[Mesa-users] Installing ndiff

[Warrick Ball]

Hi Emily,

MESA's version numbers and the SDK's version numbers are different things so, though you say you say you're using SDK 7624, it's not clear what that means.  Are you using the version of the SDK from when MESA r7624 was released?  (20140715, I believe)  As far as I can tell, that SDK version includes `ndiff`, so it shouldn't be necessary to install it.

Following the advice in the MESA documentation:

     https://docs.mesastar.org/en/release-r22.05.1/installation.html#post-a-question-to-mesa-users

could you provide the outputs of

     uname -a
     gfortran -v
     echo $MESASDK_ROOT
     echo $PATH
     echo $MESA_DIR

Cheers,
Warrick
