[mesa-users] Errors showing up during installing MESA

[Matthew Clayton]

Hi Rich,

It's the MESA website. The bit I was referring to is  the "Set your environment variables" section here http://mesa.sourceforge.net/prereqs.html

Cheers,

Matthew

For example, you appear to be using bash (which is overwhelmingly likely anyway) so the command to use is 'export', but astrophysicsts like to use the C shell for reasons, in which you need to use 'setenv'. As far as I'm aware they do exactly the same thing.

Although in the website of MESA the command of setting environmental varibles for Linux and Mac are given separately I had to use both of the commands i.e. 'setenv' followed by 'export' and 'source'. Otherwise if I don't use the 'setenv' , after applying the command of 'source' it shows an error that environmental varibles are not set yet. Moreover it was showing that 'setenv' is not a valid command.I searched in web for alternative and found 'launchctl setenv' which worked fine.
