Package: libfltk1.3-dev
Version: 1.3.2-2
Severity: normal
Some FLTK API functions are actually macros, and some of these call xlib
directly. For instance, say I have the following file tst.cc:
#include <FL/fl_draw.H>
void f(void)
{
Fl_Offscreen offscreen = fl_create_offscreen(100,100);
}
When the preprocessor transforms this file, it does this:
$ gcc -o- -E /tmp/tst.cc | awk '/void f\(/,0'
void f(void)
{
Fl_Offscreen offscreen = XCreatePixmap(fl_display,
(Fl_Surface_Device::surface() == Fl_Display_Device::display_device() ?
fl_window : fl_xid_(Fl::first_window()) ) , 100, 100, fl_visual->depth);
}
Note that this calls XCreatePixmap() directly. Thus tst.o uses libX11 directly,
thus the application that uses tst.o needs to be linked with -lX11. The
DT_NEEDED flag won't help here. Adding -lX11 into the output of 'pkg-config
--libs' should make this work.
