Fair warning: ImageView will switch to Gtk about imageview.jl

[cbecker]

Sounds great ;)

For the tests, Gtk doesn't seem to come prepared with tests, because I get

julia> Pkg.test("Gtk")
INFO: No packages to install, update or remove
ERROR: Gtk did not provide a test/runtests.jl file
 in error at error.jl:21
 in test at pkg/entry.jl:711
 in anonymous at pkg/dir.jl:28
 in cd at ./file.jl:20
 in cd at pkg/dir.jl:28
 in test at pkg.jl:67

Though I tried include("/home/<USERNAME>/.julia/v0.3/Gtk/test/tests.jl") and worked fine.
I am running julia v0.3.1 on archlinux 64-bit.

[juliohm]

Very good news! I added the package here without problems.

[elsuizo]

great Tim¡¡ on a fresh install in Debian sid works fine

[rsrock]

Works here too. One hiccup that I encountered is documented here: JuliaPackaging/Homebrew.jl#69

[timholy]

This is great news.

Another fun thing to try while you're waiting (and it could easily be a couple weeks before I get to this): for those of you who build your own Julia, you can precompile it with Gtk. That means basically no delay for graphical applications. You'll only have to wait for ImageView itself to load, but it's not a huge package.

[daniel-perry]

I was able to install it fine in ubuntu, no problems
Using both julia v0.3.0 and the a recent v0.4
6b3276fdb528c6ac05f8fcd826bef0cee1f362b2.

I opened a ticket for Gtk.jl about the tests.jl vs runtests.jl file.. in
case it just needs to be renamed? It'd be more convenient to just run
Pkg.test("Gtk"). - JuliaGraphics/Gtk.jl#120 .

In mac os (10.9.4), I can build and test fine (using macports gtk) with the
same v0.4 julia above.

(I ran into a few problems running the tests in v0.3.0 julia on mac os, but
the errors didn't seem specific to gtk, so I'm going to take a closer look
when I get a chance and open a ticket if needed... especially since others
don't seem to have problems on mac os...)

Great, thanks especially for the Gtk ticket.

On the Mac, did you install via Pkg.add("Gtk") or did you have to/choose to intervene manually?

[daniel-perry]

For mac it needed a little fiddling...

I tried Pkg.add("Gtk"), and it attempted to use the Homebrew.jl package to
install gtk, but that didn't work.

So I unlinked my system homebrew gtk as suggested here
JuliaPackaging/Homebrew.jl#69
JuliaPackaging/Homebrew.jl#69, and that worked for
v0.4, but still had problems with v0.3...

So then I noticed on the Gtk.jl readme it suggested using Macports (added
macport binary directory to loadpath)... I switched to that which again
worked for v0.4 but still having problems with v0.3.

Again, not sure if v0.3 is gtk specific or not... once I get some more time
to mess with this, I'll take another look..

When you run into problems, the output of BinDeps.debug("Gtk") is useful
for us.

Here is what my v0.3 is currently saying when I include the tests file:

[timholy]

This is probably not relevant, but just to check: have you recently done a Pkg.update? Cairo made some changes recently that affected Tk, although I suspect that's different from what you're seeing. But wanted to mention it in case it's an easy fix.

[staticfloat]

You have multiple different Gtk installations sitting side by side. Choose to go with either MacPorts, System Homebrew, or Homebrew.jl, and remove the other two. Then run BinDeps.debug() again.

[daniel-perry]

So... is there a way to only use the System homebrew ? I tried uninstalling Homebrew.jl ( Pkg.rm("Homebrew") ), but now everything is complaining that Homebrew.jl is missing:

julia> Pkg.build("Cairo")

[staticfloat]

You shouldn't uninstall Homebrew.jl; even if you don't use it to provide your binary dependencies, it still needs to be around. If you have a functional set of Gtk libraries in your system homebrew, they should be used instead of the Homebrew.jl ones by default, so don't worry about that.

For now, I would Pkg.add("Homebrew") again, then just Pkg.build() followed by BinDeps.debug() if things don't work. Please post all logs and errors in their entirety. System Homebrew libraries will be represented as SystemPaths in BinDeps.debug() that start with /usr/local/Cellar.

[daniel-perry]

Ok... I re-instlalled Homebrew.jl, but removed all the packages to be sure only the system-brew-installed dependencies would be found (my system had . But when I re-build Cairo it re-installs all the same dependencies using Homebrew.jl (see below)...

I assumed it would detect the system libs and not install the Hombrew.jl version, but that doesn't seem to be the case?

(I can just use the Homebrew.jl versions if that's what should be done... But if there is some way to use system libs instead that's preferable because it seems painful to have to unlink all my system homebrew libs whenever I re-build a julia pkg.)

Thanks for your help.

Very helpful, thanks. Try running brew link --force gettext, remove the
homebrew.jl packages and try again.

Ok... I re-instlalled Homebrew.jl, but removed all the packages to be sure

But when I re-build Cairo it re-installs all the same dependencies using
Homebrew.jl (see below)...

I assumed it would detect the system libs and not install the Hombrew.jl
version, but that doesn't seem to be the case?

(I can just use the Homebrew.jl versions if that's what should be done...
But if there is some way to use system libs instead that's preferable
because it seems painful to have to unlink all my system homebrew libs
whenever I re-build a julia pkg.)

Thanks for your help.

That seems to have worked... so it has to have all dependencies satisfied or else it installs them all via Homebrew.jl? Good to know.

I will try the same now with Gtk and let you know how it goes.

[daniel-perry]

Yep Gtk built fine and now passes the tests (mostly)...

I do get a "dynamic session lookup failed" message the first time I run the test, but the second time it seems doesn't .. I thought maybe it was because X11 wasn't running when I ran the tests (it launches it eventually), but even if I start X11 and then run the test, it still has that message the first run.

And then if I quit X11 julia crashes..

Should either of those items go into a ticket?

All of the dependencies must come from the same source or the system linker gets very confused. I alternate between nuking Homebrew.jl/deps/usr putting /opt/local or /opt/brew in my DL_LOAD_PATH to test various configs, all the way back to Julia 0.2 -- then rerun Pkg.build("Gtk") to fixup all of the deps files in the dependency tree (eg Cairo.jl and Gtk.jl). If you install Homebrew to /usr/local, than you either need to use it exclusively, or uninstall it between tests of different configurations.

[daniel-perry]

Thanks for the explanation. Makes sense that they all need to come from the same source, now that you point that out. Installing homebrew to /opt/brew and using DL_LOAD_PATH is a good idea.. that will make it easier to switch between them.

[rsrock]

Jameson, I seem to remember seeing that you don't like how Homebrew dumps everything into /usr/local. Is /opt/brew working better for you in general? The Homebrew folks go to great lengths to encourage everyone to use /usr/local, I know.

Just asking because I'll probably nuke my Homebrew when Yosemite comes out. May as well set it up right...

[staticfloat]

Just so you know, if you install things into /opt/brew, you won't be able to use the majority of prepackaged binaries (bottles) with Homebrew; things will still work, but your machine will have to compile a lot of stuff. I personally use Homebrew in /usr/local on about half of my machines, and it works pretty well for me as long as I use Homebrew for most softwares. I install the software that is not available from Homebrew into ~/local and adjust my paths accordingly, but if you want to do it the other way around, (put manually-installed stuff into /usr/local and put Homebrew into some other location) it should work as well.

putting brew somewhere else lets you choose not to use sometimes (either /opt/brew, or ~/local are reasonable choices). /usr/local works well in most cases, because people are content to stay within the Homebrew world, or build from source while linking against Homebrew.

technically, brew isn't even in /usr/local by default, just optional symlinks – all of the real content is in the Cellar. this is strongly reminiscent of Frameworks (where the real content is in /Library/Framework quite often, and just symlinked to /usr/lib). the advantage here is that is possible to link against some library that is not the default (esp. with respect to having multiple versions installed), and let the linker figure out which library you actually wanted at runtime (via two-level dlsym resolution). this works very well if you can do all of the linking at once, since you can guarantee that the library versions won't change on you across machines, upgrades, installation of new libs in /usr/local/lib (which would normally end up higher on the lookup path), and so on. In Julia's case, however, each library is independent. Someone needs to make sure that if I make calls to GLib through Cairo, it is calling the same GLib that I called directly – otherwise unpredictable things happen (on the other-hand, if I need libz and you need libz, it doesn't matter if we use a different libz, as long as we don't try to take global state created in one copy and hand it to the other copy of libz). This step is where the package managers diverge significantly in their approach:

1. Darwin versions libraries into a specific folder structure so that you should only end up with exactly one copy, plus has private, relocatable Framework folders to give individual applications control of their libraries
2. Homebrew prohibits duplicating system software libraries (with an exception for cellar-only libraries that can be explicitly requested)
3. Homebrew.jl inherits the general strategy from Homebrew, but defaults to being a private relocatable copy
4. MacPorts prohibits linking to system libraries and requires that everything be self-contained and self-consistent within the MacPorts folder

Each approach has it's own advantages and disadvantages. Darwin's approach works well as a system approach, since applications can depend on a unchanging view of the world, and plugins for those applications can depend on the application providing a constant view of the world (consistency by process ordering). MacPorts approach works well if you are willing to trade increased space and install time requirements for full isolation (consistency by design). Homebrew's approach works well if you are willing to track and manage potential interactions yourself (consistency by user awareness / intervention). Homebrew.jl's approach works well, except sometimes it might get confused by software in /usr/local (I'm not sure whether to call this consistency by user inaction, or consistency by design). hopefully that was helpful, and not just a massive wall of text.

@staticfloat yes, quartz is enabled: https://github.com/staticfloat/homebrew-juliadeps/blob/73c6cfe04e54883d606cdd3f0203fc6094b66020/gtk%2B3.rb#L39

If I quit X11 while julia is still running, julia crashes:

this is a little like complaining either "I shutdown my computer and my programs stopped running" or "I quit the program and my program stopped running". it just isn't possible to keep running at that point.

If gdk tried to keep running, it would likely just segfault very shortly afterwards, since all of the user interface pointers are suddenly and unexpectedly invalid. see gdk_x_io_error if you're interested in where it gets killed. We could replace the XLib fatal error handler (XSetIOErrorHandler) with our own, but we can't do much more than die quickly, before someone tries to make a call into gtk – which is exactly what the existing error handler does.

[staticfloat]

I knew I had enabled building of it, but I wasn't sure if we were using the quartz backend. And Jameson's summary above is spot-on regarding package managers. :)

[vtjnash]

on the next line, you also disabled X11 (https://github.com/staticfloat/homebrew-juliadeps/blob/73c6cfe04e54883d606cdd3f0203fc6094b66020/gtk%2B3.rb#L40) so it's the only backend that could be used :)

of the 4 approaches described above, only Homebrew seems wrong to me, since it requires user awareness to keep it working – and in the event the user forgets it can cause any of the other 3 to break, whereas the other 3 approaches maintain an element of isolation. of course, Darwin's approach could break everything too if the OS changed, but being dependent upon the OS to maintain a consistent view of the world seems like a necessary and acceptable risk. I split them into 4 categories, but they could probably be reduced to 2: Darwin/Homebrew and MacPorts/Homebrew.jl

@vtjnash and @staticfloat, that was very helpful-- thanks! Also good to know about BinDeps.debug().

Right.. duh... makes sense... by loading the Gtk library I've created a
dependency on X11 so killing that is going to create problems... probably
should have thought that through a little more before reporting it...
thanks.

@daniel-perry, I reported the same problem with "Dynamic session lookup supported but failed"
in JuliaGraphics/Gtk.jl#121. After brew update,
$ cp /opt/brew/Cellar/d-bus/1.8.8/org.freedesktop.dbus-session.plist ~/Library/LaunchAgents/
$ launchctl load -w ~/Library/LaunchAgents/org.freedesktop.dbus-session.plist

[lucasb-eyer]

When this happens, we should also try to play nice with GtkInteract.jl.

[timholy]

I totally agree. Or at least base it on Reactive.jl, if GtkInteract doesn't allow (and shouldn't change to permit) the amount of customized layout we will need.

In my own custom GUIs, I'm just now starting to use Reactive for all the entry widgets, etc, and it's a joy to be able to just push! a new value from the REPL to update the state of the GUI. (CC @shashi 😄).

[shashi]

Yay! :D

[timholy]

This is done.
