Troubleshoot for Distro Maintainers
issue re2::StringPiece
$SRC_DIR/ortools/lp_data/lp_parser.cc: In function 'absl::lts_20230802::StatusOr<operations_research::glop::ParsedConstraint> operations_research::glop::ParseConstraint(absl::lts_20230802::string_view)':
$SRC_DIR/ortools/lp_data/lp_parser.cc:365:20: error: cannot convert 'absl::lts_20230802::string_view*' {aka 'std::basic_string_view<char>*'} to 'operations_research::glop::{anonymous}::StringPiece*' {aka 're2::StringPiece*'}
  365 |       ConsumeToken(&constraint, &consumed_name, &consumed_coeff);
      |                    ^~~~~~~~~~~
      |                    |
      |                    absl::lts_20230802::string_view* {aka std::basic_string_view<char>*}
answer: You need to bump re2 to at least 2023-06-01  (re2::StringPiece become an alias to absl::string_view)
issue operator<<
$PREFIX/include/absl/log/internal/log_message.h:289:17: error: no match for 'operator<<' (operand types are 'std::ostream' {aka 'std::basic_ostream<char>'} and 'const operations_research::sat::CpSolverResponse')
  289 |   view.stream() << log_internal::NullGuard<T>().Guard(v);
      |   ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
answer: You need to bump Protobuf to at least v23.3 (protobuf depends on abseil-cpp)
issue absl::int128
$SRC_DIR/ortools/sat/cuts.cc:79:36: error: no matching function for call to 'StrCat(const char [13], const absl::lts_20230802::int128&, const char [2])'
   79 |   std::string result = absl::StrCat("CutData rhs=", rhs, "\n");
      |                        ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
answer: : You need to bump abseil-cpp to at least 20230802.1 (abseil-cpp will provide a int128::toString())
