Compilation Error on Ubuntu 22.04 (error: ‘plus’ is not a member of ‘std’) #50

Closed heuerfin closed 10 months ago

Somehow on my machine (Ubuntu 22.04 LTS) compilation fails with the following errors:

libOpenDRIVE/include/Math.hpp:47:35: error: ‘plus’ is not a member of ‘std’
libOpenDRIVE/include/Math.hpp:53:35: error: ‘minus’ is not a member of ‘std’; did you mean ‘min’?
libOpenDRIVE/include/Math.hpp:80:66: error: ‘multiplies’ is not a member of ‘std’

Even though it should be in the standard of c++14 (https://en.cppreference.com/w/cpp/utility/functional/plus) compilation fails. I've tried to update gcc and c++ from 9.4.0 to 11.3.0 but this did not resolve the issues.

After changing CMAKE_CXX_STANDARD to 17 or above, the issues are resolved (I still need to resolve https://github.com/grepthat/libOpenDRIVE/issues/46 but after that, it works).

So for anyone else with issues like that, change https://github.com/grepthat/libOpenDRIVE/blob/master/CMakeLists.txt#L8 to set(CMAKE_CXX_STANDARD 17).

From my side this issue can immediately be resolved since it isn't an issue regarding this lib. But wanted to share the issue for anyone else having trouble.
