The problem is that you're trying to write a Pixmap into a Window
which doesn't exist yet, hence the X error. A better way to add your
image is
[...]
fl_initialize(&argc, argv, 0, 0, 0);
form1 = fl_bgn_form(FL_NO_BOX, 200, 200);
fl_add_box(FL_FLAT_BOX,0,0,200,200,"");
pixmap = fl_add_pixmap(FL_NORMAL_PIXMAP, 0, 0, 8, 8, "");
fl_set_pixmap_data( pixmap, smallBlock ); /* Do this */
fl_end_form();
fl_show_form(form1, FL_PLACE_CENTERFREE, FL_FULLBORDER,"Form 1");
fl_do_forms();
[...]
Alternatively, move the call to fl_set_pixmap_pixmap() to *after* the
fl_show_form() call:
[...]
fl_initialize(&argc, argv, 0, 0, 0);
pixId = fl_create_from_pixmapdata(fl_default_window(), smallBlock,
&width, &height, 0, NULL, NULL,
0);
form1 = fl_bgn_form(FL_NO_BOX, 200, 200);
fl_add_box(FL_FLAT_BOX,0,0,200,200,"");
pixmap = fl_add_pixmap(FL_NORMAL_PIXMAP, 0, 0, 8, 8, "");
fl_end_form();
fl_show_form(form1, FL_PLACE_CENTERFREE, FL_FULLBORDER,"Form 1");
fl_set_pixmap_pixmap(pixmap, pixId, 0); /* Move to here so there's */
/* Window to draw into */
fl_do_forms();
[...]
