Description Hans Breuer 2005-04-08 18:23:19 UTC 
using glib/gutils.h with g++ gives the following compile time error
(and I can't make any sense of the code either;) :

Comment 1 Tor Lillqvist 2005-04-09 00:45:48 UTC 
Does adding a (gconstpointer) cast in front of the &g_win32_get_system_data_dirs
help?
Comment 2 Matthias Clasen 2005-07-19 15:33:18 UTC 
Tor, whats up with this ? Why is there a non-inlined function body in gutils.h
on win32 ? That doesn't make much sense to me...
Comment 3 Tor Lillqvist 2005-07-19 15:48:00 UTC 
The idea is that when code in some DLL calls g_get_system_data_dirs(), it will
automagically call g_win32_get_system_data_dirs_for_module(), passing it a
pointer to code in the DLL itself.
Comment 4 Tor Lillqvist 2005-07-19 15:55:40 UTC 
But I guess the function should be made G_INLINE_FUNC.
Comment 5 Tor Lillqvist 2005-07-20 08:37:45 UTC 
Should be fixed now:

2005-07-20  Tor Lillqvist  <tml@novell.com>

	* glib/gutils.h (g_win32_get_system_data_dirs): Make this an
	inline function. Define it only if G_CAN_INLINE and not
	C++. (#173098)
