Re: [Gimp-developer] Windows builds using MSYS2

2016-05-10 Thread Petteri Soininen 

Got python working now.
Mainly four reasons why I fumbled with it for so long..
1) I had 32Bit gimp.pyd on my path for some reason. I have tried 
building both so I

must have moved it to test something and that 32/64 conflict confused me.
2) No libpython27.dll or pythonw.exe. With MSys2 there comes 
libpython2.7.dll and

python2w.exe though..
3) lib/gimp/2.0/interpreters/pygimp.intrep gets messed every time when 
building.

(this is definitely a bug in build process)
4) I once removed everything and used a different --prefix but the 
earlier installation
path in Edit/Preferences/Folders/Interpreters stayed the same even 
though other

paths changed to reflect the new location and I didn't notice it at first.
(someone might want to look at that if it's a bug)

Hopefully that helps.

Hi,

I've also been working on building Gimp for Windows simply because for
one reason or another I have Windows on my main, faster machine, and I've

https://bugzilla.gnome.org/show_bug.cgi?id=757717

I tried the Linux cross compile using the wiki Mingw64 instructions. I
was trying to retrieve the prebuilt library RPM's from, I think it's
OpenSUSE, but that seems to be outdated. Now I have Code::Blocks setup to
cross compile with MinGW-w64, I’ll try building those dependencies.

I'm investigating MSYS2. It looks like a good project and a lot of other
projects seem to use it to provide releases for Windows, but its a slow to
compile even with multiple threads set.  Some of those projects may use
Python so they might be able to help with Python for Gimp.

I attach my current "autogen" and "make" outputs. I am building with most
extras disabled as I just want to iron out the build process first.

Are you building from the main branch ?

Do you get a successful build with Python disabled ?

Cheers.

The fact is that there are no reccurent Windows developer in the team.
Like even though we may have patches from time to time, nobody from
the Windows world seems to be here to stay. For myself, I am one of
the rare one who will do sometimes a patch for GIMP on Windows (and
really out of sympathy since I myself don't use Windows and haven't
really for years and years!). But when I do, I cross-build GIMP on
Linux and test it in a Windows VM. I don't build it on Windows
directly.

So it does not surprise me that the instructions to build GIMP on
Windows are quite bad. Few people ever do this and I'm not sure when
this may have been last updated.
If you have fixes to do to the howto, you are welcome to propose them,
and we could update the wiki. If you manage to do this, you will
probably know more on the topic than most of us. Also if you are a
Windows developer, you would be more than welcome to contribute
patches and improve GIMP on Windows. I would propose that you come and
hang out on IRC, and that you check out the bugtracker to propose
patches. :-)
Thanks!

Jehan
