Failed process 'gdk-pixbuf-query-loaders.exe' during load on Windows

[Vexatos]

Some of our Windows users are unable to launch our program after the update to Julia 1.3 and Gtk.jl 1.0.0. This appears during launch.

The line crashing is

using Gtk

Clearly, it's happening during load. Interestingly, it only happens to some Windows users, and none of our developers that use Windows are able to reproduce this issue. Since the executable shipped with gdk_pixbuf_jll appears to be the one erroring, it doesn't seem to be a problem on any other operating system.

[giordano]

This is very timely, yesterday night I faced the same issue for another package on AppVeyor. I don't know what's the problem, my best bet is that there is something weird with the PATH variable.

After installing the gdk_pixbuf_jll package (]add gdk_pixbuf_jll), could you please share the output of

using gdk_pixbuf_jll
gdk_pixbuf_query_loaders() do gdk_pixbuf_query_loaders_path
    ENV[gdk_pixbuf_jll.LIBPATH_env]
end

on both a Windows system where you get the failure and one where it works?

[Vexatos]

This is on a system where it isn't working, I'll try to get it from a working one as quickly as possible. Split into multiple lines for readability, it's a single line in the output.

We ship our own julia depot as you can see, but it also happens when using properly installed julia, we confirmed that.

[Vexatos]

Checking for the depenencies of the JLL, these artifacts all seem to be properly in the path:
cf0e...: Glib_jll
217f...: JpegTurbo_jll
4106...: libpng_jll
a42d...: Libtiff_jll

Thank you very much. I was hoping that the list was very long, but it's just 1501 characters, it should be short enough.

Still, I'm very interested in seeing the PATH on a system where it works.

Yeah, that shouldn't be a problem, on AppVeyor there is the standard setup.

[Vexatos]

This is one where it worked, in a different depot path.

Had to cut (hopefully) irrelevant paths for anonymity, it was 86 entries and just below 4000 characters in total. It's possible that the dependency dll might be in a different directory on this fairly long PATH, allowing Gtk.jl to work...

[giordano]

I was hoping there are unescaped spaces and/or parentheses only in the non-working one, but apparently also the working system has spaces and parentheses in the PATH. I think I'm running out of ideas.

[0x0ade]

Someone with a "working" environment reporting here.

I've just helped someone with a "broken" env and for them, it was caused by libwinpthread-1.dll missing, which is used by libintl-8.dll, used by libgio-2.0-0.dll and libglib-2.0-0.dll.

It cannot be found in either their artifacts dir, nor in mine. On the other hand, I've got libwinpthread-1.dll in another folder in my PATH, which just so happened to not "break" it for me in the first place.

I've shared my copy of the .dll with them and it started working fine.

Hopefully these observations will help you in any way 😅

[Vexatos]

For reference, libintl-8.dll is part of Gettext_jll which is a dependency of Glib_jll. Looks like libwinpthread-1.dll should be part of mingw.

[giordano]

@0x0ade thank you very much, that was really helpful! The library is in Sys.BINDIR, we have to add this directory to the JLL wrappers.

Thanks again for the report and the help!

[giordano]

I have opened a pull request for BinaryBuilder to address this issue: JuliaPackaging/BinaryBuilder.jl#541. Once this is merged, we'll need to rebuild gdk_pixbuf_jll, and then this should finally be fixed.

@Vexatos as a temporary fix you can add the directory where Julia is to the PATH (you can find this directory in Julia with Sys.BINDIR), check that in the same directory there should be the libwinpthread-1.dll library.

[Vexatos]

Thank you! When can we expect a new release of gdk_pixbuf_jll?

[giordano]

As soon as we fix this issue JuliaPackaging/BinaryBuilder.jl#544 that's preventing us from actually building the jll libraries 😬 Yesterday there has been a crash while we were building the new gdk_pixbuf_jll.

Did you try the workaround of manually adding Sys.BINDIR to the PATH?

[Vexatos]

I cannot test at the moment, so for now we're just dropping the missing .dll file into the path manually.
