LinuxQuestions.org - Installing GTK

- Ubuntu (https://www.linuxquestions.org/questions/ubuntu-63/)

- - Installing GTK (https://www.linuxquestions.org/questions/ubuntu-63/installing-gtk-565441/)

I want to install GTK as I want to learn about GUI programming, and also implement GUI into a few programs of my own. I am completely capable of install GTK from source if I really wanted to, but I would rather just apt-get it, and save some time. I have looked through synaptic, and nothing has caught my attention; though I may have missed something. If that is true, then I am sorry for posting this, otherwise, what package should I apt-get?

GTK will already be installed on your system, as it is a critical system component if you are using graphical applications on the machine.

Hmm...there isn't a header in /usr/include:

In the gtk tutorials, they #include <gtk/gtk.h>, and there is no gtk directory, nor a gtk.h.

I do however have these directories:

Code:

/usr/lib$ echo gtk*

gtk-2.0 gtkhtml gtk-sharp-2.0

Maybe a whereis or slocate (which outputs more lines then can fit in the terminal) command?

Strange, it must be an Ubuntu-specific thing then. On my Slackware machine, the GTK header files are included with the binary packages.

Code:

tj@T-Bird:/usr/lib$ locate "gtk.h"          

/usr/include/gtk-1.2/gtk/gtk.h

/usr/include/gtk-2.0/gtk/gtk.h

/usr/include/wx-2.8/wx/gtk/win_gtk.h

/usr/include/wx-2.8/wx/gtk/assertdlg_gtk.h

/usr/include/wx-2.8/wx/gtk/tbargtk.h

/usr/include/wx-2.8/wx/gtk/treeentry_gtk.h

/usr/include/pygtk-2.0/pygtk/pygtk.h

As you can see, they are right where the GTK tutorials are referencing them "/gtk/gtk.h". Perhaps there is some development GTK package that needs to be installed. Check for something along the lines of "libgtk-dev".

My system (Mepis) did not install this by default--even though GTK itself is there.

The package is libgtk2.0-dev

MS3FGX:
You are comparing Slackware to Ubuntu; obviously Slackware wins that. The only reason I don't run Slackware is my wireless card. And Ubuntu doesn't even come with gcc installed by default. You expect the gtk headers to be there too?

I had installed that package and gtk.h is in /usr/include/gtk-2.0/gtk/gtk.h by default, and #include <gtk/gtk.h> works fine.

Thanks for your help.
