Hi @leopagamonci See this section of the FindMPI CMake docs: https://cmake.org/cmake/help/latest/module/FindMPI.html#variables-for-locating-mpi. I would try setting the MPI_HOME environment variable to the directory containing the mpi libraries. For example export MPI_HOME=/usr/lib/
cmake ..Let me know how this works for you. |

Ah thanks, I didn't fully read the post initially. Can you print the value of YAML_CPP_INCLUDE_DIRS in CMake? message("YAML_CPP_INCLUDE_DIRS ${YAML_CPP_INCLUDE_DIRS}") |

Do you mean adding this line inside the "CMakeLists.txt" file at the directory "glue-codes/openfast-cpp"? By now I added that line in the file like this: include_directories(${YAML_CPP_INCLUDE_DIRS})
message("YAML_CPP_INCLUDE_DIRS ${YAML_CPP_INCLUDE_DIRS}")
include_directories(${HDF5_INCLUDES})
include_directories(${HDF5_INCLUDE_DIR})
include_directories(${ZLIB_INCLUDES})
include_directories(${LIBXML2_INCLUDE_DIR})
include_directories(${CMAKE_SOURCE_DIR}/modules/openfast-library/src/)
include_directories(${CMAKE_BINARY_DIR}/modules/openfoam/)
include_directories(${CMAKE_BINARY_DIR}/modules/supercontroller/)
include_directories(${MPI_INCLUDE_PATH})After rebuilding I obtained this lines: Is there any other file that I should find inside "build" folder? |

I don't know if it can be useful, anyway I also attach the CMakeCache with some info about yaml: |

@leopagamonci Yes you've added the print statement correctly and you can see in the cmake output that the value of I'll dig into it a little further today on a linux computer - I use Mac primarily. |

Hi @rafmudaf, Do you have news about a possible solution? I am still blocked in this problem. Thanks, Leonardo |

Hi @rafmudaf , I have worked on the message("YAML_CPP_INCLUDE_DIRS ${yaml-cpp_INCLUDE_DIR}")I get the following during building: The find_package (PkgConfig REQUIRED)
pkg_search_module (yaml-cpp_PC yaml-cpp)
find_library (yaml-cpp_LIBRARY
NAMES yaml-cpp
HINTS
${yaml-cpp_PC_LIBDIR}
${yaml-cpp_PC_LIBRARY_DIRS})
**find_path (yaml-cpp_INCLUDE_DIR
NAMES yaml-cpp/yaml.h
PATH_SUFFIXES yaml-cpp
HINTS
/usr/include/
/usr/include/yaml-cpp/)**
mark_as_advanced (
yaml-cpp_LIBRARY
yaml-cpp_INCLUDE_DIR)
include (FindPackageHandleStandardArgs)
find_package_handle_standard_args (yaml-cpp
REQUIRED_VARS
yaml-cpp_LIBRARY
yaml-cpp_INCLUDE_DIR

set_target_properties (yaml-cpp::yaml-cpp

IMPORTED_LOCATION ${yaml-cpp_LIBRARY}
INTERFACE_INCLUDE_DIRECTORIES ${yaml-cpp_INCLUDE_DIRS})
endif ()I am pretty sure that I am missing something, maybe the correct match of the names inside the CMake file and the Findyaml one. Thanks, Leonardo |

By trying the settings above, I get the following errors during building: |

As an alternative to the methods we've discussed in other replies here, I'm wondering if the best solution is to simply distribute the C++ API as a shared object through conda. @leopagamonci do you need to change the source code? If not, I'll compile the library on my linux computer and post it here to see how it works. Sound good? |

Hi @rafmudaf, Thank you very much for the library file. In the meanwhile, I managed to try solving the problem, because at a certain moment we would need to modify the source code. Probably I have found the source of the error: inside the "/build/glue-codes/openfast-cpp/CMakeFiles/openfastcpp.dir/link.txt" file, after building, the list of commands didn't accounted for the "libyaml-cpp.so" library, so I tried to add it manually, and it seems that it worked. By now I can make all, install openfastcpp and so on. My question now is: in a similar manner as for SOWFA (https://www.nrel.gov/wind/nwtc/assets/pdfs/sowfa-tutorial.pdf), I would add the so-called "libfast.a" static library into my C coded udf, but maybe some time has passed and the name of the static library has changed. Which name should it have and where I can find it? PS maybe I should had mentioned it before, but all of this was needed in order to interface OpenFAST to a C written udf. Is the C++ API also suitable for C written codes? And if yes, is it the right way to move on? Thank you again, Leonardo |

Thank you very much for the info. So you confirm that the C++ interface won't work on a C udf? Are there any more details about it? |

👉 @gantech @leopagamonci you could try out a simpler test case. Create a C driver and try to initialize OpenFAST through the C++ API. There is an old C driver for OpenFAST, but it uses a different set of routines in the I recently removed this in the |

First of all, as you mentioned the C driver, I got a doubt: could I somehow access to the OpenFAST modules from my C udf without the C++ API? Otherwise, I will try with this test case and let you know. In this case, I please ask you where I can find an example of how to initialize OpenFAST through the C++ API, or, alternatively, if you suggest me to move as follows:

Hi,
I am trying to build OpenFAST v3.0 with C++API enabled on a Linux machine with cmake3 command but I get this:
cmake3 -B build
-- Enabling Fortran 2008 features
-- A library with LAPACK API found.
-- Setting system file as: src/SysGnuLinux.f90

See also "/home/pagamonci/OpenFAST/openfast2/openfast/build/CMakeFiles/CMakeError.log".
Here are the two log files outputted:
CMakeError.log

From a first overview, it seems that"mpi.h" and "mpif.h" files are not found. What would be the quickest solution to solve this problem? Moreover, I am wondering if I missed other problems, so I kindly ask you what you would suggest
Thank you in advance for you kind response,
