It looks to me like a normal configure run with an informative message
about what backends (used by Pango itself to finally render and display
the text) will be built. Continue the install process. It should make
the pangoxft.pc file this time, because Xft is listed as a backend.

Is there a -devel RPM that needs installed? Does 'pkg-config --cflags
glib-2.0' produce -I flags for a couple of directories that actually
exist and have header files in them? (That's only a sane question if
'pkg-config --modversion glib-2.0' comes up with '2.4.1'.)

Have you read the installation guide, linked to from the download page?
http://developer.gnome.org/doc/API/2.4/gtk/gtk-building.html

Have you read config.log? Sounds like /usr/bin/pkg-config isn't looking
in /usr/local/lib/pkgconfig. You'll need to set PKG_CONFIG_PATH, and
probably LD_LIBRARY_PATH too or the next run will complain pkg-config
found 2.4 but the linker didn't.

Google can ;)

Add this line to the appropriate gtkrc:
module_path "/opt/gnome/lib/gtk-2.0/2.2.0/engines"

I suspect that is for gtk-2 and the other engine might be for gtk-1.

That should be fine; that's how I build my chroot jails. :)

You should really look into static linking (-static flag to gcc) for
your program, though. If nothing else is running to share the libraries
with, you're not going to see any advantage from using shared libraries.

As stated, Mozilla is looking for GTK 1.x. If you want to compile
against GTK 2.x instead, you can put this line in .mozconfig (or pass
the argument to configure, depending on how you're building):

ac_add_options --enable-default-toolkit=gtk2

I assume pkg-config will work since you managed to install GTK.

HTH. Further questions about building Mozilla should probably go to a

pkg-config is right, the linker is wrong. All possible solutions are

You probably want to install fontconfig, freetype, and xft as well...
although they may be on the system already. Try with
PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/local/lib/pkgconfig before doing
anything drastic.

This error says "pkg-config is working fine, but the linker isn't"; so
you can either set LD_LIBRARY_PATH, or add /usr/local/lib to
/etc/ld.so.conf (and run ldconfig). I forget which way is recommended.

Instead of "forever", it's also possible to set it for one command:
prompt$ LD_LIBRARY_PATH=/usr/local/lib ./configure

Or for every command until exiting the shell:
prompt$ export LD_LIBRARY_PATH=/usr/local/lib

gtk-1.x should be left alone; gtk-2 won't disturb it at all. At minimum,
the gtk-2 versions under the same prefix would have to be removed.
(Compiling with other versions later would probably require setting
PKG_CONFIG_PATH.)

It looks like it worked just fine: the messages look like warnings
because the first invocation uses -c (compile only) with the libraries.
Editing the Makefile so that the rules to generate .o files didn't
include "--libs" should fix that.

This isn't the real config.log; it's the output of configure. configure
should have produced the config.log in the same directory, and near the
end, it should contain the exact program, compiler command, and error
messages involved.

However, given that it's picking up /usr/bin/pkg-config, the most likely
culprit is that GLib is installed under /usr/local or whatever you
passed as --prefix to its configure script. Thus, it may help to run as:

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure

Modify as appropriate for your environment. If you haven't seen it, the
full install guide may also be handy:

http://developer.gnome.org/doc/API/2.2/gtk/gtk-building.html

/usr/lib, /usr/local/lib, $(PREFIX), $LDFLAGS, anything nonstandard in
/etc/ld.so.conf on Linux... and that's just for libraries, not includes.
The cure is worse than the disease.

GTK+ simply expects anyone compiling from source to give it a clean
system to run on. If things were broken before it arrived, that can
hardly be blamed on GTK+ itself.

/tmp is traditionally cleaned on boot. In certain environments, random
files may also get removed by the system administrator if the partition
gets full.

Incidentally, trying to store *another* file somewhere is going to run
into all the same configure problems as finding the files in the first
place.

Oh, I misunderstood the problem. /usr/bin/pkg-config is _still there_,
oblivious to /usr/local/*, and run by default because it's earlier in
$PATH.

In that case, is there any situation in which /usr/bin/pkg-config should
NOT look in /usr/local/lib/pkgconfig? Havoc, as maintainer, what are
your thoughts? Should this be changed?

That suggests pkg-config needs ${PREFIX}/lib/pkgconfig included in its
default path. It's not user error if a piece of software doesn't pay
attention to where it installed itself (or was asked to install itself).

Have you read:
http://developer.gnome.org/doc/API/2.0/gtk/gtk-building.html

It explains all the dependencies and (eventually) what order to compile
everything in. Generally, all the latest packages should work together;
if you can find the release announcements, it should also list the
versions of dependent libraries of that release.

In case you didn't understand what Peter said, the focus-out-event and
activate signals have different call signatures. If you change the
signal, the callback function needs to be modified accordingly.
Normally, the compiler catches improper numbers of arguments, but that
doesn't work here due to unavoidable casting to GCallback.

void activate_callback(GtkEntry *entry, gpointer user_data) {
  ...
}

gboolean focus_out_callback(GtkWidget *widget, GdkEventFocus *event,
gpointer user_data) {
  ...
}

...
  g_signal_connect(entry_box, "signal-name", signal_callback, data);

GTK/GDK takes care of passing in the relevant entry/widget/event, but
the same function can't be used in both cases. user_data is whatever
user_data was supplied to the g_signal_connect() call.

I'm not very familiar with printing, but I don't think GTK supports it
itself. I believe GNOME offers printing capability, but I'm not sure of
what; I don't know if it can print random GTK widgets.

GTK supports several formats (e.g. PNG and JPEG) through pixbuf loaders.
Whether PHP-GTK can use them isn't really a question for gtk-list.

I can't answer the rest of your questions, but for this one: no, that's
considered harmful. Translations, themes, user configuration (font faces
and sizes), and probably more variables affect the size of text to be
laid out. It's probably possible with an image-only design, but that's
not as generally useful.

For something to be printed, you should probably consider using an
actual page description language like PostScript or possibly TeX (which
I am not so familiar with).

GIMP 1.2.x relies on GTK 1.2. The development GIMP (1.3.x) uses GTK 2.

Check out the tutorial, especially the Theory of Signals and Callbacks.




A detailed reference for GTK+, GLib, and friends is at
, once you're done with the tutorial.
