GTK, C issue

[anti-net]

I am trying out with GTK and C/C++ and i am trying some tutorials on www.gtk.org/tutorial but having some issues with gtk.h

I have had this problem before and I install libgtk2.0-dev(http://packages.ubuntu.com/dapper/libdevel/libgtk2.0-dev) which i was informed will sort my little problem but has't, not sure where to look now, Anyone able to help?

Thanks, Greg

You're are going to have to post the exact problems you're having in order for us to have any idea what the problem is.

Opps Sorry the code I was trying was:

#include <gtk/gtk.h>

int main( int argc,
char *argv[] )
{
GtkWidget *window;

gtk_init (&argc, &argv);

window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_show (window);

gtk_main ();

return 0;
}
the errors I get when I compile it from Anjuta I get
"error: gtk/gtk.h"
"error: gtkWidget undeclared(first use in this function)
"error: (Each undeclared identifier is reported only once
"error: for each function it appears in.)
"error: 'window undeclard (first use in this function)
"error: 'GTK_WINDOW_TOPLEVEL' undeclared (frist use in this function)

I hope that is enough information to work out my problem.

anti-net,

What's the compiler command Anjuta is using to compile your program? And try this from the command line:

$ gcc -Wall `pkg-config gtk+-2.0 --cflags --libs` -o mybinary mysource.c

[mike41]

what is 'pkg-config'? How come without that cc option, it won't compile even though the header files are in fact in the include directory?

I tryed what Po0f suggested and I get

gtk2.c: In function ‘main’:
gtk2.c:6: error: ‘gtkWidget’ undeclared (first use in this function)
gtk2.c:6: error: (Each undeclared identifier is reported only once
gtk2.c:6: error: for each function it appears in.)
gtk2.c:6: error: ‘window’ undeclared (first use in this function)

from GCC. ](*,)

paste the whole compiler output, not just the error

I have 2 actions that worked for me:

1. Make sure the glib dev packages are installed.
2. In Anjuta o to Project->Properties->Packages
- add a module
- add the gtk package

Hope this helps

It is called GtkWidget, not gtkWidget.
