# Chapel Quickstart Instructions¶

These instructions are designed to help you get started with a source distribution of the latest Chapel release.

In the following instructions, note that building and using Chapel as described in steps 2-5 disables optional and advanced features in the interest of getting you a clean build as quickly as possible. Later sections explain how to re-build in the preferred configuration and how to enable more features, such as distributed memory execution.

1. See prereqs.rst for more information about system tools and packages you may need to have installed to build and run Chapel.

3. If you are using a source release, build Chapel in a quickstart configuration. The quickstart script used below is designed to help you get started with Chapel. After that, you may want to switch to a more full-featured configuration. See using-a-more-full-featured-chapel below.

1. Expand the source release if you haven't already:

tar xzf chapel-1.18.0.tar.gz

2. Make sure that your shell is in the directory containing QUICKSTART.rst, for example:

cd chapel-1.18.0

3. Set up your environment for Chapel's Quickstart mode. If you are using a shell other than bash, see quickstart-with-other-shells below.

source util/quickstart/setchplenv.bash

4. Use GNU make to build Chapel. On some systems, you will have to use gmake. See building.rst for more information about building Chapel.

make

5. Optionally, check that your Chapel build is working correctly

make check

4. Compile an example program:

chpl -o hello examples/hello.chpl

5. Run the resulting executable:

./hello

6. Experiment with Chapel in this Quickstart mode to your heart's content. Once you are comfortable with Chapel and interested in using a full-featured version in the preferred configuration, see the next section.

## Using Chapel in Multi-Locale Mode¶

All of the instructions above describe how to run Chapel programs in a single-locale (shared-memory) mode. To run using multiple locales (distributed memory), please refer to multilocale.rst.
