[NooBeee]

what would i apitude(can this be used as a verb?) if i want to start tinkering around with gtk+ with C?

[sdrubolo]

sudo aptitude install gnome-core-devel build-essential

and then, here is a tutorial.
www.gtk.org/tutorial.

moreover, here there should be a post you may find interesting, http://ubuntuforums.org/showthread.php?t=400956

i tried that but it didn't work--compiling a test helloworld file results in a unknown header error

gcc: pkg-config --cflags --libs gtk+-2.0: No such file or directory
gtk.c:1:21: error: gtk/gtk.h: No such file or directory

that's my same problem.
when you compile try this that should work
gcc -o helloworld helloworld.c `pkg-config --cflags --libs gtk+-2.0`

[NooBeee]

lol....there was nothing wrong my gtk install.... i was tying a comma instead of the `

[chihuonbk]

I am now facing the same problem,too. What was wrong? Or may be the command sudo aptitude install gnome-core-devel build-essential still not enough.

[nvteighen]

I fear that's some obsolete method... or one that is applied from some other distro... whatever, I never had heard of such gnome-core-devel package before.

Use:

sudo apt-get install libgtk2.0-dev

(and also install "build-essential" if you haven't).

But also, I highly recommend you to install GTK+'s docs and the very nice GNOME's Devhelp documentation browser (which you will be able to access from Applications->Programming):

sudo apt-get install libgtk2.0-doc devhelp

[jespdj]

You compile a GTK+ program like this:

gcc hello.c -o hello `pkg-config --cflags --libs gtk+-2.0`

Note the use of backticks ` instead of straight quotes '.

thanks nvteighen and jespdj...

its work now...

so install gtk in ubuntu:

sudo apt get install gnome-core-devel build-essential install libgtk2.0-dev libgtk2.0-doc devhelp
