Hi Orson, I tested your patch without any issue on W7 32 bits and gdb. With -DBUILD_SMALL_DEBUG_FILES=ON option, the binaries are about 20 time smaller than without this option. In fact on my 32 bits install, without this option, I cannot load pcbnew from Kicad or with gdb and load a medium complexity board: I am running out of memory. In countries using a comma as FP separator, there is a problem: When loading a bitmap, and perhaps some config files, a wxASSERT is displayed (see attached copy) I tried to fix this wxWidgets alert, but no luck. -- Jean-Pierre CHARRAS
