Geometry Boost List: Re: [geometry] [Boost.Geometry] Compiling errors running the official source code example "model::multi_point"

Hi,

is there a possibility how I could find out which Boost.Geometry Library
version is compatible with Compiler: gcc-c++.x86_64 version 4.8.5 since
unfortunately it is not possible for me to upgrade to a newer GCC version
but I still would like to use your library.
I ask because it was not obvious to know that Boost.Geometry Library
version 1.75 needs at least a GCC version 5 since on the official homepage
older GCC Compilers are also listed under the section "Supported
compilers":
https://www.boost.org/doc/libs/1_75_0/libs/geometry/doc/html/geometry/compilation.html

I would really appreciate your help.

Thanks a lot in advance.

Mit freundlichen Grüßen / Kind regards

"GCC 6.1 was the first release with non-experimental C++14 support,
so the API and ABI of features added in C++14 is only stable since
that release."

https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2014

https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcc/Standards.html#Standards

However, you should be fine with GCC 5 as that is the lowest
GCC version the library is CI-tested with
https://github.com/boostorg/geometry/blob/3b0898389abd8dec839f6564c6ccf748f6b38c1f/.github/workflows/minimal-gcc.yml#L23-L29

Not possible, AFAIK.
