You will need CMake version 3.15 as a minimum to build using the setup script. I will set the minimum version required to 3.15.

[vraj004]

Continuing on this journey, I updated cmake to cmake-3.15.1. I get the following error: CMake Error at /home/common/easybuild/software/CMake/3.15.1/share/cmake-3.15/Modules/FindPackageHandleStandardArgs.cmake:195 (message): Unknown keywords given to FIND_PACKAGE_HANDLE_STANDARD_ARGS(): "REASON_FAILURE_MESSAGE" Call Stack (most recent call first): /home/vrajagopal/opencmiss_local/opencmiss/install/share/cmake/Modules/FindPython/Support.cmake:2984 (find_package_handle_standard_args) /home/vrajagopal/opencmiss_local/opencmiss/install/share/cmake/Modules/FindPython.cmake:415 (include) CMakeLists.txt:140 (find_package)

I suspect that there might be more to this error. It seems like something has not been found, but the something is not shown in this error message. What OS is this running on? I have just tested this with CMake 3.16 on Ubuntu and things worked there.

[hsorby]

My first thought would be that numpy is not installed into the Python environment that has been detected.

[vraj004]

I have numpy installed within python3.6.4. Should that not be picked up?

[hsorby]

It should, I need a bit more context to help determine what is going wrong. From the information supplied above I cannot figure out what has happened.

[vraj004]

What additional info do you need? I'd like to document it all here so that others who search for this issue will learn from seeing the problem being worked out here.

[hsorby]

If you can configure the following in the same environment to what you are using above and post back all of the output:

cmake_minimum_required(VERSION 3.10 FATAL_ERROR)

project(TestFindPython)

set(CMAKE_MODULE_PATH "/home/vrajagopal/opencmiss_local/opencmiss/install/share/cmake/Modules")

find_package(Python COMPONENTS Interpreter Development)

[vraj004]

Hi Hugh, would you like me to make these changes in the CMakeLists.txt file in the setup folder?

[vraj004]

Also, do i need to run this still before starting? https://github.com/OpenCMISS/utilities/tree/develop/scripts

[vraj004]

I checked in FindPython3.cmake and it says it has found numpy.

[hsorby]

Sorry, I would like you to create a CMakeLists.txt file and add the above as content, save in a temporary directory somewhere and then:

mkdir build
cd build
cmake ../

I would like to see the output of that configuration.

[hsorby]

And if you were to comment out the line

# set(CMAKE_MODULE_PATH "/home/vrajagopal/opencmiss_local/opencmiss/install/share/cmake/Modules")

like so. What does that result in.

[vraj004]

[hsorby]

I cannot read properly, REASON_FAILURE_MESSAGE is only available from CMake version 3.16. That means the minimum version actually needs to be 3.16 and not 3.15. Sorry about that, I will modify the setup script and if you update it ?might? work.

[vraj004]

Thanks, Hugh. I successfully installed opencmiss-iron using cmake 3.16.4 and gcc 9.3.0.

Key issues resolved: Minimum CMake version required to compile opencmiss-iron is 3.16. Issue was not to do with oc-iron. Instead it is about cmake commands not being recognised by older versions of cmake.
