Using -std=c++17 causes a different failure:

  /build/jeolib-jiplib-1.1.7+ds/build/src/imageclasses/VectorOgr.cc: In member function 'std::shared_ptr<VectorOgr> VectorOgr::intersect(OGRPolygon*, app::AppFactory&)':
  /build/jeolib-jiplib-1.1.7+ds/build/src/imageclasses/VectorOgr.cc:567:22: error: use of deleted function 'std::__cxx11::basic_ostringstream<_CharT, _Traits, _Alloc>::basic_ostringstream(const std::__cxx11::basic_ostringstream<_CharT, _Traits, _Alloc>&) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>]'
    567 |     throw(errorStream);
        |                      ^

The same failure occurs without -std=c++11.

I've forwarded the issue upstream.
