Description Christoph Bauer 2005-11-09 06:39:16 UTC
Hi,

I took from the FAQ this program:

#include <cairo.h>
int
main (int argc, char *argv[]) {
        cairo_surface_t *surface;
        surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32, 200, 100);
        cairo_t *cr;
        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_rgba (cr, 0.0, 0.3, 1.0, 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, "hw.png");
        cairo_surface_destroy (surface);
        return 0;
}

and get with the latest CVS cairo this:

Comment 1 Christoph Bauer 2005-11-09 06:40:15 UTC
cairo was compiled with mingw-gcc
Comment 2 Christoph Bauer 2005-11-09 08:38:26 UTC
I think my bug is a duplicate of #4692.

Without fonts cairo seems to work, even in my Tk-Cairo Widget/Win32-Backend :-)
Comment 3 Vladimir Vukicevic 2005-11-09 15:03:00 UTC
Yep, almost certainly a dup of bug 4692 .  Can you try with a non-static build,
or manually do some code munging to get the things initialized?  (I'd pull out
initializer code into a cairo_win32_init() or something temporarily.)
Comment 4 Christoph Bauer 2005-11-11 03:47:50 UTC
configure --help should mention, that --enable-shared is supported (but not default)

Yes, the dynamic build looks better:

a8-mask is expected to fail:
        image backend fails because libpixman only handles (stride %
sizeof(pixman_bits) == 0)

Then it hangs.
Comment 5 joachim 2007-03-21 01:19:42 UTC
Use:
surface = cairo_win32_surface_create_with_dib();
instead of:
surface = cairo_image_surface_create();

Otherwise, it seems _cairo_win32_initialize() is not called in static builds.
Comment 6 Chris Wilson 2008-10-10 16:00:59 UTC
How is the static win32 build fairing after the Great Mutex Upheaval of 2007 and the Build Revamp of 2008?
