Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Configuration:
  -h, --help              display this help and exit

Installation directories:
  --prefix=PREFIX         install files in PREFIX [/usr/local/mdsplus]

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [PREFIX/bin]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --libdir=DIR            object code libraries [PREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]

Optional Features:
  --enable-debug=[yes/info/profile/no]
                          compile with debugging

                          Enable compile sanitizer with flavor in 
                          (memory | address | thread | undefined)

Optional Packages:
  --with-jdk=JDKDIR       specify location of java jdk
  --with-java_target=version
                          specify version of compiled mdsobjects classes (i.e.

                          --with-java_bootclasspath=bootclasspath
                          specify the bootclasspath option for use with
                          --with-java_target (i.e.
                          /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre/lib/rt.jar)

  --with-gsi=globus-location:flavor
                          Use globus gsi for mdsip communications
  --with-srb=srb-install-dir
                          Enable srb capabilities
  --with-labview=labview-top-dir
                          specify location of labview such as

  --with-readline=READLINE_DIR
                          look for the readline library in READLINE_DIR
  --with-xml-prefix=PFX   Prefix where libxml is installed (optional)

Some influential environment variables:
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CC          C compiler command
  CFLAGS      C compiler flags
  FC          Fortran compiler command
  FCFLAGS     Fortran compiler flags
  CPP         C preprocessor
  PYTHON      the Python interpreter

Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.
