Chapel Compiler Release: README
===============================

This is the 1.11.0 release of the Chapel compiler, intended to give
potential users a look at what we're doing and the opportunity to
provide us with feedback.  See the LICENSE file for the release's
licensing terms.


-----------
Quick Start
-----------

The following instructions are designed to get you up and running with
Chapel with a minimum of fuss.  Note that building and using Chapel in
this mode disables enhanced runtime options and optional language
capabilities in the interest of a simple and clean build.


1) Make sure that your shell is in the directory containing this
   README file.  For example:

        cd ~/chapel-1.11.0


2) Set up your environment to use Chapel in "Quick Start" mode.

   If you use...                         then type...

   ...a bash-compatible shell (bash/zsh) source util/quickstart/setchplenv.bash
   ...a csh-compatible shell (csh/tcsh)  source util/quickstart/setchplenv.csh
   ...the fish shell (fish)              . util/quickstart/setchplenv.fish
   ...the Bourne shell (sh)              . util/quickstart/setchplenv.sh

   You must be in the top-level Chapel directory for these command
   scripts to work properly.  Note that there is no requirement to use
   these scripts long-term, they are merely designed to get new users
   up and running quickly.  See doc/README.chplenv for a complete
   description of Chapel's environment variables and their options.

   If you use a shell other than the ones listed above and are able to
   create an equivalent util/quickstart/setchplenv.* script for it,
   please consider contributing a copy of it back to the project for
   inclusion in the next release.


3) Build the compiler and runtime libraries using:

        gmake

   or if your default make is GNU make compatible (as on Mac OS X or
   Cygwin), use:

        make

   Parallel build execution (e.g. `gmake -j`) is supported.

4) csh/tcsh users only: Update your shell's path cache using:

        rehash


5) To ensure you have installed Chapel properly, you can optionally
   run an automatic sanity check using a few example programs:

        gmake check

   or:

        make check


6) Compile an example program using:

        chpl -o hello examples/hello.chpl


7) Execute the resulting executable:

        ./hello


8) Experiment with Chapel in Quick Start mode to your heart's content.

   Once you are comfortable with Chapel and interested in using a
   full-featured version in the preferred configuration:

   a) Open up a new shell to avoid inheriting the previous environment
      settings.

   b) Repeat steps 1-7 above, but in Step 2, use util/setchplenv.*
      instead of util/quickstart/setchplenv.*

   This will set up your environment to use Chapel in the preferred
   configuration.  Making this configuration will involve building one
   or more third-party packages which will increase the overall build
   time.  If you run into any portability issues, please let us know
   at chapel_info@cray.com.


9) If you plan to do performance studies of Chapel programs, be sure
   to (a) use the full-featured version and (b) read the PERFORMANCE
   file in this directory to avoid common pitfalls.
