NOTE: see bottom of this file for suggested configurations on particular ANL
machines.

0 - Checkout, build, and install the trunk version of ROSS. At the time of
release (0.3.0), ROSS's latest commit hash was c04babe, so this revision is
"safe" in the unlikely case incompatible changes come along in the future.

    git clone http://github.com/carothersc/ROSS.git
    # optional: git checkout c04babe
    cd ROSS
    mkdir build
    cd build
	# note: other options for ARCH include i386 (for 32 bit machines),
	# bgp, and bgq (for Blue Gene systems)
    ARCH=x86_64 CC=mpicc CXX=mpicxx cmake -DCMAKE_INSTALL_PREFIX=../install ../
    make -j 3
    make install

    <the result should be that the latest version of ROSS is installed in the 
    ROSS/install/ directory>

1 - If you are building codes-base directly from the repository, run

    ./prepare.sh

2 - Configure codes-base. This can be done in the source directory or in a
    dedicated build directory if you prefer out-of-tree builds.  The CC
    environment variable must refer to an MPI compiler.

    mkdir build
    cd build
    ../configure --with-ross=/path/to/ross/install --prefix=/path/to/codes-base/install CC=mpicc

    To enable network tracing with dumpi, use optional --with-dumpi = /path/to/dumpi/install with configure.

3 - Build and install codes-base

    make && make install

4 - (optional) run test programs

    make tests && make check

5 - codes-base uses flex and bison (or lex and yacc) to generate several
    parsers. These tools auto-generate C source files. To get around versioning
    issues, we've distributed the auto-generated sources directly. To remove
    all of the autogenerated files for these parsers, execute

    make maintainer-clean-local


Machine-specific configurations:
----------------
- Fusion (ANL): add the following keys to your ~/.soft file and run "resoft"
  prior to following the steps described in this file:

  +python-2.7.3
  +autoconf-2.68
  +git
  +cmake

Notes on using the clang static analyzer
-----------------
- follow steps 0-2 as shown above, with one exception:
  - add the following argument to configure:
    CFLAGS=-I<path_to_your_mpi_include_directory>
- edit Makefile, and delete the "CC = mpicc" (or similar) line
- run "scan-build --use-cc=mpicc make"
