Every time the mouse entered the clutter stage I got a segmentation fault. I debugged it a little but I didn't find the cause, just a null pointer in the handling of CLUTTER_ENTER event inside clutter. But the gtk-clutter-events example in clutter-gtk worked fine, so it was a problem related to cheese I guess, or something I forgot to update, or some mixture caused by my attempts to build cheese gtk3 branch, I don't really know.
A little tired, I decided I'd set up the development enviroment in my fedora partition (which I barely used before, so it was in a "fresh install" state), something I wanted to try anyway to see how it worked.
It's a long and tedious process:
download from git, build and install jhbuild
create .jhbuildrc
(already had it)
install some packages needed by jhbuild sanitycheck
(jhbuild bootstrap)
jhbuild sanitycheck keeps complaining about automake 1.8/1.9 after bootstrap,
(install automake 1.8.5 and 1.8 from sources, still complains, ignore it and continue)(this was a mistake I had to deal with later)
cannot connect to gnome git, public key issue after copying existing keys from ubuntu partition to .ssh in fedora partition
(change keys owner from root to laura)
g++ is missing
(install "c++ support for gcc")

I tried to think ways to make this a little bit better. For starters,
1) Add the unneeded packages to skip.extend in .jhbuildrc
This is the complete list of 47 packages built by "jhbuild build cheese":
$ jhbuild list cheese gnome-common intltool rarian gnome-doc-utils gtk-doc glib fontconfig pixman cairo gobject-introspection pango atk gdk-pixbuf shared-mime-info gtk+ libIDL ORBit2 gtk+-3 dbus-glib gconf gstreamer liboil gudev gst-plugins-base gst-plugins-good json-glib clutter clutter-gst clutter-gtk libgee gnome-video-effects libcroco librsvg startup-notification libnotify libnl libgnome-keyring libproxy glib-networking libsoup gvfs gnome-desktop libgweather libical libgdata evolution-data-server cheese
But I don't know yet which can be skipped and which are really needed.
2) Add some needed packages to that list: vala, libcanberra, gst-plugins-bad
3) Everytime I got an error complaining about a package not found, I searched its name in the package manager gui and added the related devel package. It would be great if somehow, jhbuild didn't stop with a prompt every time this happened, and listed instead all the errors about missing packages together after trying to configure the complete list of packages. Then try to add all the devel packages together somehow. (script? different gui for package manager that allows to list all currently installed packages with their devel counterparts and then "select all"?)
4) thinking about potential new contributors that are just starting, the error messages don't imply the solution at all, this causes lots of google searches. I can't think of an automated solution for this, since the error messages are written by people, and trying to set standards or guidelines for them will not be really effective. They vary a lot and are sometimes misleading. (Check the X11 cases).
5) ?
And on top of all this, this is the result:
Some minor variations in the results when starting cheese with different effects already selected.
I know that for the frei0r effects to work I need to install frei0r-plugins from fedora repos. (those would be the brownish "Cartoon", "Che Guevara", "Chrome", etc.). About the other effects, I had the same exact subset of effects that behaved a little different in ubuntu too, but with different symptoms. I haven't investigated what is exactly the difference between them.
These are the three different sets:
| Look fine | Garbled (pink hue in ubuntu) | frei0r |
|---|---|---|
Bulge Heat Kaleidoscope Mirror Pinch Sepia Square Stretch Twirl X-Ray | No Effect Dice Edge Historical Hulk Kung-Fu Mauve Noir/Blanc Optical Illusion Quark Radioactive Ripple Saturation Shagadelic Vertigo Warp Waveform | Cartoon Che Guevara Chrome Distortion Invertion Sobel Time Delay |
The exact behavior of these bugs depends on which effect was already seleted when starting cheese.
But anyway, now the mouse entering the stage does not cause a segmentation fault. Now I can keep testing my faceoverlay plugin that still have some problems when selecting and deselecting the effect (changing from READY to NULL and from NULL to READY in the pipeline), and that was the goal of all this. ;)

Ouch, sounds horrible. :/
For what it's worth, "sudo yum-builddep cheese" on Fedora will attempt to install everything required to build cheese. (It tries to install 47 new packages on my system, so that's probably a decent chunk of the ones you had to add manually..)
mmh, pink hue?
do you happen to have a non-english locale set — at least for numeric values?
oh, and yes: we really suck at making development easier for newcomers. jhbuild tries to ease the pain, but as you've seen firsthand some dependencies have to come from your distribution — otherwise jhbuild would have to compile the whole system from scratch, and that would not be a good thing.
it would be really nice to have a full "required dependencies" set that downloaded the distribution packages needed to start hacking a gnome application; the gnome-shell build script tries to do that, so maybe we could have a gnome-build-setup script maintained alongside the jhbuild modulesets.
I've seen weird corruption like that in Clutter when running on the second screen with my Intel video card.
@printf.net: do'h! if only I had known about that command before! :D
You are my HERO!!!!!!
Your install notes and fix procedures saved my day!!!!
THANK YOU LAURA!!!
YOU ARE MY HERO!!!!!!
Laura, your install notes and fix procedures really saved my day!
THANK YOU!!!!
Congratulations Laura , terrific work .
Congratulations Laura , terrific.
This post's helped me with the jhbuild problem
configure: error: NSPR headers not found. Use --with-nspr-includes
Thanks !
I suggest to add
module_autogenargs['evolution-data-server']=' --with-nspr-includes=/usr/include/nspr4/ --with-nss-includes=/usr/include/nss3'
in your jhbuildrc in order to not to do the ./configure by hand
