s/printer/pcap module/ - I was thinking tcpdump, not libpcap. pcap-usb-linux.c includes what should be standard Linux headers, plus including some headers under #ifdefs set by configure. However, it assumes that, for example, struct usbdevfs_ctrltransfer will always be defined, even if <linux/usbdevice_fs.h> doesn't exist. That probably needs to be fixed; I'll look at that. For other structures and #defines, pcap-usb-linux.c has its own versions; this makes me a little nervous - I'll have to see whether the authors of the code had a reason why 1) they had to do that and 2) it was safe to do that. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
