auryn installations step for mac

[Nazehs]

I have tried following the steps provided for linux installations and it seems not working for me. Because of the below error

-- Checking for module 'mpi-c'
--   No package 'mpi-c' found
-- Could NOT find MPI_C (missing: MPI_C_LIB_NAMES MPI_C_WORKS) 
-- Checking for module 'mpi-cxx'
--   No package 'mpi-cxx' found
-- Could NOT find MPI_CXX (missing: MPI_CXX_LIB_NAMES MPI_CXX_WORKS) 
CMake Error at /Applications/CMake.app/Contents/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find MPI (missing: MPI_C_FOUND MPI_CXX_FOUND)
Call Stack (most recent call first):

  /Applications/CMake.app/Contents/share/cmake-3.22/Modules/FindMPI.cmake:1830 (find_package_handle_standard_args)
  CMakeLists.txt:30 (FIND_PACKAGE)

What could possibly be the workaround for this pls

It looks as if you are missing an MPI installation. You could try building without MPI as a possible workaround. It requires changing a few lines of code. Here are the instructions: https://fzenke.net/auryn/doku.php?id=manual:compileauryn&s[]=mpi#building_auryn_without_mpi I hope it helps.

Thank @fzenke I have tried following the instructions but it's leading to the below error:::

CMake Deprecation Warning at CMakeLists.txt:1 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

I have removed the AURYN_CODE_USE_MPI definition on the auryn_definitions.h but for some reason, it seems like it's still been required.

Pardon me I am new to this framework and probably that's why I am having trouble going through things.

I did my boost installation via brew.

[fzenke]

No problem, could be that something has changed or that the instructions are incomplete. Now, in the CMakeLists.txt file try replacing this part

Thanks, I have been able to install it after following the first link you shared and I mentioned earlier that I installed boost but the boost I install was just a boost but commenting out the mpi config and then installing boost-mpi works.

However, I am having issues following your tutorial from https://fzenke.net/auryn/doku.php?id=manual:compileandrunaurynsimulations

running this make sim_new Makefile:19: *** missing separator. Stop.

I keep getting the missing operator at line 19 error from the make file.

I am trying this on Mac OS is the tutorial for a different OS?

# Update the following lines to your system requirements
AURYNPATH=$(HOME)/auryn

I only tested this on Linux. The missing separator error could be due to use of space instead of tab. See for instance: https://stackoverflow.com/questions/26403917/makefile-missing-separator-in-mac-os-x

okay thank i will have a look at and see if that will fix it/
