Java Bindings for Cuspatial

This project is a Java layer bridging Java user and libcuspatial.so

Follow these instructions to create local builds and installation of librmm, libcudf and cudf-java, and libcuspatial

Build and Install Dependencies:

1. libcudf and cudf-java

1.1) Follow instructions on this page for libcudf: https://github.com/rapidsai/cudf/blob/branch-0.11/CONTRIBUTING.md#script-to-build-cudf-from-source, but append two more cmake config flags -DARROW_STATIC_LIB=ON -DBoost_USE_STATIC_LIBS=ON, changing

$ cmake .. -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX -DCMAKE_CXX11_ABI=ON

to

$ cmake .. -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX -DCMAKE_CXX11_ABI=ON -DARROW_STATIC_LIB=ON -DBoost_USE_STATIC_LIBS=ON

Make sure to make install after make. DO NOT use the build.sh script to build libcudf.so

1.2) Follow the instructions in ${CUDF_HOME}/java/README.md to build and install cuDF product JAR and test JAR

$ cd ${CUDF_HOME}/java 
$ mvn clean install

NOTE:

1. Following above steps you will have conda env cudf_dev which is required for subsequent builds.
2. libcudf.so will be installed under conda env cudf_dev.
3. libcudfJni.so will be built by maven pom.
4. cuDF JARs will be installed to maven local.

2. librmm (header-only)

export RMM_HOME=${pwd}/rmm and git clone source into $RMM_HOME. Follow instructions on this page: https://github.com/rapidsai/rmm, section Script to build RMM from source

$ cd ${RMM_HOME}/
$ ./build.sh librmm

NOTE:

1. The build.sh script does installation by default.
2. The destination is conda env cudf_dev.

3. libcuspatial

Follow the instructions on this page for libcuspatial: https://github.com/rapidsai/cuspatial

$ cd ${CUSPATIAL_HOME}/
$ ./build.sh libcuspatial tests

NOTE:

1. Require env RMM_HOME, CUDF_HOME, CUSPATIAL_HOME, and conda env cudf_dev.

Build cuspatial-java

$ cd ${CUSPATIAL_HOME}/java
$ mvn clean install

NOTE:

1. cuspatialJni.so will be built by maven pom.
2. Unit tests of Cuspatial-java will run during the JAR build.
