For those finding interesting the experimentation, here are some tips:
1. Install Ubuntu 10.04.
2. Download and install Harbour compiler for Ubuntu: http://sourceforge.net/projects/harbour ... b/download
3. Install Development files for the GTK+ library. You can do it with Synaptic Package Manager (libgtk2.0-dev).
4. Create a file called test.prg (with the code below) and build it with hbmk test `pkg-config --cflags --libs gtk+-2.0` command . Run it with ./test
test.prg:
Code: Select all
