Installation

Requirements

• C++17 compiler

• cmake 3.16+

• fmt

• ExodusII

  • Usually depends on NetCDF and HDF5

CMake

Standard installation steps should build the library:

$ cd /path/to/exodusIIcpp
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make install

Embedding into project

• Copy files from include/ and src/ directory into your project directory

• Add CMakeLists.txt file in that directory:

  project(exodusIIcpp)
  
  add_library(${PROJECT_NAME}
     STATIC
         exodusIIcppElementBlock.cpp
         exodusIIcppFile.cpp
         exodusIIcppNodeSet.cpp
         exodusIIcppSideSet.cpp
  )
  
  target_link_libraries(
     ${PROJECT_NAME}
     PUBLIC
         ${EXODUSII_LIBRARY}
  )
  
  install(
     DIRECTORY
         ${PROJECT_SOURCE_DIR}
     DESTINATION
         ${CMAKE_INSTALL_INCLUDEDIR}
     FILES_MATCHING
         PATTERN "*.h"
  )
  

• Copy the FindExodsuII.cmake and FindNetCDF.cmake files from the cmake/ directory into your project

• Use the following code to find the dependencies

  find_package(NetCDF REQUIRED)
  find_package(ExodusII REQUIRED)
  find_package(HDF5 COMPONENTS C)
  

  Note

  ExodusII depends on NetCDF. Newer versions also depend on HDF5.

  This will set the EXODUSII_LIBRARY variable we are using in the CMakeLists.txt above.

• Do not forget to add your directory in your main CMakeLists.txt via:

  add_subdirectory(path/to/the/dir/with/exodusIIcpp/files)
