This device comes with an installation process in which a "configure" shell script builds a make file for subsequent Make and Make Install stages.
For me this fails with an error due to not having found libusb, with the suggestion of installing libusb or setting some environment variable arguments for LIBUSB_CFLAGS and LIBUSB_LIBS.
I do have libusb installed.
In poking around the problem I have discovered pkg-config which the shell script uses to test for these things but in trying it out from a terminal it just doesn't seem to return anything.
Specifically, I have found /usr/share/pkgconfig and /usr/lib/pkgconfig which contains libpcsclite.pc, which features somewhere in the install script, but calling for example pkg-config libpcsclite from the terminal gives just no response.
Can anyone suggest how to proceed from here? What next new thing do I have to learn?
