3.6.4 ONLY builds with the jansson and libusb included in cgminer (which is libusb-1.0.16-rc10, NOT libusbx). It ignores any installed libraries on your machine since it's the only way I can guarantee people are using the most stable libraries. As for it hanging on closing, it's a clusterfuck that I've never been able to completely fix due to millions of threads going wild and no clean way to shut it down with some things never returning. Blame me.
Con,
you must know that it is trivial for a ArchLinux maintainer to sed your configure.ac script to do whatever he wants. Here is a snippet of the PKGBUILD script:
# We have latest jansson and libusb - just use them
sed "s|ac_subdirs_all='compat/libusb\-1.0\ncompat/jansson-2.5'||" -i ./configure
sed 's|subdirs="$subdirs compat/libusb\-1.0"||' -i ./configure
sed 's|subdirs="$subdirs compat/jansson\-2.5"||' -i ./configure
sed 's|LIBUSB_LIBS="compat/libusb-1.0/libusb/.libs/libusb-1.0.a"|LIBUSB_LIBS=-lusb-1.0|' -i ./configure
sed 's|JANSSON_LIBS="compat/jansson-2.5/src/.libs/libjansson.a"|JANSSON_LIBS=-ljansson|' -i ./configure
sed 's|compat/Makefile ||' -i ./configure
sed 's|JANSSON_INCLUDES = -I$(top_srcdir)/compat/jansson-2.5/src||' -i ./Makefile.in
sed 's|USBUTILS_INCLUDES = -I$(top_srcdir)/compat/libusb\-1.0/libusb|USBUTILS_INCLUDES = -I/usr/include/libusb-1.0|' -i ./Makefile.in
sed 's|SUBDIRS = lib compat ccan|SUBDIRS = lib ccan|' -i ./Makefile.in
rm -r compat
but hey thanks for the suggestion to try out the git version. I'll do that and report back if it fix my problem.
Thank you very much!
