Hello,

I am trying to learn GTK programming, and thus wrote a simple program which displays an empty window.

#include "gtk-1.2/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);
}

I compiled it using command gcc -I/opt/gnome/include/gtk-1.2/gtk/ first.c
and got the error

first.c:1:29: gtk-1.2/gtk/gtk.h: No such file or directory
first.c: In function `main':
first.c:3: error: `GtkWidget' undeclared (first use in this function)
first.c:3: error: (Each undeclared identifier is reported only once
first.c:3: error: for each function it appears in.)
first.c:3: error: `window' undeclared (first use in this function)
first.c:4: error: stray '\' in program
first.c:4: error: stray '\' in program
first.c:5: error: `GTK_WINDOW_TOPLEVEL' undeclared (first use in this function)
first.c: At top level:
first.c:9: error: stray '\2' in program

how come gcc could not find the location of gtk.h (already specified by -I option).
when i issued locate gtk.h then the output shows the same location.

what does this means? how can i remove this error?

Thanks & Regards

Try replacing the include line to:

#include <gtk/gtk.h>

and try to compile with:

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

Then if it compiles, run it with:

./test

You might also want to take a look into anjuta. It's a great IDE for C and GTK programming

Good luck!

P.S: I assume you have gtk-devel packages installed too

Oops, sorry. If you are using gtk 1.2 ratter then 2, my above post won't work. Take a look in here instead:

http://www.gtk.org/tutorial1.2/

I never used gtk1.2 before, sorry

Thanks for your reply Megaman X,

I compiled with the command gcc you_source.c -o test `pkg-config --cflags --libs gtk+-2.0`
it reduced the errors, but still there are some..

first.c: In function `main':
first.c:5: error: stray '\' in program
first.c:5: error: stray '\' in program
first.c: At top level:
first.c:10: error: stray '\2' in program

what does this mean?

About anjuta.... i tried to install it form source while making it gave me an error saying
glib-mkenums command not found i have already placed this problem

Thanks it worked the tutorial which i am referring has \& sign instead of &,
which gave the following errors.

Cool, no problems RohanShrivastav. Congratulations .
