[Mesa-users] Encountering compile errors building mesa-r11554 on iMacPro

[Evan Bauer]

Hi Sam,

Awesome! That warning is an example of MESA working as intended. I see the same thing when running the default star/work directory past ZAMS.

Great question. It’s always good to start by looking in the defaults files in $MESA_DIR/star/defaults/

You can also find the defaults online at http://mesa.sourceforge.net/controls_defaults.html <http://mesa.sourceforge.net/controls_defaults.html>. In this particular case, you’ll find what you’re looking for in this entry: http://mesa.sourceforge.net/controls_defaults.html#warn_when_large_rel_run_E_err <http://mesa.sourceforge.net/controls_defaults.html#warn_when_large_rel_run_E_err>

Once you understand what’s going on, you can use the controls you find there to suppress that warning if you wish to do so.

If you want to know more about what’s going on with this warning (it’s a recent addition to MESA), I encourage you to read section 3 of the latest MESA instrument paper: https://arxiv.org/abs/1903.01426 <https://arxiv.org/abs/1903.01426>

Cheers,
Evan

In particular, it needs to come after anything anaconda might have put in there. Does that help? This might screw up anaconda, but hopefully at least MESA will install…
