Follow-up Comment #3, bug #68281 (group octave):

I get the following error when compiling:

../libinterp/corefcn/ls-mat5.cc: In function 'bool
save_mat5_binary_element(std::ostream&, const octave_value&, const
std::string&, bool, bool, bool, bool)':
../libinterp/corefcn/ls-mat5.cc:2626:35: error: 'std::ostringstream' {aka
'class std::__cxx11::basic_ostringstream<char>'} has no member named 'view'
 2626 |               auto buf_view = buf.view ();

It appears std::ostringstream::view() is part of C++20. Do we support that?

System Info:

gcc (Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0
libstdc++6:
  Installed: 14.2.0-4ubuntu2~24.04.1
