[SOLVED] Sofa (version Github) CMake V2.x backward compatibility

[epernod]

Hi,

I just updated my version of Sofa from github and it says I need CMake V3.X :

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  CMake 3.1 or higher is required.

Can I ask why is it mandatory to have this version? Isn’t it possible to have a backward compatibility?

I’m using the default CMake from my Ubuntu which is still 2.8.12.
It is not a lot of work for me to install a CMake V3.1 in parallel but maybe it could be a bit more problematic on specific Server architecture.

Hi Erik,

Indeed, and the reason is that SOFA is now C++11 mandatory.
To do so, we had to go to CMake 3.x because using the CMAKE_CXX_STANDARD variable (only available since 3.x) was the cleanest and most easy-to-maintain solution. Check the “c++11” branch in the repo for more details.

About backward compatibility, I’m not sure this is planned. All this work was done to make SOFA move forward (C++11 is not young anymore) and open it to new developments/improvements.

Anyway, we can help you if you have any trouble staying up-to-date 😉

Cheers,
Guillaume.

Hi,

are you saying I’m an old dev that doesn’t use C++11 ? 😉

Ok I understand the need. I assume all unix servers will be C++11 compatible as well.
Thanks for the explanation. You can resolve that topic.
