WindNinja

WindNinja#

WindMapper requires a working WindNinja install and intalling WindMapper does not installs WindNinja. Windmapper depends on the WindNinja program to compute the windfields. WindNinja may be installed separately, or it can be built and installed via Conan. These instructions will show how to do so via Conan.

Note

Building WindNinja with conan will use a different gdal library than what was used for the python bindings! This is ok, just please be aware of this.

  • conan >= 1.21

  • cmake >= 3.16

  • C++11 compiler (gcc 7.x+ recommended)

Setup conan#

Install conan

pip install conan

If cmake is not installed system wide:

pip install cmake

or install via system package manager.

Initialize a new conan profile (if required)

conan profile new default --detect
conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
conan remote add CHM https://api.bintray.com/conan/chrismarsh/CHM
conan profile update settings.compiler.cppstd=14 default

conan needs to be told to use new C++11 ABI. If using clang (e.g., MacOs), do

conan profile update settings.compiler.libcxx=libc++ default  #with clang

and if using gcc, do

conan profile update settings.compiler.libcxx=libstdc++11 default  #with gcc

If you change compilers, such as on a cluster with a modules system, you can rerun

conan profile new default --detect --force

to detect the new compiler settings. The cppstd and libcxx settings need to be reapplied once this is done.

and then install WindNinja from Conan

mkdir /opt/windninja && cd /opt/windninja #this could be any directory you wish to install to
conan install windninja/3.7.5@CHM/stable -g deploy

Note

Currently the MacOS OpenMP build of WindNinja does not work firelab/windninja#355
