Install from source

Install from source#

The LUE source code can be obtained from the LUE GitHub project page. CMake is used to configure and generate project files for building LUE.

The following CMake variables are used to determine which targets to build:

Variable

Default

Effect

LUE_BUILD_DATA_MODEL

TRUE

Build data model C++ API

LUE_BUILD_FRAMEWORK

TRUE

Build modelling framework

LUE_BUILD_VIEW

TRUE

Build data model viewer

LUE_BUILD_DOCUMENTATION

FALSE

Build API documentation

LUE_BUILD_QA

FALSE

Build QA targets

Here is an example session of building the default LUE targets and installing them in $HOME/lue_install:

cd /tmp
git clone https://github.com/computationalgeography/lue.git
cd lue
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$HOME/lue_install ..
cmake --build . --target install

Also, you can check the LUE GitHub workflow scripts behind the LUE GitHub C/I actions to see how LUE can be built on various platforms.

Targets#

Data model#

Optional features:

Variable

Default

Effect

LUE_DATA_MODEL_WITH_PYTHON_API

FALSE

Build data model Python API

LUE_DATA_MODEL_WITH_UTILITIES

FALSE

Build command line utilities

Dependencies#

  • HDF5 C, Boost, fmt

  • LUE_DATA_MODEL_WITH_PYTHON_API: Python, pybind11, NumPy, Guidelines Support libraries

  • LUE_DATA_MODEL_WITH_UTILITIES: Docopt, GDAL, Nlohmann JSON

Framework#

Optional features:

Variable

Default

Effect

LUE_FRAMEWORK_WITH_PYTHON_API

FALSE

Build modelling framework Python API

Dependencies#

  • Boost, Docopt, fmt, GDAL, HPX, LUE data model, Kokkos mdspan

  • LUE_FRAMEWORK_WITH_PYTHON_API: Python, pybind11, NumPy

View#

Dependencies#

  • Dear ImGUI, Docopt, fmt, GLFW, Nlohmann JSON, OpenGL

Documentation#

Dependencies#

  • Breathe, Doxygen, Graphviz, Jupyter-Book, Sphinx

QA#

Optional features:

Variable

Default

Effect

LUE_QA_WITH_PYTHON_API

FALSE

Build QA Python API

LUE_QA_WITH_TESTS

FALSE

Build test targets

LUE_QA_TEST_NR_LOCALITIES_PER_TEST

1

Localities used when testing the framework

LUE_QA_TEST_NR_THREADS_PER_LOCALITY

1

Threads per locality used when testing the framework

LUE_QA_TEST_HPX_RUNWRAPPER

none

Runwrapper to use (see hpxrun.py)

LUE_QA_TEST_HPX_PARCELPORT

tcp

Parcelport to use (see hpxrun.py)

Note

Changing LUE_QA_TEST_NR_LOCALITIES_PER_TEST and LUE_QA_TEST_NR_THREADS_PER_LOCALITY is only relevant for tests that depend on the HPX library. Using multiple localities (LUE_QA_TEST_NR_LOCALITIES_PER_TEST > 1), requires that HPX is built with support for networking.

Dependencies#

  • Nlohmann JSON

  • LUE_QA_WITH_TESTS: Boost filesystem, system, unit-test framework libraries

  • LUE_QA_WITH_PYTHON_API: pybind11, Python

Dependencies#

There are at least three options for installing prerequisite libraries and tools:

  1. Install using platform specific package manager

  2. Install using Conan, either before building LUE or by the LUE build scripts

  3. Build by the LUE build scripts

The next variables determine what happens in each case by default.

LUE_HAVE_FOO:

  • TRUE: Search for Foo in standard locations

  • FALSE: Install Foo using Conan

Variable

WIN32

APPLE

LUE_HAVE_BOOST

FALSE

Some prerequisite libraries can optionally be built by the LUE project itself. The following variables are used to decide whether or not that is the case. By default, they are not set.

Variable

Effect when set

LUE_BUILD_HPX

Build the HPX library

LUE_BUILD_OTF2

Build the OTF2 library (optionally required by HPX)
