Build failed

Hello,

I ran into a problem when trying to build OSRM on Ubuntu 24.04. I followed the instructions but the build failed.

/usr/include/c++/11/bits/stl_vector.h:1204:21:   required from ‘void std::vector<_Tp, _Alloc>::push_back(std::vector<_Tp, _Alloc>::value_type&&) [with _Tp = std::variant<osrm::util::json::String, osrm::util::json::Number, osrm::util::json::Object, osrm::util::json::Array, osrm::util::json::True, osrm::util::json::False, osrm::util::json::Null>; _Alloc = std::allocator<std::variant<osrm::util::json::String, osrm::util::json::Number, osrm::util::json::Object, osrm::util::json::Array, osrm::util::json::True, osrm::util::json::False, osrm::util::json::Null> >; std::vector<_Tp, _Alloc>::value_type = std::variant<osrm::util::json::String, osrm::util::json::Number, osrm::util::json::Object, osrm::util::json::Array, osrm::util::json::True, osrm::util::json::False, osrm::util::json::Null>]’

Thank you!

What version of which compiler are you using? Are you building OSRM from master branch or from a tagged release?

[Maxim88S]

I use g++ (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 and build from master.

Looks like you're on Ubuntu 22.04 then (24.04 does not have g++-11).

g++-11 is no longer used for the OSRM CI checks, but g++-12 is and the CI builds work. You should try building using g++-12, which you can easily install on Ubuntu 22.04.
