So what external application should do? Add own copy of headers to sources or try use BlueZ copy of headers.

I think about user try to use one version of libpcap and try to change kernel to older (there can be old kernel API). -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
