Hiya, I've been playing around with libnfc, which recently added the std=c99 flag to the compilation. Unfortunately this uses libusb-0.1 or libusb-compat-0.1, which fail with c99, and produce the following sorts of errors: libtool: compile: i686-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I.. -pthread -I/usr/include/PCSC -DHAVE_PCSC_LITE -O2 -mtune=core2 -pipe -ggdb -std=c99 -MT libnfc_la-dev_pn531.lo -MD -MP -MF .deps/libnfc_la-dev_pn531.Tpo -c dev_pn531.c -fPIC -DPIC -o .libs/libnfc_la-dev_pn531.o In file included from dev_pn531.c:27: /usr/include/usb.h:73: error: expected specifier-qualifier-list before 'u_int8_t' /usr/include/usb.h:79: error: expected specifier-qualifier-list before 'u_int8_t' I talked to dsd about it and he said that libusb-0.1 wasn't maintained anymore and that upstream should consider libusb-1.0. Upstream said that libusb-1.0 wasn't on most major distributions, and so they'd be sticking with libusb-0.1 for the time being, but that most other distributions had patched their code to be ANSI compliant. They pointed me at the Debian patch [1]. Is there any chance we could apply this to the Gentoo version as well? The Debian patch assumes an earlier attribute/packed patch has been applied. I'm going to attach a patch that doesn't require anything else, and works (with modification to apply to either usb.h.in or libusb/usb.h depending on the package) on both libusb and libusb-compat. Thanks... 5:) [1] http://patch-tracking.debian.net/patch/series/view/libusb/2:0.1.12-13/01_ansi.diff

I could be totally mistaken on this but on first sight it looks as if your patch introduced a circular dependency: ZeusGentoo2 ~ # emerge -upvD world These are the packages that would be merged, in order: Calculating dependencies... done!

Andre: That's not a circular dep, but rather a conflict between what's declared. sane-backends is saying it MUST have libusb:0, while you presently have libusb-compat installed.

OK I unmerged libusb-compat manually first, which removed the blocker. An emerge --depclean further removed libusb-1.0.1. Not sure that this is what I want but this bug suggests that's the case...
Sorry, I missed the original reason for this bug with Andre's interjection. It's added to both libusb-compat and the original libusb-0* now. Give me a shout about libnfc sometime soon via IRC please?
