Contributed software for use with the Antelope Environmental Monitoring System from BRTT, Inc.

Maintained by members of the Antelope Users Group.

The Antelope Contrib source code is available on GitHub

Inclusion in Antelope

BRTT includes compiled versions of the software in this repository with every release of Antelope, subject to some basic quality control guidelines. The Contributing section below contains some guidelines.

Layout of the antelope_contrib Git repository

Each directory containing Antelope code is expected to contain a Makefile written in the antelopemakefile(5) format. The Antelope build process will not build any directory that does not contain a Makefile.

Code in this repository is laid out in a few top-level dirctories.

  • first - Code that is necessary for antelope_contrib to compile properly. Built before anything else. Use sparingly.
  • lib - C shared libraries, Perl modules, and Python modules
  • bin - The bin directory contains executables.
    • bin/rt - Code that talks to instruments typically lives under bin/rt.
    • bin/export - Code that allows other software packages to use Antelope data lives in bin/export.
  • data - Third-party language bindings for PHP, and Java, plus data-only files like travel time databases and instrument response curves.
  • nobuild - Older code that is abandoned by the author or no longer works with the current version of Antelope, but may be interesting to others


All code in this repository requires a working Antelope installation. Additionally, the Antelope environment must be configured in your shell environment.

Historically, this repository was checked out in $ANTELOPE/src, but can be checked out to any location that the user desires.

Compilation is handled by the UNIX make command. Most of the Makefiles in this repository make use of the antelopemake(5) mechanism, which is a bit of Antelope-specific syntacic sugar and macros.

Initial setup

In the instructions below, make sure to substitute the correct version of Antelope.

You may also choose to check out the contributed code to another location than $ANTELOPE/src.

For Bourne shells:

. /opt/antelope/5.6/
git clone src

For C shells:

source /opt/antelope/5.6/setup.csh
git clone src


Some of the code in this repository needs to link against third party software applications and libraries that may not be present on all systems. In order for this code to compile, the Makefiles for some code use the localmake mechanism to read a set of pre-defined paths to libraries and other applications. No defaults are provided - you must run the localmake_config command to set up these macros. Basic boot-strapping for localmake looks like this:

# Install the localmake_config command from source
cd $ANTELOPE/src/first/localmake_config
make Include

# Install the localmake command
cd ../localmake
make Include; make; make install
cd ../../

# Run localmake_config to define the paths to various third-party software


cd $ANTELOPE/src # or where ever you checked out the repository
make Include
make install


Code Contribution Rules

As a rule, all code in this repository MUST at a minimum:

  1. Compile cleanly on the supported Antelope platforms (RHEL 6+ and Mac OSX 10.8+)
  2. Contain a Makefile set up to use the antelopemake(5) rules, and with the SUBDIR macro set to /contrib (See the Example Makefile below)
  3. Contain a man page describing how to use the program or library. This can be formatted by hand or created with a documentation package like Doxygen, sphinx, pod2man, or javadoc.
  4. Contain a file called LICENSE that clearly states the license that program is released with. See the Licensing section below for acceptable licenses.

Development Process

  1. Fork it (
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Commit your changes (git commit -am 'Add some feature')
  4. Push to the branch (git push origin my-new-feature)
  5. Create a new Pull Request

Example Makefile

BIN = myprog
MAN1 = $(BIN).1



All code in this repository is expected to be readily distributed. In order for pre-compiled versions of your code to be included with the Antelope distribution, it must be accompanied by a LICENSE file, and be of a type that lends itself to inclusion in commercial packages. Generally speaking, BSD and MIT style licenses are ok, but GNU GPL and LGPL are not.
