there is no need to be cross platform, there are many advantages of going native. I have started down that path myself, trying to separate enough of the logic (in C using just libc et al, which is very portable), to have minimum interface components, that if needed, can be re-written Native to the OS interface.

You can also always do an html via web, but I never see those as serious applications. 

the whole get_object* set_object* stuff just does not work. I ended up writing a lot of bloat trying to follow the mantra only to realize having a structure with members is ultimately much easier to code than calling a bunch of get/set_Object*.

Well, on OSX you include Gtk (and all of the other libraries that your application requires) in the application bundle. MS Windows users will need to install those libraries, so for that platform you'll use an installer program. On Linux the user will have to install Gtk+ and the other dependencies via the package manager if she doesn't already have them installed. This is equally true of all cross-platform frameworks.

As I've written in the wiki, though, Gtk+ is not a good choice for new work if cross-platform portability is important to you. Although much improved over the last two years, Gtk+ remains primarily a Unix toolkit that happens (through a lot of hard work by nowhere near enough people) to compile and run on OSX and MS Windows. Qt and wxWidgets, which are designed and built with the primary goal of being cross-platform, are much better toolkits.

The problem is that gimp is firing up an event loop, which is waiting for gimp to get focus. When you launch it from the command line, the terminal keeps focus, so gimp hangs until you switch focus to it. Click in the splash screen or command-tab to select gimp and it should finish up and display its palettes and menu.

The autoregen failure was from a typo in the moduleset, fixed and pushed, thanks.

The mmx problem is because gimp's configure has code which determines that you have a 64-bit machine and ignores the -arch i386 CFLAG, so it sets up for x86_64 assembly instead of x86 assembly; gcc sensibly declines to do that. You can override configure by adding the line 

append_autogenargs("gimp", "--host=i686-darwin10.5.0 --target=i686-darwin10.5.0")

to your .jhbuildrc-custom.

I get the hang, too, so I'm building a debug version so that I can see what's hanging it up. I'll get back to you on that once I've figured out the problem.

(By the way, don't get tempted to try a 64-bit build; they're still using ige-mac-integration. I'll file a bug with them about that.)

===============================

I am not sure the reason behind it, but I fix it by exiting to shell, then do the configuration there by

./configure --prefix /Users/timchen/gtk/inst --libdir '/Users/timchen/gtk/inst/lib' --disable-python --without-x  --without-dbus --without-gnomevfs --without-wmf --enable-binreloc  --disable-static --disable-mmx
(note that the flag *--disable-mmx* is somehow needed to avoid some compile error later)

 then I exit the shell and continue the building process and gimp is finally built. 

However, when I tried to launch gimp with ~/gtk/inst/bin/gimp The splash screen appear and it hangs with the subtitle

Starting Extensions
extension-script-fu

And when I terminated the process with ctrl + c, it shows

./gimp: terminated: Interrupt
/Users/timchen/gtk/inst/lib/gimp/2.0/plug-ins/script-fu terminated: Interrupt

My first guess was that there is some sort of bug with the pygtk, but it turns out that I can run several pygtk examples without problem. 

So, I am basically stuck here. Do you think it is related to the previous error in autoreconf?

thanks,
Tim

No, the problem that that message (along with several others) addressed was that the symbol _libiconv_open is missing from the x86_64 image in Apple's distribution of libiconv. You're building i386, and the symbol _iconv_open is present in both the i386 and x86_64 images.

The new (since january) gtk-osx-build-setup.sh replaces the jhbuild stock bootstrap.modules with a replacement that builds a new libiconv regardless of architecture. I suspect what happened is that you ran jhbuild bootstrap *without* specifying the architecture to setup_sdk() and so built libiconv and gettext as x86_64, so there's no i386 image to link to. The safest thing to do at this point is to wipe everything and start over. Anything short of that will risk linkage problems in the several dependent libraries.

[Gtk-osx-users] glib version error while building gimp

[Tim C. <ht....@gm...>]

Hi, 

I am trying to build gimp on my 2011 MacBook Pro (64 bit) via jhbuild.

I basically follow the instruction on http://sourceforge.net/apps/trac/gtk-osx/wiki/Build

and I update the .jhbuildrc-custom file with 

setup_sdk(target="10.6", sdk_version="10.6", architectures=["i386"])
build_policy="updated-deps"
os.environ["ARCHFLAGS"] = "-arch x86_64 -arch i386"
moduleset = "http://github.com/jralls/gtk-osx-build/raw/master/modulesets-stable/gtk-osx.modules"

everything goes well with 

$ jhbuild bootstrap
$ jhbuild build meta-gtk-osx-bootstrap
$ jhbuild build meta-gtk-osx-core

However, when I am trying to build gimp with $ jhbuild build gimp

it complains about glib while configuring GEGL :

checking for GLIB - version >= 2.22.0... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.

Is there anything I missed?

thanks for your help,

Re: [Gtk-osx-users] GTK+: possibly undefined macro: dnl

[Chap H. <cl...@po...>]

Okay -- I encountered the same error at the same place on a new user account.

Then I created a new user on my Mac Mini (Intel) which does *not* have Xcode 4.  (It has Xcode 3.latest.)  I was able to get through the installation process there.

Unfortunately the mini is headless and I operate the GUI with screen sharing, so it's not ideal for testing GTK.  Better than nothing, though :)

If anyone has some ideas from this about how my laptop's environment might be screwed up, I'd be grateful.

Thanks,
Chap

I think the answer is, I was starting fresh.  Don't know much about "trees."

Perhaps I should create a virgin Mac OS X user and retry the process there.  My concern is, will the installation be available to all users, or just that user?

No, but you've messed something up. "dnl" introduces comments in the m4 macro language... which implies that whatever autoreconf called, it wasn't the right m4.

Yes, and instructions are in the stock .jhbuildrc-custom that was installed by gtk-osx-build-setup.sh.

Thanks for the heads-up about libtiff. But they both seem to be working at the moment, and there's no way to tell jhbuild about fallback download sites.

Hello, thanks for making tremendous GTK-OSX!

Just to report that the install is nice.
I have one small problem with access to libtiff on http://download.osgeo.org/, they gave me an other URL:
http://download2.osgeo.org/

I've also install GTK for Ada from Adacore:
http://libre.adacore.com/libre/tools/GtkAda/

It was installed perfectly.
I've just had to remove -arch x86_64 from CFLAGS because GNAT don't understand it.
I've done it by hand with Terminal. Is there some configuration file to modify?

Has nothing to do with C# in particular. There are thousands of computer languages, and dozens of independently maintained wrappers of Gtk. That's too much for a one-person-part-time project to support. Gnome officially supports C++ and Python, so that's what I support for wrappers. 

The term for your patch is "syntactic sugar". It accomplishes nothing besides saving some typing, and makes absolutely no difference for writing a wrapper... but it might make a difference for gobject-introspection, so I might do it for that.

Mono is another matter entirely. For one thing, it's not a "virtual language", it's a runtime framework (that can run several languages, of which C# is the most well known). It has it's own event loop which integrates with the OS's event loop. Gtk also has its own event loop (provided by GLib) which integrates with the OS's event loop -- and probably does so differently from the way mono does. Mixing the two is asking for trouble.

You might be able to fix your crash by getting your Mono layer to also handle either NSApplicationShouldTerminate or NSApplicationWillTerminate and do whatever cleanup it needs to do. You'll have to write some Cocoa (objective-c) code to do it, but it's not difficult. You can use the code in GtkApplicationNotify.c as a template. The hard part will be making sure that you don't have a race condition between the two event loops.

I don't think that has anything to do with Python code crashing at exit (if it does: test-integration.py doesn't, but it doesn't do much of anything, either). Python doesn't have its own event loop.

John Ralls
