iLiad Need help getting started with gtk

tribble · 06-04-2007, 05:27 AM

Hi!

I am just starting to learn c++.
I used the developer vmware image to setup a dev environment.
I started scratchbox and i compiles fine.
i can get the busy led to flash and the screen to refresh and the pagebar to show the pagenumber i want.

What i want to do is paint anythin i want on the screen. But i have not really a clue on how to do that.

I was trying to include <gtk/gtk.h>, but it doesn't find the library. There are gtk 1.2 and 2.0 installed in the scratchbox environment. How do i get them to be included, when i compile the program?

ok, i hvae just simply made a symbolic link from "gtk" to "gtk-2.0/gtk". Now the program complies. But i get an error on the iliad:

./myprogram: error while loading shared libraries: libgtk-1.2.so.0: cannot open shared object file: No such file or directory

I thought the gtk libraries were installed on the iliad? What do i have to do to make my program load them correctly?

Only some of GTK is installed on the iLiad.

You'll may also find GTK frustrating to work with since it generally runs its own event loop processor making it difficult to properly refresh the iLiad's screen at the right times.

You might find the learning curve for Java to be less steep.

Hehe, you might be right. I have done some Java programming before and that was quite easy. But since the JVM seems to be quite castrated, i didnt even want to bother. On the other hand, i might give it a try, because so far, i havent gotten anywhere.

You pays your money and you takes your choice: castrated GTK or castrated Java. :behead:

At least you can run the Java on your PC before sending it to the iLiad.
