or use shortcut command

gcc -o hello $(pkg-config --cflags --libs cairo) hello.c

4: GUI dev

(1) build eclipse + cdt (google for details)

(2) new c project, set project properties as,  then run project

5: hello.c code

#include <cairo.h>

int main (int argc, char *argv[])
{
        cairo_surface_t *surface =
                cairo_image_surface_create (CAIRO_FORMAT_ARGB32, 240, 80);
        cairo_t *cr =
                cairo_create (surface);

        cairo_select_font_face (cr, "serif", CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_BOLD);
        cairo_set_font_size (cr, 32.0);
        cairo_set_source_rgb (cr, 0.0, 0.0, 1.0);
        cairo_move_to (cr, 10.0, 50.0);
        cairo_show_text (cr, "Hello, world");

        cairo_destroy (cr);
        cairo_surface_write_to_png (surface, "hello.png");
        cairo_surface_destroy (surface);
        return 0;
