回覆: Outdated win32 bundle


As Nacho mentioned in his earlier email on this topic free days ago, there is a bug in the introspection part that is working on getting introspection to work better on Windows, 728313, which I checked lady week the patches there still applies to the latest git master, which is still pending further review, and it should make introspection more portable, by using items from python itself(namely, distutils)

I am also working on a master solution file which contains various msvc projects that will build the dependencies of the GTK+ and GTK+ itself (2.x and 3.x).  This is still wip, at github.com/fanc999/gtk-msvc-projects, and I will let people know when it's ready for use.

With blessings.

主旨: Re: Outdated win32 bundle


sorry to use Daniel's email, but since this thread keeps growing, I'm
just using the latest entry point to try and give some actionable

It's all well and good that everybody has their own builds, and
packages, and installers — and I mean it: it's great to see so much
activity around GTK on Windows. Now, if only that translated to more
contributions to the backend code… *wink* *wink* *nudge* *nudge* ;-)

While people doing their own builds is great, I'm still going to ask
for one thing: please, help out setting up an automated builder that
takes the GTK git repository and builds it with the Windows backend.
Running the test suite would even be amazing, but I'd settle for
verifying that commits do not break the Windows backend.

Seriously: if you are an app developer that already has a build
environment for GTK, then you're already set. You don't have to change
anything in your workflow — though you'll be advantaged by a
continuous integration system that at least verifies that each release
of GTK builds on Windows (and possibly does not regress, any more that
it may regress on Linux).

The GTK team does not, currently, have the capacity to set up this CI
system. Nor it has the capacity for building binary distributions of
the libraries for Windows. That's why my strong suggestion, after
speaking with the people that are *actually* working on the Windows
backend — namely Ignacio and LRN — is to concentrate efforts in the
infrastructure to verify that the Windows backend does not break with
every release, or every commit. Application developers relying on a
binary distribution coming from gtk.org in the past have different
options for getting a replacement — they have been listed in this
thread. If you want to help the GTK in improving the Windows support
then you can:

* work on the infrastructure, in a way that can be automated and
maintained even if you happen to leave the project
* work on the Windows backend itself, by triaging old and new bugs;
fixing them; catching regressions during the development cycle; or
implementing new features
* work on improving jhbuild use on Windows
* work on improving introspection on Windows

These options are not mutually exclusive; they are *all* important.

So, let's try and get to something actionable. Can somebody try and
set up a CI for GTK that either cross-compiles GTK or compiles it
natively? Both aspects are important — as Daniel pointed out,
cross-compiling the introspection data is currently not possible, so
that leaves out dynamic languages like Python, _javascript_, and Perl;
plus, it does not allow us to run the test suite. Cross-compilation is
fine for an auto-builder that verifies that commits are not breaking
the build on Windows, which is a good start.

Another actionable point: helping out triaging the Windows-related
bugs on Bugzilla. What's still relevant? What's obsolete? If there are
patches, are those still applicable, or can they be rebased? Does a
bug filed against GTK 2.x still affect GTK 3.x?

Is anybody willing to help out Ignacio and LRN with the missing
functionality of the Windows backend?

What about jhbuild? Can somebody set it up on Windows and file bugs
whenever something breaks?
