If we use GLib version less than 2.32 (more precisely < 2.31.2) then the following build error may occure in a 32 bit. cc1: warnings being treated as errors gobex/gobex-apparam.c: In function ‘g_obex_apparam_set_bytes’: gobex/gobex-apparam.c:176:38: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_uint8’: gobex/gobex-apparam.c:243:43: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_uint16’: gobex/gobex-apparam.c:261:43: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_uint32’: gobex/gobex-apparam.c:282:43: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_uint64’: gobex/gobex-apparam.c:303:43: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_string’: gobex/gobex-apparam.c:324:43: error: cast to pointer from integer of different size gobex/gobex-apparam.c: In function ‘g_obex_apparam_get_bytes’: gobex/gobex-apparam.c:342:43: error: cast to pointer from integer of different size make[1]: *** [gobex/gobex-apparam.o] Error 1 make: *** [all] Error 2 --- Reference: GLib tree: Commit: 16292dd753cb63f8ccb2267644aefbd2632dd52c Author: Lucas De Marchi <lucas.demarchi@xxxxxxxxxxxxxx> Date: Thu Oct 6 11:18:03 2011 -0300 Fix G*_TO_POINTER casts on 32 bits If we don't do the cast to the proper size in 32 bits, things like below doesn't work: uint8_t u = 20; void *p; p = GUINT_TO_POINTER(u); Signed-off-by: Colin Walters <walters@xxxxxxxxxx> Thanks Luiz for giving this reference.
