The warnings below are all from the RTree library (a library we got from a public-domain source, very old C code): > index.c: In function ?Xastir_RTreeSearch?: > index.c:86: warning: cast from pointer to integer of different size Ugh. Just looked at that one. Turns out that in the RTree structure, there's an element called "child" that usually contains a pointer to a childe node of the tree. If the node is a leaf node, however, the child field (which is of type Node *) is re-used to hold the integer ID of the data record represented by that leaf node. So in a number of cases, there's casts to int of the contents of the child field --- the code is careful only to do so when the child field contains an integer, not a pointer, but it's throwing size warnings like that. Feh. line 86 casts a child field to an int. > index.c: In function ?Xastir_RTreeInsertRect2?: > index.c:147: warning: cast to pointer from integer of different size And that one is where it casts an int to a pointer to store in child. > index.c: In function ?Xastir_RTreeDeleteRect2?: > index.c:287: warning: cast to pointer from integer of different size And this one casts an int to a pointer to compare it to the contents of a child field. A bit messy, but since the code is carefully using the child field of the struct as an int only when it has in fact stored an int there, it won't be broken on 64-bit. Would be nice to be able to clean that up, though. The RTree code is essentially unmodified from the original library from which we took it (which was obtained from www.superliminal.com). -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM "It is better to live on your feet than to die with your knees." -- Mil Millington on running, in Instructions for Living Someone Else's Life _______________________________________________ Xastir-dev mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir-dev
