No package 'libffi' found

I try to install glib-2.30.2 from http://ftp.gnome.org/pub/GNOME/sources/glib/2.30/ ang get the following error:

./configure

Code:

configure: error: Package requirements (libffi >= 3.0.0) were not met:



No package 'libffi' found



Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.

rpm -q libffi -> libffi-3.0.5-3.2
rpm -q libffi-devel -> libffi-devel-3.0.5-3.2.

I have installed and configured pkg-confign

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

I also find the followin errors on when trying to install gtk+-3.2.3 from http://developer.gnome.org/gtk3/stab...-building.html

Code:

configure: error: Package requirements (glib-2.0 >= 2.29.14    atk >= 2.1.5    pango >= 1.29.0    cairo >= 1.10.0    cairo-gobject >= 1.10.0    gdk-pixbuf-2.0 >= 2.23.5) were not met:

No package 'atk' found

No package 'pango' found

No package 'cairo' found

No package 'cairo-gobject' found

No package 'gdk-pixbuf-2.0' found

also

rpm -q atk -> atk-1.28.0-2
rpm -q pango -> pango-1.28.1-3
rpm -q cairo -> cairo-1.8.8-3.1
rpm -q cairo-gobject -> (nothing)
rpm -q gdk-pixbuf-2.0 -> gdk-pixbuf-0.22.0-38

can anyone who has experienced the same problem help me?

Haven't experienced the problem, as all of the packages you're trying to install are available in my distro's (Fedora) repositories, so a simple yum install <requestedpackage> will install the requested package and any dependencies. You're clearly using an rpm-based distro. Why not use your your distro's package manager?

Well, I have all the required libraries installed from my destro rpm repositories. The problem comes when gtk+3.2.3 is NOT available to any of those. My target is to install gtk+3.2.3.

So I try to compile it myself, using the instruction from GTK+ web site. Starting from gtk+ which requests glib-2.0.0 or greater, there is also no available glib-2.*.* in any repo.

So, it comes up that it doesn't find the olready installed libraries to their normal place,
and that's why guys in GTK+ website suggest to use pkg-config tool,
to instruct process and find those libraries before compiling.

I wrote this thread,if someone has any knowledge of how to use this pkg-config tool, cause I haven't use this tool before. Thank you for your answer.

I'd guess, that you are excluding /usr/lib/pkgconfig/ with this :
( from post #1 ) PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

May be this will work :
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

I tested that. Same results

also please note:

Code:

$ whereis pkg-config

pkg-config: /usr/bin/pkg-config /usr/local/bin/pkg-config /usr/share/man/man1/pkg-config.1.gz



$ ls -l /usr/local/lib/pkg-config

Thank you.

May be this : PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/***
isn't working at all.

I always use this command :
export PKG_CONFIG_LIBDIR=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig/
&& ./configure && make

The export command is temporary : Will reset to default,
when you exit the terminal.

Quote:

pkg-config: /usr/bin/pkg-config /usr/local/bin/pkg-config

Only /usr/bin/pkg-config is supposed to be installed.
May be uninstall the extra pkg-config in /usr/local/ .

.

man pages in linux are to instruct users how to use the packages, inside pkg-config I see this:

Code:

METADATA FILE SYNTAX

      To add a library to the set of packages pkg-config knows about, simply install a .pc file. You should install this file to libdir/pkgconfig.



      Here is an example file:

      # This is a comment

      prefix=/home/hp/unst  # this defines a variable

      exec_prefix=${prefix}  # defining another variable in terms of the first

      libdir=${exec_prefix}/lib

      includedir=${prefix}/include



      Name: GObject                            # human-readable name

      Description: Object/type system for GLib # human-readable description

      Version: 1.3.1

      URL: http://www.gtk.org

      Requires: glib-2.0 = 1.3.1

      Conflicts: foobar <= 4.5

      Libs: -L${libdir} -lgobject-1.3

      Libs.private: -lm

      Cflags: -I${includedir}/glib-2.0 -I${libdir}/glib/include



      You would normally generate the file using configure, so that the prefix, etc. are set to the proper values.  The GNU Autoconf manual recommends generating files like .pc

      files at build time rather than configure time, so when you build the .pc file is a matter of taste and preference.

I don't understand that "... using configure, so th... " also I don't understand how to uninstall this /usr/local/lib/pkgconfig folder (i just moved it), I think it was placed there when I sourced the pkg-config tool and no /usr/lib/pkgconfig exists. I also see .pc files incide the glib sources, which I can't understand: where do they know where my libraries exist in my system? How were they generated there?

I followed your instructions with no luck. I'm burned!!
What's this libffi library anyway.. what a mess

____________ SOLVED ____________

OK I just sourced libffi and magically the libffi.pc file appeared on /usr/local/lib/pkgconfig folder
and also the glib-2.30.2 was installed correctly.

just take EXTRA care that you do not fubar the system with a second and different glib and gtk

if /usr/local is in the system path and gnome or the OS ( cent6) find the different packages .You will be in for some problems

in building the dev tree for gimp it is VERY easy to make a normal every day typo and royally mess up the system
