So after discovering that while I had libusb-devel-0.1 and libusb1-devel-1.0.3 installed on my RHEL-6 machine here (and ubuntu), gnuradio compiled against 0.1 despite 0.1 being "ancient and unsupported". I then removed libusb-devel and gnuradio fails to configure.

So just what is the status with libusb. Should it be compiling against libusb-0.1 or should it be compiling against libusb-1.0 and if so, why isn't configure finding libusb-1.0 on Ubuntu or RHEL-6? _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
