Sofa linking unsuccesful

[oscar93gonmar]

Hi,
I have updated Tudat and checkout the FullOrbitDetermination branch to use the SOFA package. During the installation the following error appeared: boost libraries not found: "Library not loaded" "Image not found" . I found the solution to the issue in GitHub and I modified the CMake files and now it seems to be properly installed. However, when I call any function in sofaTimeConversions.h I get another issue: symbol(s) not found for architecture x86_64. With the following compile output message:

There is an already closed issue with the same error message but it didn't work for me after changing the Cmake configuration-> Cmake_c_compiler:string
Thanks in advance,
Oscar

Hi Oscar,

Could you attach in a file:

• The CMakeLists of your application
• The full compile output in a .txt file

I think I know what is causing the problem (sofa is not added as a link library in your CMake file) but I want to check to make sure,

Yes I attach them here, sorry I didn't see your message until now.
Thanks, Oscar

Hi Oscar,

Yes, I think my suspicion is correct. First, add Sofa as a library to your project by adding (for instance on line 159 after including spice):

option(USE_SOFA "build Tudat with Sofa enabled" ON) # OFF is the default
if(NOT USE_SOFA)
message(STATUS "SOFA disabled!")
add_definitions(-DUSE_SOFA=0)
else()
message(STATUS "SOFA enabled!")
add_definitions(-DUSE_SOFA=1)

Find SOFA library on local system.

find_package(Sofa)

Include Sofa directories.

if(NOT APPLE OR APPLE_INCLUDE_FORCE)
include_directories(SYSTEM AFTER "${SOFA_INCLUDE_DIR}")
else( )
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -isystem "${SOFA_INCLUDE_DIR}"")
endif( )
endif()

Then add:

if(USE_SOFA)
list(APPEND TUDAT_EXTERNAL_LIBRARIES tudat_sofa_interface sofa)
list(APPEND TUDAT_ESTIMATION_LIBRARIES tudat_sofa_interface sofa)
endif()

Let me know if this works out,

Best regards,

Dominic

Hi Dominic,
After doing it, I am getting an error saying that: including_directories given empty-string as include directory. I attach the compile output
compile_output.txt

thanks for your help,
Oscar

Your applications folder should have a 'CMakeModules' directory somewhere. I'm guessing that it doesn't contain a FindSofa.cmake file. You can copy this file from tudatBundle/external/CMake to the CMakeModules directory of your application. Let me know if this resolves it,
