[Gimp-developer] Nightly Build of GIMP

[Jehan Pagès <jehan marmottard gmail com>]

Hello people!

Who takes care of the Nightly dev builds of GIMP here:
http://nightly.darkrefraction.com/gimp/ ?

I see we link this page on the official download page, so I guess
that's someone from the team.
I'd like to know what versions of libpng and cairo are used for these
builds. Are these binaries taken from another project or self-built?
Which exact version? With which build options?

A user reported consistent crashes on Windows 7 32-bit, both for the
master and gimp-2-8 nightbuilds, on simple resize/move events (Bug
707653 ). On Windows 7 64-bit running these 32-bit binaries, I could
reproduce very bad drawing bugs with the same binaries (no crash, but
the user crash happens on expose events in his traces, so I think
that's the same problem).

But I could not reproduce this with my own Windows builds, both for
master and gimp-2-8. After some tests, I see that the problem comes
from cairo and/or libpng (basically I can take my own libpng15-15.dll
and copy over libcairo-2.dll to the nightbuild prefix, and it would
work).

But I could not reproduce by recompiling myself libpng-1.6.3 and
cairo-1.12.14. So I am wondering if the problem does not simply come
from somehow broken dll in the nightbuilds. Thus I'd like to know how
these have been build, which version, etc.
Thanks.
