WARNING!
If you plan on building the path64 compiler, do not rely on the
following instructions.

Instead clone https://github.com/pathscale/path64-suite and follow the
README file in that repository.


Dependencies:
    cmake-2.8.1 or later


1. Create a build directory and go there
    % mkdir $BUILDDIR
    % cd $BUILDDIR

2. Run cmake
    % cmake -DCMAKE_INSTALL_PREFIX=$INSTDIR $SOURCEDIR

   Possible options (incomplete list):
      -DPATH64_ENABLE_TARGETS=<targets>  e.g. "x86_64"
      -DCMAKE_BUILD_TYPE=<Debug|Release>
      -DCMAKE_Fortran_COMPILER=<compiler>
      -DPATH64_ENABLE_HUGEPAGES=<ON|OFF>

   Options that should be specified for each target in <targets>:
      -DPSC_LIBSUPCPP_PATH_<target>=<path to libsupc++ library>
      -DPSC_LIBSTDCPP_PATH_<target>=<path to libstdc++ library>
      -DPSC_LIBGCC_PATH_<target>=<path to libgcc library>
      -DPSC_LIBGCC_EH_PATH_<target>=<path to libgcc_eh library>
      -DPSC_LIBGCC_S_PATH_<target>=<path to libgcc_s library>

   Example for x86_64 target:
   cmake -DCMAKE_BUILD_TYPE=Debug \
         -DPATH64_ENABLE_TARGETS="x86_64" \
         -DPATH64_ENABLE_FORTRAN=ON \
         -DPSC_LIBSUPCPP_PATH_x86_64=/usr/lib/gcc/x86_64-linux-gnu/4.4 \
         -DPSC_LIBSTDCPP_PATH_x86_64=/usr/lib/gcc/x86_64-linux-gnu/4.4 \
         -DPSC_LIBGCC_PATH_x86_64=/usr/lib/gcc/x86_64-linux-gnu/4.4 \
         -DPSC_LIBGCC_EH_PATH_x86_64=/usr/lib/gcc/x86_64-linux-gnu/4.4 \
         -DPSC_LIBGCC_S_PATH_x86_64=/usr/lib/gcc/x86_64-linux-gnu/4.4 \
         <path_to_sources>

3. Run make:
    % make
 To increase build verbosity
    % make VERBOSE=1
