Home › Forum › SOFA › Building SOFA › [SOLVED] Sofa (version Github) CMake V2.x backward compatibility
Tagged: 64_bits, GCC, Linux_ubuntu, SOFA_other
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.
Erik
BTW, nice to see a picture of Sofa on CMake home website!
Great job guys!
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 π
Cheers,
Guillaume.
Hi,
are you saying I’m an old dev that doesn’t use C++11 ? π
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.
Erik
