Re: Package won't load after v.7 upgrade



There, you should find an Applications folder. (If not create one.)

Place your package there. I think this is the preferred place to put
packages for single users. Otherwise you might use $BaseDirectory. The old
AddOns ExtraPackages is not the right place.

With these locations packages and all your other notebooks (which might be
in folders other than Applications) will be untouched when you change
Mathematica versions.

A few days ago I was able to successfully load and use my own AddOn  
package using v.6 with Mac OSX.  My package is called "integExp.m",  
and I placed it in a folder I created called "Quantum", located at:


To load the package, I used


It loaded and ran fine. However, I upgraded to v.7 yesterday, and now  
using Needs doesn't work, and I get the following nocont and notfound  

Needs::nocont: Context Quantum`integExp` was not created when Needs  
was evaluated.

Information::notfound: Symbol integExp not found.

Did something change in v.7 regarding where to place AddOn packages?  
I've searched previous group posts and the Documentation center with  
no success.

Thanks is advance,
