I went through the tutorial websites and wanted to write a code in GTK for the first time…
I was able to get good hint of the structure of the programs, since the programing structure is quite similar to the one in Java Swings… ( I was quite good in Java Swings) except that only the syntaxes and a very few things are different.
My first program in GTK is :
#include < gtk/gtk.h >
int main( int argc,
char *argv )
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
Happily saved my program as firstgtk.c 🙂
I learnt from http://www.gtk.org/tutorial1.2/gtk_tut-2.html#ss2.1 how to compile in simple syntax...
gcc -o hello firstgtk.c `gtk-config --cflags --libs`
Sadly... The machine started scolding me as...
Must specify package names on the command line
base.c:1:21: error: gtk/gtk.h: No such file or directory
base.c: In function ‘main’:
base.c:6: error: ‘GtkWidget’ undeclared (first use in this function)
base.c:6: error: (Each undeclared identifier is reported only once
base.c:6: error: for each function it appears in.)
base.c:6: error: ‘window’ undeclared (first use in this function)
base.c:9: error: ‘GTK_WINDOW_TOPLEVEL’ undeclared (first use in this function)
Honestly I don't know the issue... Again started searching for a better syntax for compiling the gtk program...
This time, http://library.gnome.org/devel/gtk-tutorial/2.17/c39.html gave me a better syntax as:
gcc firstgtk.c -o base `pkg-config --cflags --libs gtk+-2.0`
Cool... It worked well !!!
And now I just tried executing it as :
I was happy to see a small window 🙂
