[yt-users] Installing Enzo from Yt, error!

Tue Jan 18 12:45:54 PST 2011

Hi Hector,

Not building enzo is actually a feature, not a bug.  :)  The
difference between Enzo and yt in this situation is that Enzo has
many, many moving parts -- some of which can only be determined at
build-time.  This includes things like choice of compiler, options for
how the code operates on a fundamental level, and so on.  yt has many
options as well, but it's more flexible in that (because it's written
in Python) it's more accessible to being modified at run time.

To build Enzo, I recommend you browse through the Enzo boot camp article here:

http://code.google.com/p/enzo/wiki/EnzoBootCamp

It has some links to documentation that covers the options.  Once
you've skimmed through that, if you'd like more help with building
Enzo, the enzo-users-l mailing list would be a good resource for
asking questions.

Good luck!

-Matt
