Plugin Installation

Dependencies

Build System

• C++ compiler supporting -std=c++11 (e.g. >= g++ 4.8 or >= clang++ 3.4)
• GYP

Libraries

• boost_system

  • = 1.57

• boost_thread

  • = 1.57

• mapnik

  • = 3.0.8

• jvm

  • = JDK 7

• geowave

  • = 0.8.7

  • source
  • docs

Test Libraries

• gtest

  • = 1.7.0

Runtime Environment/Jars

• Java Runtime Environment

  • = 7

• GeoWave Runtime Jar

  • = 0.8.7

• GeoWave Ingest Jar

  • = 0.8.7

  • Required for test

Configuration

We use GYP as our build system. You can setup a custom configuration by specifying variables in config.gypi

Here is a list of variables which you can override:

• boost_home
  • boost_includes
  • boost_libs
• geowave_home
  • geowave_includes
  • geowave_libs
  • geowave_runtime_jar
• java_home
  • java_include_path
  • java_include_path2
  • java_jvm_lib
• mapnik_config
  • mapnik_includes
  • mapnik_libs
  • mapnik_name
• gtest_includes
• gtest_libs

Once you have created config.gypi, you are ready to proceed to the build step.

Building

We provide a simple Makefile wrapper which can be used as follows:

make && make install

This will compile the geowave.input plugin and install it to the directory pointed to by:

./mapnik_config --input-plugins

The release library is built by default, but you can build the debug library using:

make debug

For more details, or to build directly with GYP, check out the contents of the Makefile.

Testing

Configuration

First, download the GeoWave runtime and ingest jars contained within the jace-source packages provided by GeoWave here.

Next, create two environment variables which point to the runtime and ingest jars:

export GEOWAVE_RUNTIME_JAR=/path/to/jar
export GEOWAVE_INGEST_JAR=/path/to/jar

Running Tests

Once configured, you can run the tests locally using the Makefile wrapper as follows:

make test
