On the contrary, the meta files seem to be right - the "META@" header, and later the PNG files. That's normal. What's *not* normal is that mod_tile is serving the full meta tile instead of the png tiles inside the meta tile. Also, please look that the header of the meta tile contains a pointer to the tiles. e.g. in this meta tile of mine: 00000000 4d 45 54 41 40 00 00 00 00 00 00 00 00 00 00 00 |m...@...........| 00000010 00 00 00 00 14 02 00 00 64 21 00 00 00 00 00 00 |........d!......| 00000020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000210 00 00 00 00 89 50 4e 47 0d 0a 1a 0a 00 00 00 0d |.....PNG........| "14 02" = 0x0214 is the start of a tile, and "64 21" = 0x2164 is the lenght. Just in case, please check that you have that right in your meta tiles located in /var/lib/mod_tile. This will tell us if the problem is in renderd (faulty generation of meta tiles) or in mod_tile itself (faulty reading of meta tiles) > Any idea's where to start looking in renderd.c or gen_tile.cpp? BTW, my > platform is OpenSolaris 11.08 101b, all tools compiled using SunStudio CC. Hhhmm. Maybe the behaviour of SSCC and GCC are different, and the python scripts expect the behaviour of GCC. I can't tell.
