GTK and Eclipse?

[Nuvious]

I've set up the eclipse cdt and it successfully compiled the hello world program. I'm not trying to run this simple GTK program:

/*
 *File name: window.c
 */

#include <gtk/gtk.h>
#include <glib.h>

int main (int argc, char *argv[])
{
  /*-- Declare the GTK Widgets used in the program --*/
  GtkWidget *window;

  /*--  Initialize GTK --*/
  gtk_init (&argc, &argv);

  /*-- Create the new window --*/
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

  /*-- Display the window --*/
  gtk_widget_show(window);

  /*-- Start the GTK event loop --*/
  gtk_main();

  /*-- Return 0 if exit is successful --*/
  return 0;
}

I get the No such file or directory errors on gtk/gtk.h and glib.h includes and I'm sure it's because I don't have my Project build setting set up right. I've tried appending several extended commands to the g++ build string with no success. Anyone know how to set up the Eclipse CDT to be able to compile GTK programs? Thanks in advanced for any serious replies!

I managed to configure NetBeans to compile GTK apps by simply guessing how to do that, doing the same with Eclipse - I failed, even after googling a bit. So I decided to stick with NetBeans and I'm very happy, if no one answers your question I suggest trying what I did.

Are you sure that you have installed the GTK development libraries? Not having installed it would produce an error like that.

Are you sure that you have installed the GTK development libraries? Not having installed it would produce an error like that.

I had not installed it (thought it was pre-installed with ubuntu). However, now I have the libraries included via the Directories part of the Project Build Configurations in Project Properties but am now getting this error:

Severity and Description	Path	Resource	Location	Creation Time	Id
/usr/include/glib-2.0/glib/garray.h error: ‘array’ was not declared in this scope		Test	line 94	1211840857378	1133

And my includes are set up as follows:

/usr/include/gtk-2.0
/usr/include/glib-2.0/glib
/usr/include/c++/4.2.3
/usr/include/glib-2.0

I figured 'array' should've been covered by the second include. Is this the correct way to include items? Should I be using a different method? If not, why doesn't it recognize 'array' (which I believe is included via glibconfig.h).

Thanks for your replies!

I'm having the same problem... I have gtk2.0-dev, glib2.0-dev packages installed, but I still get a cascading series of errors when compiling a simplified version of this program in Eclipse.

Help?

Thanks.

I did get it to compile, but I had to explicitly add all the following to my project:

/usr/include/gtk-2.0
/usr/lib/gtk-2.0/include
/usr/include/glib-2.0
/usr/lib/glib-2.0/include
/usr/include/cairo
/usr/include/atk-1.0
/usr/include/pango-1.0

which got rid of the errors. I had to add /usr/lib to my lib search path and gtk to my lib list (no surprise there).

I thought there was supposed to be an environment variable that defined the INCLUDE path, or C_INCLUDE_PATH, or CPLUS_INCLUDE_PATH. It's not set on my system. Where should I set it, and will Eclipse respect it when it's there?

Thanks!

Combining information from a number of sources, as long as you have the GTK source libraries installed (check in /usr/include/ for gtk-2.0), you can set up Eclipse to work with GTK files like this. This is a workaround, and I'm sure there's a better way

* Create a new 'C Project', Project type 'Executable', toolchain 'Linux GCC', selecting defaults for all pages
* Once the project is created, right-click on the project name and choose 'properties' (Alt-Enter)
* Expand the C/C++ Build menu and select 'Settings'
* In "GCC C Compiler", change the 'Command line pattern', add

`pkg-config --cflags --libs gtk+-2.0`

after

${COMMAND}

Example:

${COMMAND} `pkg-config --cflags --libs gtk+-2.0` ${FLAGS} ${OUTPUT_FLAG}${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}

* Do the same in GCC C linker

You should now be able to build and run GTK source files from Eclipse.

I have successfully compiled and run both tutorial files from http://library.gnome.org/devel/gtk-t...table/c39.html using the above settings.

In case anyone else stumbles onto this post like I did...
Those are backticks (key above tab) not single quotes. Explanation of the compilation options here - http://library.gnome.org/devel/gtk-t...able/x111.html

Here's a way to do what cro (above) has done but a little more elegantly and easier to use and remember.

In eclipse

window->preferences

expand c/c++ then select Managed Build

click on new (define a variable)

Name: gtkc
Value: `pkg-config --cflags --libs gtk+-2.0`
(note backwards single quotes are important)

click OK

Repeat if you want to set up one for c++ as well using the c++ variables.

click apply
click Ok

Now you have one or two compiler variables you can apply to any c or c++ project as shown below.

select your project (in this case a c project) then

project->properties

select c/c++ Build

under GCC C Compiler-> Miscellaneous

in Other Flags add ${gtkc} at the end

select GCC C Linker->Miscellaneous

in Linker Flags add ${gtkc}

click apply

click OK.

Have fun.

thanks sms0611, it works perfectly!
