Hello,
The recent libpng update to 1.6 has broken building every package
indirectly depending on it: the .pc files referenced the 1.5 version,
which has now disappeared.
sorry if I did something wrong. I tried my best upgrading libpng and
asked for confirmation in the receipe changes.
what are these .pc files? perhaps package-config? Are they part of libpng?
Should I change something in libpng? I have seen that a new, minor 1.6
release is out so I planned an update anyway, although it is minor and
not a security concern like this update was.
I already can't rebuild ImageMagick, because librsvg's .pc complains. I
can't rebuilt librsvg, because gdk_pixbuf's .pc complains.
Note that because of the way those .pc are used in the configure
scripts, the errors happen during building, and look unrelated, eg:
rsvg.h:31:25: fatal error: glib-object.h: No such file or directory
Even though the glib-object.h is present.
That's because the CFLAGS are improperly set, due to configure not
catching the error while setting them:
$ /opt/csw/bin/pkg-config --cflags gdk-pixbuf-2.0
sh: gnome-config: introuvable
Package libpng15 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpng15.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libpng15', required by 'GdkPixbuf', not found
but is this a problem with the reverse dependencies on libpng? Is this
just a matter of rebuilding them?
Riccardo, since you upgraded, can you please list those issues and
contact each maintainer, in order to fix the dependencies in the right
order?
Sure, how do I do it best, how do I have a list of those issues?
libpng-dev has just once reverse dependency, however
http://www.opencsw.org/packages/CSWlibpng15-15/
shows 49 reverese dependencies, many of them don't appear to have a
maintainer/uploader.
Thank you,
Riccardo
