The Quantis software for Linux is provided by id Quantique in a
directory structure like so:

  /
  |- Quantis-USB
  |      |
  |      \- src
  |          |
  |          |- windows
  |          \- linux
  |               |
  |               |- driver
  |               |- include
  |               |- lib
  |               \- qrng
  |
  |- Quantis-PCI
         |
         \- src
             |
             |- freebsd
             |- solaris
             |- windows
             \- linux
                 |
                 |- driver
                 |- include
                 |- lib
                 \- qrng


The library must first be compiled (and the driver must be compiled
and installed for it to be useful.)  Instructions are provided in the
file install_usergd.html in the root of the software distribution.

There are no installation routines or pkg-config files included for
the libraries so the TkResolver++ configure script must be told where
they are.  It needs to be told about both the include and lib
directories.


The Quantis-USB and Quantis-PCI libraries implement the same API, in a
file called quantis.h.  This file is included under the include/
directory of both trees so the option for the include directory is
indifferent to which version of the library it comes from.  The option
is:

  --with-quantis-include-dir
                          directory containing Quantis library header


The library object files are named differently and so there are
separate options for the USB and PCI versions:

  --with-quantis-usb-dir  directory containing Quantis USB library
  --with-quantis-pci-dir  directory containing Quantis PCI library

These options are mutually exclusive; only one of the libraries can be
used by TkResolver++.


Eg, if the Quantis software is in a directory ${HOME}/quantis-cd, the
following options will enable TkResolver++ to use the USB library:

  ./configure \
  --with-quantis-include-dir=${HOME}/quantis-cd/Quantis-USB/src/linux/include \
  --with-quantis-usb-dir=${HOME}/quantis-cd/Quantis-USB/src/linux/lib

and these options will enable use of the PCI library:

  ./configure \
  --with-quantis-include-dir=${HOME}/quantis-cd/Quantis-PCI/src/linux/include \
  --with-quantis-pci-dir=${HOME}/quantis-cd/Quantis-PCI/src/linux/lib


The author does not have access to a Quantis device so it would be
helpful if users with access could report (to rah@bash.sh) both
success and failure in using the device.
