Follow-up Comment #5, bug #42176 (project octave): One wrinkle is that the ax_openmp.m4 file requires Autoconf > 2.69. I can no longer build on Ubuntu 12.04 LTS (admittedly 3 years old this April). It seems like users on really long term stable platforms like Red Hat Enterprise Linux will have the same issue. Maybe we should still enable OpenMP but continue to use our own compile test? Alternatively, there's hacking the ax_openmp.m4 file. They have an AC_PREREQ([2.69]) because they are using the _AC_LANG_PREFIX macro. Perhaps there is a way to simulate that macro through a longer sequence of commands in earlier versions. If we do just decide to go with it then we should raise the required minimum version of Autoconf in Octave's own configure.ac file and make a note that the version required for building has changed. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?42176> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
